Abstract

I HAVE been greatly interested in Dr. C. Amirtha-lingam's communication1 about the breeding of Trochus niloticus in the Andaman Sea. My own statements on the breeding of this species in the waters of the Great Barrier Reef were based on work done by Mr. F. W. Moorhouse, at that time a member of the Great Barrier Reef Expedition and now Marine Biologist to the Government of Queensland. This work has recently been published,2 and in addition to much information about the habits and growth of this animal, Mr. Moorhouse states that it appears “to be a winter-breeder, the season extending from March to July at least, and each animal possesses a protracted spawning period”. During this period the surface temperature of the water round about Low Isles where these observations were made ranged from about a maximum of 28° C. in March to a minimum of about 20° C. in July.
