Mammals: Marine Twenty-six species of cetaceans have been recorded for the Caribbean; probably a third of these have been sighted (or are expected to occur) in Kittitian-Nevisian waters, at least during migrations (Gricks, 1994; CCA/IRF, 1991). Biodiversity Implications There is no whaling done by Kittitians or Nevisians. If whales are taken by foreign operators in national waters (and it is unlikely that any are), there are no official records. However, the country has the opportunity to protect these species through its representation on the International Whaling Commission. Many cetacean species are endangered throughout their range by hunting and/or over-fishing of their prey. An equally great threat is chemical pollution of the world's oceans. Bioaccumulation of PCBs and other toxins in the animals' fat reserves are suspected of contributing to breeding difficulties and illnesses associated with pollution-suppressed immune systems. Here we can place the various classification of marine mammals that migrate or live around Nevis with the help of marine biologists
