Razor shell

Razor shell is a common name for a variety of bivalve mollusks that have a long, narrow, and rectangular shape, similar to a straight razor. The term is often used to refer to species within the family Solenidae, but can also include species from the family Pharidae.

Description

Razor shells are characterized by their elongated, narrow shape and sharp edges. They have a pair of equal-sized shells that are joined at one end by a flexible hinge. The shells are typically smooth and shiny, with a color that ranges from white to yellowish-brown.

The interior of the shell is lined with a soft, fleshy body that includes a foot for burrowing into the sand, and a pair of siphons for filtering food particles out of the water.

Habitat and Distribution

Razor shells are found in marine environments worldwide, from the intertidal zone to depths of several hundred meters. They prefer sandy or muddy substrates, where they can burrow to hide from predators and to filter feed.

Human Use

Razor shells are harvested in many parts of the world for their meat, which is considered a delicacy. They are often collected by hand or by using a rake to dig them out of the sand. In some regions, they are also farmed in aquaculture operations.

Conservation

While many species of razor shells are abundant, some are threatened by overharvesting, habitat loss, and pollution. Conservation efforts for these species typically involve regulations on harvesting and efforts to protect and restore their habitats.
