Description 159-165
Haloptilus specimens, collected during the International Indian Ocean Expedition, from 442 stations are examined. Of the 12 species encountered H. paralongicirrus, H. austini, H. bulliceps, H. fertilis and H. fons are new to the Indian Ocean. Most of the species are cosmopolitan in distribution, H. longicornis being the dominant species. Highest density of most of the species is noticed in the upwelling areas. H. paralongicirrus and H. oxycephalus show significant difference between day and night collections in southwest Indian Ocean during SW monsoon period. H. ornatus shows significant difference between day and night in Bay of Bengal during SW monsoon period. Comparison of number of specimens irrespective of diurnal and seasonal variations in different regions, viz. Arabian Sea, Bay of Bengal, southwest Indian Ocean and southeast Indian Ocean shows significant difference in the case of H. paralongicirrus and H. spiniceps. Arabian Sea has more number of specimens than Bay of Bengal and southwest and southeast Indian Ocean. H. ornatus shows more count in Bay of Bengal. Other species show no significant difference between regions. Comparison of 2 seasons irrespective of diurnal and regional variations shows significant difference only in the case of the dominant species H. longicornis for which NE monsoon shows more count than SW monsoon.
