Sooty crayfish (Pacifastacus nigrescens) has become extinct partly due to interspecific competition with Pacifastacus leniusculus, which was introduced into its range. P. leniusculus has also been implicated in causing a reduction in the range of the already narrowly endemic shasta crayfish (Pacifastacus fortis).
