Sea Cucumbers in Key Largo

[DamselDoc]

I have 2 sea cucumbers that I need some help identifying. I think the first is the 5 tooth sea cucumber. The second may be a donkey dung sea cucumber (although "the book" says these are not found in the Keys). These guesses are based on Paul Humann's Reef Creature, but there are not a lot of varieties shown. Both were photographed on the Spiegel Grove in about 80'.

Thank you if you can lend help...

Looks like a 3-rowed sea cucumber.

All the donkey dung's I've seen are dark in colour. And less pebbly.
