Baleen whale modern mysticetes are obligate filter feeders, using their baleen to strain small prey items (including small fish, krill, copepods, and zooplankton) from seawater. Despite their carnivorous diet, a 2015 study revealed they house gut flora similar to that of terrestrial herbivores. Different kinds of prey are found in different abundances depending on location, and each type of whale is adapted to a specialized way of foraging. There are two types of feeding behaviors: skim-feeding and lunge-feeding, but some species do both depending on the type and amount of food. Lunge-feeders feed primarily on euphausiids (krill), though some smaller lunge feeders
Old Tom (killer whale) Old Tom (killer whale) Old Tom ( 1895 – 17 September 1930) was a killer whale (orca) known to whalers in the port of Eden on the southeast coast of Australia.

The whalers then allowed the killer whales to eat the tongues and lips as their share of the kill, a
