Nassarius succinctus is a species of sea snail, a marine gastropod mollusk in the family Nassariidae. This species is commonly found in the intertidal zone and shallow subtidal areas, contributing to the biodiversity of these coastal ecosystems.
Description & Characteristics
Nassarius succinctus typically measures up to 20 millimeters in length. The shell is characterized by a distinctive, conical shape with a pointed apex and a wide aperture. Its surface exhibits fine spiral ridges and axial cords, giving it a slightly rough texture. The color of the shell can vary, ranging from shades of brown, gray, and white. The shell is also often decorated with brown or reddish-brown markings.
Habitat and Occurrence
Nassarius succinctus is a common inhabitant of intertidal zones and shallow subtidal areas, primarily within the infralittoral zone, which extends from the low tide mark down to depths of approximately 50 meters. The species is often found in sandy or muddy sediments, where it can burrow and hide from predators. Its distribution is typically concentrated along the coastlines of the northeastern Atlantic Ocean, with particular abundance in areas such as the British Isles and the North Sea.
Taxonomy
Nassarius succinctus belongs to the family Nassariidae, a group of predatory sea snails that are characterized by their pointed shells and often have a distinctive “snout” or proboscis. The Nassariidae are classified within the Order Neogastropoda, which comprises a diverse group of predatory and scavenging gastropods. The family, order, and class, Gastropoda, all belong to the phylum Mollusca, which encompasses a wide variety of invertebrates, including snails, slugs, clams, and octopuses.
Feeding
Nassarius succinctus is a carnivorous scavenger, feeding primarily on dead or decaying organisms. It uses its proboscis to locate and consume its prey, often searching through the sediment for buried food sources. Its diet includes a wide range of invertebrates, including worms, crustaceans, and other mollusks.
