Figure 1B

#0150, one; #1191B, thorax only; #1226; #3786, three; #4617, one, 5.3 cm in length.

This species is always solitary, the thorax yellow, with the abdomen embedded in crevices or coral rubble and with only the thorax protruding in its thick opaque bright yellow tunic. Thus collected specimens are often broken off at the narrow neck between thorax and abdomen and only the thorax is collected.

Widely distributed in the tropical west Pacific including Indonesia, Hong Kong, Philippines, Singapore, Sri Lanka, Japan, Mozambique, Papua New Guinea, Guam.
