Distribution

Distribution of Berthellina quadridens includes Mexico, Belize, Colombia, Costa Rica, Panama, Venezuela, Aruba, Curaçao, Haiti, Jamaica, Puerto Rico, Virgin Islands, Sint Maarten, St. Lucia, Guadeloupe, Martinique, Barbados, St. Vincent and the Grenadines, Grenada, Trinidad and Tobago, Brazil.[3]

The type locality is Saint Thomas, U.S. Virgin Islands.[1]

Description

Body is oval, inflated.[3] Dorsum is smooth covering the internal shell, which is located over the anterior portion of the viscera.[3] Anterior end of the body is with a large oral veil.[3] Rhinophores are rolled emerging between the veil and the dorsum.[3] Color is yellow to orange, semi-translucent.[3] It is up to 25 mm long.[3] Welch (2010) listed that the maximum recorded length is 80 mm.[4]

Ecology
Corals Orbicella faveolata are possible prey of Berthellina quadridens.[3]

Minimum recorded depth is 0 m.[4] Maximum recorded depth is 50 m.[4]

It possibly feeds on sponges and likely on the corals Orbicella faveolata and Orbicella annularis as well as on anemones.[3]

gollark: The reactor is *inside a giant energy shield*.
gollark: Don't mine the reactor. Also, you can't mine the reactor.
gollark: You probably could just wait, given the likely failure of the shield projector eventually.
gollark: I need some of that.]
gollark: I would prefer you to not nuke my plot, thanks.
