Husbandry

Pseudorca crassidens is a killer whale, but it is much less well known than its big cousin, the black and white orca (Orcinus orca), which is wrongly called "killer whale".
Both killer whale species belong to the dolphin family, live in social groups and are top predators at the end of the food chain.

Pseudorca crassidens is a bit smaller than the orca and, like orcas, hunts mainly in groups, although one such group also catches and eats other predators of the sea, e.g. sharks.

The dominance of the large marine hunters at the end of the food chain is countered by a growing burden of environmental toxins that are "up the food chain" and eventually reach the killer whales, such as polychlorinated biphenyls (PCBs) and mercury.
These toxins have severe health effects on the animals.
The increasing overfishing of the oceans by humans is also making it increasingly difficult for the killer whales to find sufficient food.
