Berardius

Berardius

 

a genus of whales of the family Ziphiidae. Two pairs of flattened teeth are present in the lower jaw. The whales live in schools and feed on cephalopod mollusks. Feeding involves deep and prolonged dives. There are two species: Baird’s whale (B. bairdi) and B. arnouxi. Female Baird’s whales reach a length of 12.5 m, and males 11 m. Baird’s whales live in the North Pacific, including the Sea of Japan, the Sea of Okhotsk, and the Bering Sea. B. arnouxi, which measures up to 11 m long, is found in the southern hemisphere to the antarctic. Japan is the only country that hunts the two species commercially.

The absence of California sightings for two beaked whale genera (Mesoplodon and Berardius, Table 7) since 1996 is disconcerting, especially in light of recent discoveries about the susceptibility of this group to loud anthropogenic sounds (Simmonds and Lopez-Jurado, 1991; Cox et al.

In odontocete males, these characteristics are present in the form of "weapons," such as the tusk of the narwhal (Monodon monoceros) and the teeth in species of the genus Grampus, Physeter, Berardius, Hyperoodon, and Mesoplodon used in male-male combats (MacLeod, 1998).
