ID help please

Can someone help with an ID for any of these critters? These were photographed in Florida and the Bahamas.

Thanks!

I suspect that the second shot is a juvenile trunkfish (Lactophrys trigonus). Juveniles of this species are supposed to show a pattern of white spots, and have a mid-dorsal ridge... both of which one could argue are present in this photo (btw - great shot!).

Cephalopods aren't my thing though, so I'll leave them for someone else to tackle... awesome shots though!! Well placed DOF in the first one, and love the colours/reflections in the third.

I reckon the other two are Caribbean reef squid, Sepioteuthis sepioidea.

Thanks, Keri. I had a feeling it was one of the juvenile trunks but the green rings (instead of the white/yellow spots I normally see) threw me off. Thanks for the nice compliments on the photos.

Nick, the chromatophores on squids are what always confuse the heck out of me. Supposedly that is one way to tell them apart. I know that the Lolliguncula sp. has no red chromatophores... only yellow and brown plus they are short and stubby. That leads me to believe the last image is Lolliguncula, but I'm not certain. It was photographed while snorkeling in 1400 ft. in the Bahamas. There was a huge school of them and they were a maximum size of 3 inches.

The one in the first photo I'm almost certain the genus is Loligo but I don't know the species. That one was photographed at Phil Foster park (Blue Heron bridge) in 10 ft. of water.

Can anyone recommend a good cephalopod identification book that covers Florida and Bahamas?

the first squid actually looks like an arrow squid. which is a much rarer find

its narrower with bigger fins in proportion to its body

than the reef squid. and if you look closely, the reef squid fins start much closer

to the head than the other squid. nice shots by the way
