Chama echinata is a species of marine bivalve mollusc that is commonly known as the “spiny jewel box”. It is a striking and fascinating creature that is known for its distinctive appearance and unique biology.
Description and Characteristics
Chama echinata is a medium-sized bivalve, typically reaching a maximum size of around 10 centimeters in length. It has a thick, heavy shell that is covered in numerous spines, giving it a spiky and somewhat intimidating appearance. These spines are actually a defense mechanism, helping to protect the mollusc from predators. The shell of Chama echinata is also highly variable in color, ranging from shades of white and cream to pink, orange, and even purple.
Habitat and Occurrence
Chama echinata is a common inhabitant of coral reefs and rocky shores in tropical and subtropical waters. It typically occurs in shallow water, often attached to hard substrates such as rocks, corals, or even the shells of other molluscs. Chama echinata is a relatively sedentary species, meaning that it tends to stay in one place for extended periods of time. Its distribution is widespread, ranging from the Caribbean Sea to the western Atlantic Ocean.
Chama echinata is typically found in the neritic zone, which is the shallow water region of the ocean that extends from the shoreline to the edge of the continental shelf. This zone is characterized by its relatively warm temperatures, high levels of sunlight, and abundance of nutrients, providing an ideal habitat for this species.
Taxonomy
Chama echinata belongs to the Class Bivalvia, which is a large and diverse group of molluscs that includes clams, oysters, and mussels. It is classified within the Order Venerida, which is a group of bivalves that are characterized by their siphons, which are tubes that allow them to draw water into their bodies. Finally, Chama echinata belongs to the Family Chamidae, a group of bivalves that are known for their thick, heavy shells and their tendency to attach themselves to hard surfaces.
Feeding
Chama echinata is a filter feeder, meaning that it obtains its food by filtering microscopic organisms from the water column. It does this by drawing water into its body through its siphons, filtering out the food particles, and then expelling the filtered water back out. Chama echinata is an important part of the marine ecosystem, playing a role in maintaining water quality and serving as a food source for a variety of other organisms.
