Vestlet \Vest"let\, n. [Dim. of vest.] (Zo["o]l.)
Any one of several species of actinians belonging to the
genus {Cerianthus}. These animals have a long, smooth body
tapering to the base, and two separate circles of tentacles
around the mouth. They form a tough, flexible, feltlike tube
with a smooth internal lining, in which they dwell, whence
the name.
