ID Central

Welcome to the REEF ID Central Forum!

Anyone can browse our forums but you must be a REEF member and logged in to REEF.org to post.   You will be able to post up to 3 images for a single posting.  Our Fish and Invertebrate Identification Forum should be your first stop on the way to answering “what the heck is that critter I saw?”  Some things to consider when posting a picture to the forum are:  clarity and focus, be sure you can see the mystery critter clearly and distinguish identifying marks, full body shots are best when possible; if not clear in the picture itself, please indicate size of the fish and any behavioral notes that may help in identification; location of the sighting and other dive related information such as depth, time of year, and habitat description (check out http://www.fishbase.org for guidance on habitat use for species or a regional reference guide book). 

Please note that the geographic focus of postings to this forum should be limited to the REEF Volunteer Survey Project regions (coastal areas of North and Central America, the Caribbean, and Hawaii) and the primary taxonomic focus should be on fish and Pacific coast invertebrates.  We will not have official forum moderators.  Our cadre of experienced surveying members and other fish experts will help with identification.

Honokeana Cove Slithering Fish

Images: 
P2010183-cropped.jpg

Just as I was entering the water at Honokeana Cove to snorkel with the turtles, about a week ago, when I looked down and saw this fish.  At first I thought it was an octopus by the way it seemed to be slithering over the rocks away from where I was standing in about 3 ft. of water.  I lifted my head to tell my wife there was an octopus in the water.  When I put my head back in the water, I realized it was not an octopus but some kind of strange barbed fish.  I have checked some books on reef fish and it may be some kind of Lionfish, but I'm not really sure.  It appeared to be about 16 inches.  I am hoping someone can give me a positive ID on it.

Thanks!

Masked moray or palenose moray?

I need a positive id on this small eel.  I found lots of them on Socorro Island and Roca Partida and the boiler on San Benidicto.  Thanks

Moray identification, Socorro Islands

It's a smal eel, not like the yellow margin eels of the Cocoa Islands.  My best guess is a jeweled moray or a broadhead moray.  Any other ideas?  I found several at Roca Partida.

unfocussed fish species

Apologies for the lousey photo but that's perhaps why I'm drawing such a blank on identifying this wee beastie. I can't recall the size but surely even with the features so out of focus this looks like it has to be a pretty easy ID .... but I can find nothing in the guides or on-line. The closest I can come is a transitioning initial to terminal phase Clown Wrasse (Halichoeres maculipinna) - this was actually suggested by an acquaintance on another forum but neither of us can come up with any clinching identification.

Help would be much appreciated - I'm pretty new to this but (as a life-long birder) this new world is really very exciting! And the fact that I might (even with my all too infrequent snorkelling trips) manage to actually help with field surveys is a real bonus.

All the best,

Maui - not a sea snake

Leiuranus semicinctus - Saddled Snake Eel_0736b.JPG

I was one hour on snorkel into an herbivore survey at the Kahekili Reef, West Maui, and an unknown critter came slithering across the coral.  My camera was clipped to a utility belt and it took me a few seconds to swing it up to my face.  I've learned I may have only one chance to capture a photo, so I took a quick photo from the surface before free diving onto a fish (attached). I was only halfway down in 15 feet of sea water when the critter dove head-first into the sand and quickly disappeared.  Two photos -- from the surface, and a tail shot -- are the only evidence I have.  

My heart was pounding because it looked like a sea snake, but only the Yellow Bellied Sea Snake is rarely seen in the coastal waters of the main Hawaiian Islands.  The photos confirm it was not a sea snake, though friends who SCUBA in Palau and the Phillipines think the photo looks like a Laticauda colubrina - Yellow Lipped Sea Snake.  My tail shot confirms a pointy ending, not a paddle-like tail, so it is not a sea snake. FishBase and Keoki & Yuko Stender's Marine Life Photography websites confirm it is the Leiuranus semicinctus - Saddled Snake Eel.

Kahekili Reef is an amazing low-profile reef in front of a West Maui development that we are trying to save by letting the fish and urchins "naturally" graze down the algae, and is now a Marine Protected Area.

Blenny, goby ID

I am amazed I saw this tiny (two-inch) transparent fish.  I amazed I was able to photograph it.  I am so proud of the Photoshopping.  To me, all tiny fish are blennies or gobies.  I am guessing goby.  And, after sifting through the interactive DVD, I am guessing pallid goby.  Am I right?

January 18, 2012, Molasses Reef, Key Largo, FLorida, depth 27 feet, bottom temperature 72 degrees Fahrenheit.

Eels at night on the surface

Sorry, no photo.  When one goes shrimping in the Upper Keys on a cold wintry night, the surface is alive with eels.  They seem brownish, no pattern nor bright color.  They are usually the thickness of a pencil or a little thicker, and, if you stretched one out, I guess it would be 10 inches to two feet.  Can you tell me what kind of eels these are?

Thank You,

Marty Dick

I feel comfortable the top photo is a porgy.  Is it a saucereye porgy?  How can I tell?

The bottom photo reminds me of a harlequin bass, but it doesn't look like any in the interactive DVD.  What is it?  What are the distinguishing characteristics?

Molasses Reef, buoy M-14, December 30, 2011, depth 20 feet, bottom temperature 75 degrees Fahrenheit.  The porgy was about seven-inches long; the bottom-photo fish about half that size.

Thank You,

Marty
