(total): 27-33. Uniform light cream for the type material of West Indian Ocean species; the west Pacific form has a banded pattern (Ref. 48635).
Caught by surface dip-nets from coral rubbles and coral heads from 0 to 21.9 m. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
