I'm wondering if someone can identify this shell from 69 feet on the reef wall outside the boat channel of Majuro in the Marshall Islands.
It's 3.5 mm in length.

The shell in sea hares [see Fact Sheet] is in the process of disappearing and so has becaome a fairly featureless structure. In the genus Aplysia, with few exceptions, it is very difficult to identify shells to the species level. At 3.5 mm in length I suspect your shell is from a juvenile, but to cpmpound thhe problem, juvenile shells are amost impossible to identify to species. The most likely small species your would find is Aplysia parvula and its shell is more elongate in shape and usually quite brown.
