GIANT RED MYSID (Gnathophausia ingens): SPECIES ACCOUNT

Lophogastrids live in all oceans except the Arctic. Most species are found in the Pacific and Indian oceans.


Lophogastrids usually swim in deep, open waters down to depths of 3,280 feet (1,000 meters). Some species are found in waters as shallow as 164 feet (50 meters).


Most lophogastrids are thought to be predators. They prey on free-floating animals called zooplankton. Only one species, Gnathophausia, seems to use its bristly mouthparts as filters to strain large particles of food from the water.


No lophogastrids are considered endangered or threatened.
