Odobenidae (Walruses) is a family of mammals. Reproduction is viviparous. They rely on lift powered swimming to move around.

  • URI: https://eol.org/schema/terms/lift_based_swimming
  • Definition: Hydrofoils, or fins, are used to push against the water to create a normal force to provide thrust, propelling the animal through water. The reduction of fin cross-sectional area helps to minimize drag, and therefore increase efficiency. Regardless of size of the animal, at any particular speed, maximum possible lift is proportional to (wing area) x (speed)<sup>2</sup>. Dolphins and whales have large, horizontal caudal hydrofoils, while many fish and sharks have vertical caudal hydrofoils.
