Sulahavaru

Sulahavaru is a genus of marine mollusks belonging to the family Nuculidae. These bivalve clams are characterized by their relatively small, ovate shells, which are typically equivalve and inequilateral. The shell surface is usually smooth or finely sculptured with concentric growth lines. Internally, the hinge line is typically arched, featuring a series of small, interlocking teeth. The periostracum, a thin organic layer covering the shell, is often prominent and can be eroded in older specimens.

These bivalves are found in marine environments worldwide, inhabiting sandy or muddy substrates in both shallow and deep waters. They are deposit feeders, using their siphons to draw in detritus and other organic matter from the seafloor. Reproduction is typically sexual, with external fertilization. The larvae are planktonic before settling to the benthos to develop into juvenile clams. Sulahavaru species play a role in benthic ecosystems by processing organic matter and serving as a food source for various predators. Fossil records indicate the presence of this genus extending back to the Mesozoic era.
