Population Size(s) and Trends In the recent lUCN Cetacean Red Data Book, Klinowska (1991) noted that there is insufficient information to accurately classify the world status of this species. No information is available on popula- tion sizes or trends, nor on stock identity. In fact, very few sightings of either species of Kogia have ever been reported, and knowledge of both species comes largely from stranded animals. In some areas. Pygmy Sperm Whales are among the most frequent- ly recorded stranded species. For example, Odell (1991) noted that they are the second most frequent to strand in the southeastern United States; off the Hawaiian Islands the Pygmy Sperm Whale is the fourth most frequently stranded species (Nitta 1991). In his analysis of strandings in New Zealand, Brabyn (1991) noted that although they do not represent the largest number of individuals (as mass strandings are infrequent), Pygmy Sperm Whales are the most fre- quently recorded species. Many authors have inter- preted these frequent strandings as evidence that this species is fairly common. Recent numerous aerial sightings of Kogia (not discriminated to species) in the northern Gulf of Mexico seem to support this supposition (Jefferson et al. 1992). Only four strandings have been reported off the Canadian east coast and it appears that Pygmy Sperm Whales become more common in the south, with a greater number of records reported off the northeast coast (Early and McKenzie 1991). Habitat Pygmy Sperm Whales generally inhabit offshore waters in warm temperate and tropical areas. Brabyn (199
