ABSTRACT Fraser's dolphin (Lagenodelphis hosei) is one of the least studied dolphin species due to its tropical, offshore distribution and low density. However, it is frequently observed in the Lesser Antilles, where we characterized its distribution and ecology using 4 years of data collected from Grenada to Anguilla.

KILLER WHALE PREDATION ON SPERM WHALES: OBSERVATIONS AND IMPLICATIONS
AbstractIn October 1997 we observed a herd of approximately 35 killer whales (Orcinus orca) attack a pod of nine sperm whales (Physeter macrocephalus) 130 km off the coast of central California. During the four hours we watched, adult female killer whales, including some with calves, attacked in waves of four to five animals in what was apparently a ...

Seasonal Abundance and Distribution of Cetaceans in a High Traffic Shipping Corridor
ABSTRACT The recovery of many cetacean species coincides spatially and temporally with intensifying anthropogenic threats. We undertook multi‐year systematic surveys to quantify seasonal abundance and document the distribution of at‐risk cetaceans, which is needed to assess the impacts of increasing human activities in the Canadian portions of the ...
