Pacific
White-sided Dolphin
Lagenorhynchus obliquidens
Description
- A dark grey or black back broken by white or light
grey stripe along the flank characterizes the colouring
of the Pacific White-sided Dolphin. The beak, front
edge of dorsal fin, flippers and flukes are dark; the
belly white.
Distribution - The Pacific White-sided Dolphin inhabits
coastal British Coluimbia and the entire Pacific range.
It is considered a deepwater species but in recent years
these dolphins have been seen closer to shore and in
inland waters.
Biology - This fast, powerful swimmer loves to bow
ride and surf; they often leap and somersault. They
are nearly always found in groups of less than 50 animals.
Primary foodstuff is squid and small fish. This dolphin
is considered common and not endangered; some are harvested
for food by the Japanese and several thousand are caught
in drift nets and the tuna fishery each year.
