Blenny Auction Result

Malacoctenus carrowi Peter Wirtz

Malacoctenus carrowi by Dr. Peter Wirtz

Meet Malacoctenus carrowi, a newly described blenny known from the Cape Verde Islands in the eastern Atlantic. A year ago, we announced a Blenny Auction to raise funding to enable Dr. Peter Wirtz to collect another specimen and complete the research to formalize the description of the fish, only the second species of the genus Malacoctenus to be known from the eastern Atlantic. As a result, the species has been named to honor Mr. Frank Carrow, whose interest in marine conservation led to his creation and funding of a foundation that supports a broad range of marine conservation activities. The paper, A new species of Malacoctenus from the Cape Verde islands, eastern Atlantic (Pisces Teleostei Labrisomidae) is available online.  For more information about the books, publications and images of Dr. Wirtz, visit his web page at

Happy Friday everyone!

The Real Secretary Blenny

Secretary Blenny Acanthemblemaria maria

The real Secretary Blenny, Acanthemblemaria maria

November, 2014 ~ If you have a photo of a blenny labeled Secretary Blenny, Acanthemblemaria maria, it is likely that you actually have a photo of a Spinyhead Blenny, Acanthemblemaria spinosa. A Google image search for “secretary blenny” produces pages and pages of images that are actually, with an occasional exception, Spinyhead Blennies. I have intimate knowledge of this problem — it has been wrong in Reef Fish Identification – Florida Caribbean Bahamas since the second edition (1994) and just sorted out in the recently published fourth edition of the book. Our field guides are written to help divers visually identify fishes in their natural habitat and even after 25 years, Ned and Paul still consider them to be works in progress, adding additional species and corrections, whenever practical, to new printings and editions. The Spinyhead Blenny – Punk/Christmas Tree Blenny – Secretary Blenny correction has been a long time in coming but with the help of Dr. Ben Victor the confusion has finally been cleared up.

November 2014: A Google image search for "secretary blenny" yields mostly misidentified fish.

A Google image search for “secretary blenny” yields mostly misidentified fish.

Figuring out how to visually tell the fishes of the genus Acanthemblemaria apart has long been an obsession of mine;  I read scientific descriptions, examined Ned’s photos (first slides, then enlarged digital images) and experimented with various macro options on my video camera. Everything seems obvious on paper or the computer screen but underwater, in a surge, identifying a tiny, moving fish presents many difficulties. Along the way, I’ve learned some interesting things, including how the Secretary Blenny got its name. If you are only interested in the details of how to tell the two species apart, then skip down to the end of this post where there is also a link to a short video.

Spinyhead Blenny by Ned DeLoach

Spinyhead Blenny, Acanthemblemaria spinosa

Fishes in the genus Acanthemblemaria are small, tube-dwelling blennies, distinguished from other blennies in the family Chaenopsidae by the presence of spines on their heads and around their eyes. The spines are not to be confused with cirri – the fleshy stalks over the eyes and snout – or the papillae, soft protuberances, which are present on the heads of some of the acanthemblemariids (A. medusa and A. chaplini). The number, size and shapes of these spines, cirri and papillae are features that distinguish one species of the genus from another, but these features are usually so small that it is difficult to discern the differences without the aid of magnification and a very still fish. One of my all time favorite publications about blennies is Atlantic Fishes of the Genus Acanthemblemaria, with Description of Three New Species and Comments on Pacific Species (Clinidae: Chaenopsinae) by William F. Smith-Vaniz and Francisco J. Palacio. For years, I pored over the descriptions in this paper and obsessed over the illustrations of the cranial spines and cirri, but just could not match them with what we were seeing underwater on live fish.

About nine years ago, in an effort to establish a visual identification key for divers, we consulted Dr. Bill Smith-Vaniz. Under his direction, we obtained a collecting permit in Bonaire and collected a number of specimens of what we thought were Secretary, Spinyhead and Medusa blennies. Our friend Claire Davies helped us locate, photograph and collect the fishes. Our goal was to work out a key for fishwatchers, using Ned’s photos, matched to the positive identifications obtained from Bill’s examination of the collected fishes.  But the results came back from Bill’s lab revealing that our collected fish were all Spinyheads and Medusas – not a Secretary in the bunch, even though we were certain we had collected some! That was important reinforcement that something was amiss in the visual identification of these fishes, but other projects took precedence and we set the question aside.

