Gnathophausia ingens the giant red mysid is a species of lophogastrid crustacean with a pan-tropical distribution. The adults may reach 350 millimetres (14 in) long including the rostrum. Females may brood their young for up to 530 days. Brooding females live between 900 and 1400 m (3000 and 4600 ft) in the eastern Pacific Ocean off California. They do not feed during this time. When they feed they prey on smaller crustaceans.
