Title Distribution, ecology and polymorphic behaviour of the genus Oxycephalus (Hyperiidea, Oxycephalidae) in the Indian Ocean
 
Creator Nair, K.K.C.
 
Description There have been many controversies on the number of valid, species under Oxycephalus including the studies made from Indian waters. This is the first comprehensive account on the distribution of this genus covering the entire Indian Ocean through seasons. There exist only three valid species under Oxycephalus, O. clausi, O. piscator and O. latirostris, which are mostly circumtropical, in my contention. Hitherto it was believed that females of O. latirostris do not show dimorphism, unlike the other two species. Females of O. latirostris collected from the Bay of Bengal and south-central Indian Ocean show pronounced dimorphic characters. Polymorphic behaviour is mostly restricted to O. piscator, mainly due to post-maturity growth. The geographic variations in length are discussed in detail for the first time
