what class of vertebrates do seals belong to
Pinniped Pinnipeds,[a] commonly known as seals,[b] are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic marine mammals. They comprise the extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals). There are 33 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular evidence supports them as a monophyletic lineage (descended from one ancestral line). Pinnipeds belong to the order Carnivora and their closest living relatives are bears and musteloids (weasels, raccoons, skunks, and red pandas), having diverged about 50 million years ago.
United States Navy SEALs The first two teams were formed in January 1962[30] and stationed on both US coasts: Team ONE at Naval Amphibious Base Coronado, in San Diego, California and Team TWO at Naval Amphibious Base Little Creek, in Virginia Beach, Virginia. Formed entirely with personnel from UDTs, the SEALs mission was to conduct counter guerilla warfare and clandestine operations in maritime and riverine environments.[8] Men of the newly formed SEAL Teams were trained in such unconventional areas as hand-to-hand combat, high-altitude parachuting, demolitions, and foreign languages. The SEALs attended Underwater Demolition Team replacement training and they spent some time training in UDTs. Upon making it to a SEAL team, they would undergo a SEAL Basic Indoctrination (SBI) training class at Camp Kerry in the Cuyamaca Mountains. After SBI training class, they would enter a platoon and conduct platoon training.
