2018 California Academy of Sciences cc-by-nc-sa-3.0

Phocoenoides dalli (Dall Porpoise) is a species of mammals in the family porpoises. They are listed in cites appendix ii. They are native to Pacific Ocean. They are carnivores. Individuals are known to live for 264 months and can grow to 239 cm. They have parental care (female provides care). They rely on swimming and lift powered swimming to move around.

URI: http://eol.org/schema/terms/CITES_II
Definition: Appendix II lists species that are not necessarily now threatened with extinction but that may become so unless trade is closely controlled. It also includes so-called "look-alike species", i.e. species whose specimens in trade look like those of species listed for conservation reasons. International trade in specimens of Appendix-II species may be authorized by the granting of an export permit or re-export certificate. No import permit is necessary for these species under CITES (although a permit is needed in some countries that have taken stricter measures than CITES requires). Permits or certificates should only be granted if the relevant authorities are satisfied that certain conditions are met, above all that trade will not be detrimental to the survival of the species in the wild. (See Article IV of the Convention)

Definition: Self-propelled movement of an organism from one location to another through water, often by means of active fin movement.

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.
