Scolanthus shrimp, a deep-water sea anemone, is known only from its type locality in Whittard Gorge about 400 km off the coast of Ireland in the Celtic Sea, North Atlantic, from 1774 meters depth.
The genera Scolanthus belongs to the subfamily Edwardsiinae, which is characterized by its nemathomata, hollow, epidermis-lined, nematocyst-dense pockets embedded in the mesoglea of the column.
The column is dark beige with eight mesenterial appendages visible when alive;
The sea anemone has sixteen small tentacles arranged in two cycles,
Tentacle length is up to 1.5 mm, they are bright orange in living specimens.
Burrowing sea anemones have a simple morphology with an elongated body and a round aboral end that anchors the animal in mud, sand, or gravel, leaving only the tentacular crown exposed.
Currently there are 14 valid species of Scolanthus distributed worldwide, but only four species have been recorded from waters deeper than 100 meters (Scolanthus ingolfi, 1,461 meters; Scolanthus nidarosiensis, 125-150 meters ; Scolanthus intermedius, 223 meters and Scolanthus triangulus, 71-271 meters).
Etymology:
The species epithet "shrimp" honors the Science Research Mentoring Program (SRMP) at AMNH and its high school students, known informally as "Srmpers."
