Cadulus teliger, commonly known as the Tusk Shell, is a species of marine mollusk belonging to the class Scaphopoda, order Gadilida, and family Gadilidae. These small, slender creatures are found in a variety of marine environments, showcasing a fascinating adaptation to their unique lifestyle.
Description & Characteristics
The Tusk Shell, as its name suggests, has a distinctive elongated, tusk-like shell. Its cylindrical shape tapers towards both ends, with a slightly wider, open end that serves as the mouth. The shell is typically white or pale brown, often exhibiting a smooth, glossy surface. Cadulus teliger reaches a maximum size of about 15 mm, making it a relatively small species within the Scaphopoda class.
Habitat and Occurrence
Cadulus teliger is a common inhabitant of soft-bottom substrates, particularly sand and mud. These marine invertebrates typically occur in depths ranging from the intertidal zone down to about 100 meters, making them a prevalent presence in the neritic zone. They are often found in association with other benthic invertebrates, such as polychaete worms and crustaceans.
Taxonomy
The species Cadulus teliger is classified within the Class Scaphopoda, which comprises a group of marine mollusks characterized by their elongated, tusk-like shells. This class falls within the Order Gadilida, which encompasses a diverse range of scaphopods, and within the Family Gadilidae, a group known for their slender, often pointed shells.
Feeding
Cadulus teliger is a detritivore, meaning it feeds primarily on organic matter, such as decaying plant and animal debris, found within its environment. These microscopic food particles are extracted from the sediment using specialized tentacles located around the mouth.
