038C8C19FFD5FF847CB5FDB7FE73FAF5.taxon	distribution	Distribution. The five specimens were collected in sandy muds bottom (<10 meters), in only one sample in the area, and in these conditions, it was difficult to give some valuable data on the biology, ecology, ethology, distribution, of the species. The mouthpart of Haploops antennata is characteristic of the genus Haploops which are essentially filter feeders.	en	Kaim-Malka, R. A.
