Stuart Pearce Marine life under the microscope... Sepiola atlantica, the chromatophores that allow cephalopods to change colour are actually multicellular organs, not colour changing cells, which is a common misconception. They have their own muscles that can stretch the organ into a disc up too 50 times its original size. Millport Marine Biology Fieldstation, Scotland 2006.

Stuart Pearce Marine life under the microscope... Sepiola atlantica from an earlier marine biology fieldtrip, juveniles are regularly found in rockpools around UK coasts. Millport Marine Biology Fieldstation, Scotland.

Stuart Pearce Sometimes as marine biologists we are required to remove marine creatures from their natural environment when researching certain aspects of their physiology. This is always carried out under strict guidelines, and all specimens are quickly released unharmed back to where they came. My microscope shots of Sepiola atlantica were taken at Millport Marine Biology Fieldstation in Scotland, and were taken to teach students about how chromatophores allow colour change in cephalopods. Thank you to Giorgio Cavallaro Uwp, who in recent discussions said he would be happy for me to post a few of these shots on the group.

Giorgio Cavallaro Uwp Hi Stuart, thank you so much for sharing this photo, taken from your studies in marine biology, you have the shots very interesting to understand and study some marine organisms so small that you hardly get to see. Thank you for the contribution you give to science.

Stuart Pearce Thank you Giorgio :)

Annette Graves Sepiola atlantica plate....

David Campbell Working on a home page for them at http://marinebio.org/species.asp?id=1401

Annette Graves I have about 60 shots from this microscope session David, if you want to use any, no problem just let me know. :)

Annette Graves Seem to be called Bobtail Squid in most places, but here in the UK they are called Little Cuttlefish, the debate continues, thats why I have started leaving the common name off LOL :)

David Campbell Great, I'm always looking for great media for all our species home pages (cephs are especially difficult to find photos of). Feel free to email me at david@marinebio.org if you'd like to discuss it further. Common names are as variable as snow flakes it seems, I try to use the "most" common English one based on leading authorities but then again I often see common fishes with hundreds of common names in as many languages. Scientific names are much easier (until you you start looking at synonyms that is...). Keep up the great work!

Annette Graves OK, will do, got my mother in hospital for next couple of weeks, but as soon as time allows I will drop you an email, thanks :)

Stuart Pearce Marine life under the microscope... Sepiola atlantica chromatophores. The color patterns of cephalopods are largely controlled by chromatophore organs. A chromatophore organ is composed of a single chromatophore cell and numerous muscle, nerve, glial and sheath cells. Pigment granules lie within the chromatophore cell in an intracellular sac, the cytoelastic sacculus, that has elastic walls. Four to twenty four radially arranged muscle cells, with their associated nerve and glial cells, attach to the cell membrane where the latter is anchored to the cytoelastic sacculus around its equator. The contraction of the muscle cells stretches the lenticular sacculus into a thin, flat disc with serrated edges. The diameter of the sacculus expands up to about 7 times its retracted state which is equivalent to an increase in area of about 50 times. Millport Marine Biology Fieldstation, Scotland 2006.

Stuart Pearce You once asked me Ron, if I had any chromatophore shots, I kept looking, this was about the limit with the stereo microscope :)

Ron Silver Fascinating. Given enough time, I might have figured it out. My initial reaction would have been look at all of the Acoel (Waminoa sp.) flatworms.......Thanx.

Antonio Colacino A lot to learn, thanks Stuart :)

Stuart Pearce Thanks Antonio :)

Marlyse Gehrig agree with Antonio :) thx Stuard

Stuart Pearce Thanks Marlyse :)

Erling Svensen The Sepiette is a very nice fellow to meet when diving. Here from the fjords on Wednesday - night dive.

Bernard Picton Do you know which species this is Erling?

Erling Svensen Yes, I have a very good feeling for Sepiette oweniana. Too big for Sepiola atlantica, and to slim to be Rossia glaucopis, so.....

Andy Horton Identify the species ! ?

Andy Rapson I'd say one of the Sepiola family, possibly Sepiola atlantica.

Penny Martin I think it is sepiola atlantica ?? seen in Orkney this morning.

Penny Martin Or is it just a "sepia" hatchling ??? can anyone advise please?

Cynthia D. Trowbridge not a clue...we do not have cuttlefish on our coast... I do admire it though :-)

David Wilson I don't think this is a Sepia officinalis hatchling as the ones I have seen resemble miniature adults, I caught a little one like this in a shrimp net in the Salcombe estuary many years ago. At the time I thought it was Sepiola atlantica.

Andy Horton http://www.glaucus.org.uk/Sepiola.html

Andy Horton Sepietta http://www.marlin.ac.uk/speciesinformation.php?speciesID=4335

Darryl Mayer It is Sepiola atlantica aka Little Cuttlefish/Bobtail cuttlefish

Penny Martin or is it Sepietta oweniana?? How would one tell the differerence ? it definitely was showing blue bioluminescence .. see my other photos