Secretary Blenny from St Vincent by Ned DeLoach

What people were calling the Punk is actually the Secretary Blenny

The next year, we visited St. Vincent, where we were shown the Punk Blenny, a reportedly undescribed Acanthemblemaria species that received its common name from the red flattop of spines on its head. In other areas, there were reports of a blenny that fishwatchers were calling the Christmas Tree Blenny, for its distinctive cirri. Around the same time, I saw a post in an online forum requesting help in determining whether a fish was a Spinyhead or Secretary Blenny and Ben Victor’s response, that the “CDs and books are wrong” and the Punk Blenny is the real Secretary Blenny. Ned and I finally had the opportunity to talk to Ben at length about the Secretary/Spinyhead confusion when he joined the ReefNet team and us for a two-week dive trip to Dominica in 2010 and we enlisted him to help set the record straight. Ben is both an ichthyologist and medical doctor who has conducted extensive research on larval fishes of the Caribbean (his site: ) and is familiar with the distribution of fishes based on collection records throughout the tropical western Atlantic. Ben confirmed that there is no such thing as a Punk or Christmas Tree Blenny. After asking around, I am pretty sure the Christmas Tree and Punk blennies were references to the same fish although it is possible that what people were calling Christmas Tree Blennies were actually Medusa Blennies (A. medusa).

Secretary Blenny out of hole by Ned DeLoach

Secretary Blenny (A. maria) stretches out of its hole.

While waiting for the publication of the fourth edition of Reef Fish Identification with its additional photos and corrected identifications, I decided to dig into the scientific literature about Secretary and Spinyhead blennies. The Spinyhead, Acanthemblemaria spinosa, was originally described in 1917 from specimens taken in Curacao. In 1928, William Beebe and John Tee-Van described Acanthemblemaria variegata. In 1941, this was temporarily made a synonym of, i.e., considered the same species as, the Spinyhead (A. spinosa) by Longley and Hildebrand. In 1957, James Böhlke published The Bahaman Species of Emblemariid Blennies, in which he summarized the Acanthemblemariids known to date in the Bahamas. In discussing the Spinyhead, he includes the work of both Beebe and Tee-Van (A. variegata) and Longley and Hildebrand and noted some differences in spine counts between his specimens and those described by Longley and Hildebrand indicating that, “It is possible that A. variegata is the true spinosa and the above specimens represent an undescribed species;”

Sure enough, in 1961, he published, The Atlantic species of the clinid fish genus Acanthemblemaria, in which he sets the record straight, that A.variegata Beebe and Tee-Van is actually A. spinosa - the Spinyhead originally described in 1919 – and the blenny that was troubling him in his 1957 paper was in fact a new species, Acanthemblemaria maria, which he “Named for Mrs. Mary George, my secretary for the past five years and now parent and housewife, in appreciation of her assistance in all the activities of the department during that period.” So the new blenny was named to honor to Dr. Böhlke’s secretary, Mary George, hence the common name, Secretary Blenny (I love little tidbits about how fishes are named – see my Arrow Blenny post). I’ve heard suggestions that the common name should just be changed to Punk Blenny, but in deference to Dr. Böhlke and Mary George, I truly hope that never happens. The name “punk blenny” just adds to the confusion and should be dropped completely.

Spinyhead (Acanthemblemaria spinosa) vs. Secretary Blenny (Acanthemblemaria maria)

So to summarize: If you have a picture of a Punk or Christmas Tree Blenny, it is most likely a true Secretary Blenny. If you have a blenny photo labeled Secretary Blenny, check it again to make sure it isn’t really a Spinyhead Blenny. Both species have similar markings, including spots on their lips (except the Bahamas, where Secretaries’ lips have lines – note from Ben Victor). Spinyheads tend to have many uniform, short head spines, while Secretaries have fewer that are larger. The differences in their cirri are very difficult to see with the naked eye. The Secretary Blenny has a very distinctive orange patch over the back of the head, tends to be larger than Spinyheads and we have always found them in areas of high-energy or surgy water and rarely below 25 feet. Ben also notes, “There are no records of Secretary blennies in Florida or Bonaire. There are no records of Spinyheads in Florida or Panama.”

Unsure of your blenny? Here is a short video of the two (click on the video or this link: ) and be sure to like our FaceBook Blennywatcher page for more updates.

Banda Sea Images

Decorator crab off Pantar, Indonesia by Ned DeLoachBanda Sea, April 2014 ~ This algae covered decorator crab, found by Ned on a night dive off Pantar, Indonesia, is one of my favorite images from our April trip around the Banda Sea. We boarded the Dewi Nusantara in Ambon and dived our way down through and around the southern perimeter of the Banda Sea and across through the Alor region, ending in Flores. And oh, what a trip!

Last year, I posted about the little bryozoan goby that Graham Abbott found in Ambon. We looked for it all the way down from Halmahera to Ambon, but only found it in Ambon at the end of our cruise. This year, our trip started in Ambon, so we searched for it as we traveled south but didn’t find it until we reached Alor. After we blogged about it last year, the fish became quite an attraction with the dive operators in Ambon and I shared information about how to find these tiny, cryptic fish with others. I am pleased to say that one of them found the goby in Lembeh a few months ago, so it is now known from Ambon, Alor and Lembeh. I can understand Ambon and Alor, but I find it interesting this fish wasn’t seen earlier in Lembeh, a muck diving mecca visited by thousands of divers. Just shows how knowing something exists can often be the key to more sightings.

