Antalis pilsbryi is a species of tusk shell, a type of marine mollusk belonging to the class Scaphopoda. These intriguing creatures, also known as tooth shells, are characterized by their elongated, tubular shells that resemble miniature elephant tusks. Antalis pilsbryi is a relatively common species with a distinct distribution pattern.
Description & Characteristics
Antalis pilsbryi has a slender, elongated shell that can reach a maximum size of approximately 40 millimeters in length. The shell is typically white or cream-colored, with a slightly curved shape that tapers towards the narrower end. The opening at the wider end of the shell is known as the aperture, and it serves as the animal’s mouth. The smaller, pointed end of the shell is called the apex, and it is where the animal’s foot emerges.
Habitat and Occurrence
Antalis pilsbryi is a marine species that prefers to live in sandy or muddy substrates. It can be found in both shallow and deeper waters, with a typical depth range of 10 to 100 meters. Antalis pilsbryi is often found in the infralittoral zone, which extends from the low tide mark to the edge of the continental shelf. This zone encompasses a variety of habitats, including sandy beaches, rocky shores, and seagrass meadows. Antalis pilsbryi‘s presence in these ecosystems contributes to the diversity and ecological balance of the marine environment.
Taxonomy
Antalis pilsbryi is classified within the order Dentaliida and family Dentaliidae, which encompasses a diverse group of tusk shells. These animals belong to the class Scaphopoda, which is a unique group of marine mollusks distinguished by their elongated, tubular shells. The scientific classification of Antalis pilsbryi reflects its evolutionary history and relationships with other species within this intriguing group.
Feeding
Antalis pilsbryi is a suspension feeder, meaning it obtains its food by filtering small organisms and particles from the surrounding water. Its diet consists primarily of plankton, algae, and other microscopic organisms. Antalis pilsbryi uses its long, slender foot to burrow into the sediment, where it extends its tentacles to capture food particles.
