GEOGRAPHIC RANGE
Lophogastrids live in all oceans except the Arctic. Most species are found in the Pacific and Indian oceans.
HABITAT
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).
DIET
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.
CONSERVATION STATUS
No lophogastrids are considered endangered or threatened.
