Holothuria moebii Ludwig is a species of sea cucumbers in the Holothuriidae
They are abundant in the body wall and are also particularly concentrated in the Cuvierian tubules, a specialized defense system developed by some sea cucumber species of the family Holothuriidae
(Matsuno and Iba, 1966; Elyakov et al, 1973).

However, most species in the holothurian families Holothuriidae
and Stichopodidae (order Aspidochirota) and Synaptidae (order Apoda) develop through the characteristic planktotrophic auricularia larvae (Sewell and McEuen, 2002).

The largest solid organ next to the body wall in the species in Holothuriidae
was the circular and longitudinal body-wall muscle, occupying about 5%; in S.

Almost 50% of the aspidochirote holothurians are within the Family Holothuriidae (Smiley, 1994).
We conclude that the tubule recruitment model may be appropriate for a number of species in the aspidochirote families Stichopodidae and Holothuriidae.
