Diagnosis

IDENTIFICATION. Originally distinguished primarily based on the absence of phacellae, Carukia barnesi is quite distinctive in a number of features. The body is small (ca. 1 cm bell height) and quite mammillated, with an interesting reticulated pattern partitioning off each wart on the apex. The tentacles have unmistakable “handkerchief-like” or “tailed” rings, with fairly long regions of unadorned tentacle shaft in between. The rhopalial niche ostia are of the frown form, with the “rhopalial horns” very long at a strong upward angle, and the pedalial canals are simple, lacking any sort of diverticula at the bend. The velarium is quite distinctive, with 2 canals per octant, all alike in the form of simple triangles, with a single nematocyst wart on the one nearest the perradius, and the perradial lappets are present but lacking nematocyst warts. The statoliths are sub-circular in outline, without a basal concavity and lacking an apical “tooth” projection. The tentacular nematocysts are of a single type only, i.e., egg-shaped euryteles or tumiteles, 25-26 x 15-18 (Southcott, 1967).
