==Description==
These sea cucumbers reach around in length and have ten branched oral tentacles ranging in colour from orange to black.〔 This species has a football shape with a leathery skin ranging in colour from yellowish white to dark brownish-black and is covered with five rows of retractile tube feet.〔Gosner, K.L. 1978. This species of Sea Cucumber can move about two feet per day. It is able to accomplish this task by the movement of its stomach wall muscles. Peterson field guides: Atlantic seashore. Boston: Houghton Mifflin Company.〕〔Jordan, A. J. 1972. On the ecology and behaviour of ''Cucumaria frondosa'' (Echinodermata: Holothuroidea at Lamoine Beach, Maine. Ph.D. thesis, University of Maine and Orono, Orono. United States.〕 The young are about 1 mm to 6 mm long and are translucent orange and pink.〔 Three of these bands of tube feet are found on bottom whereas the top rows are often reduced. Adults of ''C. frondosa'' have a reduced numbers of spicules (skeletal structures) shaped like rounded plates with many holes.〔Levin, V. S., and Gudimova, E. N. 2000.

Bull. 13: 22-29.〕 The sexes can be identified by the conspicuous tube-shaped (female) or heart-shaped (male) gonopore located under the crown of oral tentacles.〔Hamel, J.-F. and Mercier, A. 1996a.
