 RIGHT WHALE
Right whales were named by whalers who considered them the "right" whales to hunt, since they were rich in blubber, they were easy to catch (they are relatively slow swimmers) and they floated after being killed.
Right whales (like all baleen whales) are seasonal feeders and carnivores that filter feed plankton and tiny crustaceans like copepods, krill, pteropods, etc., from the water.
The right whale gestation period is about 12 months and the calf is born tail first (this is normal for cetaceans) and near the surface.