Another fish that we have been searching for is Cirrhilabrus humanni, a fairy wrasse I discovered in 2010 off Pura Island and formally described by Dr. Gerry Allen in 2012. During our 2010 trip, I only saw the one male with a harem of many females so we were keen to know more about its range. This time our friend, Dr. Richard Smith, was the first to find one. Alerted to its presence by Richard, we found a couple more on the dive site off Alor. Richard’s wonderful shot is posted on his site,

I have seen many Midas Blennies, but never one in its courting colors. The banded pattern caught my attention but it took a while to realize which blenny it was because it was so large. I pestered Ned until he went back with me to take photos. One shallow outcropping sported a highly motivated population of at least eight males. Midas Blenny Ned DeLoach

On an early morning dive, our guide Yann pointed out Red-margined Wrasse, also flashing bright courting colors.Red-margined Wrasse by Ned DeLoach

I found this stunner, a flasher wrasse (possibly undescribed), on a late afternoon dive and finally got the attention of Ned, our guide Yann and our friend Dave Dempsey, who were equally impressed! We were able to return the next day so everyone else could see these beauties.Wrasse in Alor region Ned Deloach

Night dives almost always yield fabulous creatures like this bumblebee shrimp perched on a brightly colored sea apple. Bumblebee shrimp feed on the tube feet of echinoderms, which is why we often find them on sea cucumbers and urchins.Bumblebee shrimp in sea apple by Ned DeLoach

You can get an idea of how small this Bobtail squid is by comparing it to the shrimp it is holding. Ned shot this photo as the squid was capturing its dinner.Bobtail squid eating a shrimp Ned DeLoach

Who can resist a teddy bear? During a mucky night dive, Ned found this Teddy Bear Crab out bimbling around. I touched it – couldn’t resist – it was so soft.Teddy Bear Crab off Alor Indonesia by Ned DeLoach

It is hard to believe that this tiny Pinnate Batfish grows up to be a large, rather nondescript silver-gray fish.Pinnate Batfish Alor Indonesia by Ned DeLoach

This cuttlefish was not impressed with Ned and his camera. Here, it exhibits what I think is a threat display.Cuttlefish off Pantar by Ned DeLoach

It isn’t uncommon to see Fire Dartfish singly or in pairs, but just outside of Banda, I found a group of almost 20! True to their name, they darted into their holes when we approached but Ned caught a respectable number in his shot.Dartfish Banda Sea Ned DeLoach

We close with happy bees of Banda – we had a lovely morning walking tour of a nutmeg plantation and fort on Banda Neira. Happy Bees, Banda Neira, Indonesia

The Most Photographed Tessellated Blenny in the World

Tessellated Blenny's colorful neck by Ned DeLoachThis is the most photographed Tessellated Blenny in the world and likely the most observed. I am certain of this. I spent hours with this fish and its reefmates –  I think I might have been obsessed. A few days after we arrived on Bonaire for our annual 5-week stay, our friends Allison and Carlos Estape (fellow fish surveyors) stopped by and told us about a site that had Tessellated Blennies (Hypsoblennius invemar) living in the barnacle shells. An abandoned, submerged mooring covered with a complex growth of sponges, barnacles and other invertebrates, this was perfect habitat for Tessellated Blennies. Enchanted by these colorful fish, we visited the site, dubbed the “blenny condo,” again and again regularly finding from 12 to 15 individuals, including one only a half-inch long.

The Tessellated Blenny that started it all Ned DeLoachAbove: another view of the same blenny. Of all the blennies at the condo, this individual had the most developed cirri. It was also the most photogenic, sitting in a barnacle shell that was free of surrounding growth. Over five weeks, Ned and I showed it and the others in the colony to many fishwatchers and photographers – anyone who was willing to spend an hour at eight feet to look at a tiny, 2-inch fish. Although the mooring was attached to the bottom, at a depth of 26 feet, all the blennies I counted were in the top ten feet of water. Looking up, you can see how close the top of the mooring is to the surface:The Bonaire Blenny condo by Ned DeLoach

Hanging out at ten feet could be tough when it was surgy, but we made a number of dawn dives, when the water was calmer and the blennies were particularly active. I was able to distinguish some of the females from the males by their behavior. In many blennies, the nuptial males are colored differently from the females and young, non-breeding males. They are usually site attached, rarely leaving their holes – I think this is because they are either guarding eggs or trying to attract females to lay eggs there. The Tessellated Blennies that never left their holes were the most vibrantly colored and strongly patterned, which led me to believe they were the males. When what I thought was a female approached, the males exhibited a very distinctive head-bobbing behavior, often leaning way out of the hole, like this one:Tessellated Blenny trying to attract a female by Ned DeLoach

I could not tell the difference between the females and young males, but many were running around and getting into frequent fights with each other. When I saw a male going crazy, bobbing up and down like a mini-piston, I was certain the target of his showboating was a female, like this one that tucked itself into a shell after running around the male several times:Tessellated Blenny Female by Ned DeLoach

Ned shot dozens of photos of the Tessellated Blennies on the blenny condo but this is my favorite. I wuv de widdle toofees: The Laughing Blenny by Ned DeLoach
