Diagnosis

Deeply-folded oral disc (more pronounced with size), covered with short (average 10 mm), slightly tapering tentacles that typically all vibrate constantly. Tentacles extremely sticky in life, adhering to collector's hand, and pulling off in clumps; but do not cause stinging sensation. Typically in such shallow water that animals may be exposed at low tide. Oral disc rarely as much as 500 mm diameter, usually lies at surface of sand, often among corals; pedal disc attached to buried object. Non-adhesive verrucae on upper column blue to maroon, contrasting with yellowish, pinkish, tan, greenish-blue, or gray-green column. Basal portion of each tentacle colour of the oral disc (often tan or pink); colour of bluntly pointed distal part -- which is what is generally noted as tentacle colour -- commonly brown or greenish, rarely a striking purple or pink, deep blue, or bright green. Much of central oral disc bare, but deep oral disc folds may hide mouth.
