Posted by Jim on August 25, 2014 at 13:47:54: Cozumel, August 2014 - Year of the Pipehorse
Amphelikturus dendriticus, also known as Acentronura dendritica, is a species of pygmy pipehorse native to the western Atlantic Ocean. Similar to pipefish and seahorses, there is scientific debate about how pipehorses are related. Currently, the pipehorse is the only known member of its genus. Due to its small size (about one-inch), coloration, and habitat, this highly camouflaged creature is rarely seen. While we have found a few individuals in Cozumel before, thanks to the keen eyes of our dive master, we were fortunate to encounter many specimens on this trip – very, very exciting for even this experienced Cozumel diver. Pipehorse (Amphelikturus dentriticus) Pipehorses differ from seahorses in many ways: the pipehorse has a single gill opening on the back of the head while seahorses have two on the sides, the male pipehorse broods the young inside their trunk while seahorses brood them in a pouch on the tail, and the pipehorse's head is an extension of the trunk while seahorse heads are angled downward. Longsnout seahorse (Hippocampus reidi) The pipehorse should also not be confused with the pipefish, which does not have a prehensile tail among other physiological differences. Diamond pipefish (unidentified) “Welcome home!”
Day 1 Shore dive. After arriving at SCC, checking in, having lunch, and unpacking, we grabbed a couple of tanks and went for a shore dive in front of the hotel. Entry is easy, down metal steps into a well that leads to the open water. There is a lot to see and photograph if you move slowly and look for little stuff. Robin Tackett has posted a great U-Tube video highlighting the artificial reefs and critters directly offshore. Check it out: Shore Diving at Scuba Club Cozumel Yellowline arrow crab (Stenorhynchus seticornis) Banded coral shrimp (Stenopus hispidus) Scrawled cowfish (Acanthostracion quadricornis) Goldentail moray (Gymnothorax miliaris) Sand diver (Synodus intermedius) True tulip (Fasciolaria tulipa) laying eggs. I went back a couple of days later to take a better picture of the egg cases; they look like little flowers.
Day 2 Coral Diver with Jesús, Wayne & Jayson (Montreal), Tim & Julie (Oklahoma), Deborah and me.
San Francisco Deborah found the first pipehorse!!!!! (Amphelikturus dendriticus) Spotted scorpionfish (Scorpaena plumieri)

Shopping trip to Mega and Chedraui for coffee cups and a rinse bucket for the cameras.

The sphinx. Spotted scorpionfish (Scorpaena plumieri) Spotted cleaner shrimp (Pericimenes yucantanicus)
Day 4 Coral Diver with Jesús, et al.
Palancar Gardens
Dolphins! This is a lousy picture - as the dolphins swam by, I just pointed the camera and pushed the shutter. In many, many years of diving, I've only seen dolphins underwater a handful of times. Grouper (Mycteroperca sp) Hawksbill turtle (Eretmochelys imbriocota)
Chankanaab reef Flock of blue tangs (Acanthurus coeruleus) Milk conch (Strombus costatus) Coney (Cephalopholis fulvus) – golden juvenile. Moving onto the sand, inshore from the reef, Jesús found a couple of large seahorses hiding in plain sight.
Day 5 Coral Dive with Jesús, the group plus George. Today is Jason’s fifteenth birthday! Colombia Reef
Hawksbill turtle
Fringe-back nudibranch (Dondice occidentalis) is a new find for us. Despite many, many years of diving in Cozumel’s waters, it seems we always find something new. This seaslug is very, very small as shown by my fingernail. Little red nudi (Gastropteron chacmol). Yocab reef Scrawled filefish (Aluterus scriptus) Great barracuda (Sphyraena barracuda) at a cleaning station.
Fiesta!
Day 6 Coral Diver with Jesús, Mike, George, Deborah and me. Only four divers with our own dive guide – sweet! El Paso del Cedral, the wall and the reef. Contrary to popular belief, this isn’t Cedar Reef, but is named for its location near the road into the town of Cedral in the middle of the island. Blowing current on the wall so, at the end of the reef, we swam over to the inshore reef and did two dives for the price of one. Black gGrouper (Mycteroperca bonaci)
Green moray (Gymnothorax funebris) Grouper (Mycteroperca sp) A signature picture from el Paso del Cedral Guess what! More pipehorses…three on one dive!
Paradise reef. We started at the beginning of the coral formation before moving off into the shallows to look for little stuff. The current switched directions and we drifted back to the beginning of the dive site. Fringed filefish (Monacanthus ciliatus) playing hide-and-go-seek in a gorgonium. Flamingo tongues (Cyphoma gibbosum) are normally pretty dormant, but this one was actively crawling around. Can you see the “eye” spot at the base of the antenna? Cottonwick (Haemulon melanurum) The bubbles are flamingo tongue egg cases. Shore dive Fish eggs Blue tang (Acanthurus coeruleus) being cleaned by a juvenile angelfish Juvenile scorpionfish (Scorpaenodes sp) Spotted cleaner shrimp (Pericimenes yucantanicus)

Day 8 Coral Diver with Jesús, Mike, George, Jim & Jan, and us.
La Francesa Tunnels! Parallel to the edge of the reef is a tunnel system that runs much of the length of the coral formation. This is a great place to look for large lobsters, crab, and green morays, or just enjoy the windows and shafts of sunlight filtering down through cracks in the rock. Unfortunately the green moray that we found was hidden, with only a tail showing.
Spotted drum (Equetus punctatus) intermediate stage Punta Tunich Midnight parrotfish (Scarus coelestinus) "Coming through! Make way!" Black grouper (Mycteroperca bonaci) Porkfish and grunts Spotted drum Gray angelfish (Pomacanthus arcuatus)
