In quantum mechanics and particle physics, spin is an intrinsic form of angular momentum carried by elementary particles, composite particles, and atomic nuclei. Spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum. The orbital angular momentum operator is the quantum-mechanical counterpart to the classical angular momentum of orbital revolution: it arises when a particle executes a rotating or twisting trajectory. The existence of spin angu

The first North Eastern Pacific orca, Wanda, was captured in November 1961 by a collecting crew from Marineland of the Pacific, and over the next 15 years, around 60 or 70 Killer Whales were taken from Pacific waters for this purpose.he majority of orcas on display in the West (USA, Canada, Argentina, Spain, and France), 29 of 38, were born in captivity.
