Melanella sp. 7, if these are all correctly identified, have been found a number of sea cucumber species, including Thelenota anax, Stichopus chloronotus and a couple of species of Bohadschia, B. argus and B. ocellata. These are quite similar to Melanella sp. 2 and may be variations of that species. The first photos are of a specimen from T. anax.
The next few are from Bohadschia argus and B. ocellata.
The one appears to have its feeding proboscis embedded in the sea cucumber.
Animal retracted into the shell.
The next few were on Bohadschia cf vitiensis.
