Beaded Sea Cucumber (Euapta lappa)
...a species of Synaptid sea cucumber which occurs throughout the Caribbean Sea, reaching as far south as the Lesser Antilles and Panama. A population is also known from the Canary Islands. Like other sea cucumber species E. lappa is a detritivore, using its retractable tentacles to sift through sediment, filtering out organic material for nourishment.
