found nucleus organisms
Tusk shells are found in cool and warm water oceans worldwide, from seashores to depths down to about 23,000 feet (7,000 meters).
Tusk shells are found only in soft, muddy ocean bottoms where they burrow to search for food.
Tusk shells eat microscopic organisms, especially foraminiferans (fo-re-mi-NIH-fer-ehns), single-celled organisms that have a nucleus. The nucleus is a structure that contains the genetic information. Other species feed on tiny crustaceans, as well as clams and their relatives.
No species of scaphopod is considered threatened or endangered.
