Most bivalves have a large foot, which is a muscular and expandable structure in the middle of the mantle cavity. The foot primarily functions as a burrowing organ in infaunal species. It can also …

The bivalve foot, unlike that of gastropods, does not have a flat creeping sole but is bladelike (laterally compressed) and pointed for digging. The muscles mainly responsible for movement …

Bivalves have bilaterally symmetrical and laterally flattened bodies, with a blade-shaped foot, vestigial head and no radula. [9][10] At the dorsal or back region of the shell is the hinge point …

In most bivalves, the foot is laterally compressed and blade-like, and the anterior part of the foot acts as a burrowing organ in the soft substratum where they live. Mechanism of burrowing: …

Aug 26, 2020 · All bivalves possess a large muscular foot. Most bivalves have two tubes, or siphons, located toward the posterior end of the animal. These are called the incurrent siphon …

A triangular form, ventral flattening, and secure attachment to firm substrates by byssal threads (byssus; proteinaceous threads secreted by a gland on the foot) have allowed certain bivalves …

The bivalve foot, unlike that of gastropods, does not have a flat creeping sole but is bladelike (laterally compressed) and pointed for digging. The muscles mainly responsible for movement …

• Bivalves like Anodonta and Unio have a laterally compressed triangular and ploughshare like or hatchet shaped muscular foot for crawling and ploughing through mud. • Foot is actually the …

The sessile bivalves, such as the oyster and jingle shells (Anomia), have a greatly reduced foot. Scallops also have a reduced foot and swim in jerky, but often quite effective in the short run, …

Jan 26, 2001 · A bivalve uses its muscular foot either to attach itself to a substrate or to burrow. Scallops propel themselves through the water by jet propulsion: rapid closing of the valves …
