WHAT DO CLAMS EAT?January 18, 2021
Recognizing a clam is not a complicated job, however, it should be noted that bivalves are known by the name of clam, which is nothing other than mollusks that have a shell composed of two laterally arranged valves. The bivalves group more than 13 thousand different species that have different sizes. And many times different forms of construction of their shells, being in most cases marine species.
The place where clams live is usually buried under sand or mud. Where they develop according to the availability of resources around them. And factors such as salinity, temperature, among others. Some species are used by man in a culinary way. Being a highly valued dish in certain markets of the world due to its flavor and characteristic consistency.
CHARACTERISTICS OF CLAMS
Clams have a flattened and soft body that is covered or protected with two strong and hard shells. The way this animal buries its body in the sand is thanks to a muscular foot and is, in the same way, the way they move clams. Its respiration is carried out by means of two gills that are arranged in the region of the head.
The way in which clams reproduce is often a question for many people, however, it is not a complicated process; It must first be clarified that clams are unisexual animals so that males and females can be found separately, this would lead to thinking that it complicates reproduction a bit, so clams tend to release their sex cells in the water, they are fertilized by the sex cells of other clams. After this process, the veliger’s are born, which after growing as larvae look for sand or mud to bury themselves and begin their metamorphosis process to become an adult clam.
WHAT DO CLAMS EAT?
Clams are fed simply but very efficiently. Talking about what clams eat freshwater clams or river clams is not far from the feeding of sea clams. Since all of them feed on organic remains that are suspended in the water.
The process of feeding the clams is possible by filtering the water, this means that the clams, after being attached to rocks or buried in the sand or mud, begin the process of sucking and expelling water that allows them to become small organic particles such as phytoplankton, zooplankton, detritus, among many others. The availability of these foods determines the speed and how much a clam will grow according to the maximum sizes of its species, and some can be found with a size of 15 decimeters.
It should be noted that some species of clams are parasitic. And it is not uncommon to find them living on some sea urchins, starfish. And certain crustaceans where it is easier for them to obtain food.
