Although sea state has been shown to be an important predictor of sighting rates in other cetacean
habitat and trend models (Becker, 2007), the condition of the sea surface was not recorded in early CalCOFI observations and, therefore, sea state was not included in this analysis.
Such incidents are rare in the Arabian Gulf waters as such species of Cetaceans
are considered vulnerable as they find it difficult to survive in warm surface waters", the official source told Al-Ayyam.
The first, a pelagic fur seal study, during which cetacean
sightings were recorded incidentally, occurred in 1958, 1959, and 1961 (Fiscus and Niggol, 1965), which was before the first census of gray whales in central California.
Similarly, the ability to decipher an artificially derived symbolic language is a trait shared only between Cetaceans
and humans and not exhibited by other Primates.
Based on IUCN's 2008 survey of cetaceans
, both species, while still threatened, were upgraded from "Vulnerable" to "Least Concern" status on the Red List.
products qualify as "country foods" for many northern Canadian communities, and the harvest and consumption of cetacean
products has exposed northern Aboriginal peoples to health risks associated with cetacean
IN 1324, a statute was passed which gave the Crown qualified rights to cetaceans
, which include whales, dolphins and porpoises stranded on, or caught in the waters of England and Wales.
Over 16 species of cetaceans
, including whales and dolphins, are known to have appeared in Hong Kong waters, but only two of them, the Indo-Pacific humpback dolphin (or Chinese white dolphin) and the finless porpoise, live here permanently.
To respond to political stagnation and to address these problems, research and conservation organizations have recently joined forces and created a new and influential network committed to preserving marine biodiversity and reducing human impact on cetacean
The search took place almost a decade after the last exploration in 1997, which turned up only 13 of the cetaceans
phocoena increases the number of cetacean
species in the Azores region to 25 (see Farinha e Correia, 2003 for the most recent list), which corresponds to roughly 30.
The first 2 chapters cover whale biology, behavior, and some general information for each of the 14 cetacean
