Cetacean sightings, mixed-species assemblages and the easternmost record of Indopacetus pacificus from the northern Indian ocean

چکیده
A visual survey of cetaceans was carried out during a voyage from Singapore to Sri Lanka, through the Straits of Malacca, Andaman Sea and across the Bay of Bengal in the northern Indian Ocean in November/December 2012. Forty sightings of 11 cetacean species were recorded in 19 days of observation. Two mixed-species associations of interest were recorded. One of these contained four species of odontocetes in association with each other. The second group was of Indopacetus pacificus in association with Globicephala macrorhynchus and this while being the easternmost live sighting of I. pacificus in the northern Indian Ocean is also the first such mixed group in the Bay of Bengal.

Cetacean sightings and acoustic detections in the offshore waters
The Indian Ocean Sanctuary was established in 1979 in an effort to allow exploited stocks of whales to recover from whaling and to facilitate benign research. Further information is required to establish comprehensive management and conservation measures for species within these waters. The current study took place in the offshore waters of Sri Lanka in early 2003. During three research cruises...

—To understand how well fossil assemblages represent original communities, paleoecologists seek comparisons between death assemblages and their source communities. These comparisons have traditionally used nearshore, marine invertebrate assemblages for their logistical ease, high abundance, and comparable census data from living communities. For large marine vertebrates, like cetaceans, measuri...
