Whales are sea mammals. Some varieties of these seagoing mammals are among the largest animals known. Relatively small whales (such as the orca) can be vicious predators, attacking virtually anything they detect. The tuskarr can point out every kind of whale imaginable and a few that may not be real, and they hunt all of them. Whales can “see” by emitting high-frequency sounds, inaudible to most other creatures, that allow them to locate objects and creatures within 120 feet. A silence spell negates this and forces the whale to rely on its vision, which is approximately as good as a human’s. A whale can hold its breath for a long time before it risks drowning.
Orca whales (aka orcas or killer whales) are ferocious creatures. They are relatively small whales.
Baleen whales are a large type of whale. They are plankton-feeding whales between 30-60 feet long. Species include gray, humpback, and right whales.

Yet even their enemies marvel at the tuskarr's prowess and fearlessness in catching some of the most dangerous creatures in Northrend's frigid waters, including whales and giant squid. Not even the unnamed leviathans that lurk in the ocean's depths are beyond the tuskarr's reach.
