commensalism
Barnacles on a crab's shell improve its toughness, while the barnacles (normally lacking motility) are able to visit more than one location to obtain food, and may even feed on the crab's prey. Some barnacles, however, can cause damage or sterility in some species of crabs.
They aren't symbiotic : the barnacles (crustaceans related to crabs) are parasites on the whale's skin, and will also attach to boats, docks, and other marine locations.
They won't have any shells to live in
Sea cucumbers often share a symbiotic relationship with crabs and shrimp, particularly in terms of habitat and protection. Crabs and shrimp can be found living on or around sea cucumbers, benefiting from the shelter they provide from predators. In return, these small crustaceans help keep the sea cucumbers clean by feeding on parasites and debris on their surface. This mutualism enhances the survival and health of both parties involved.
There is only one main difference between hermit crabs and barnacles. Hermit crabs have a hard exoskeleton that protects their bodies.
one example are whales and barnacles, the barnacle benefits from the whale because it eats and gets protection, and the whale does not seem to be affected in any way.Commensalism is a symbiotic relationship where one party benefits and the other is not harmed. Examples of commensalism in the ocean are barnacles living on turtles, remoras feeding on a shark's food scraps and a crab that makes its home in an oyster's shell.
A sacculina is a genus of barnacles, which is a castrator of crabs.
Both crabs and barnacles have claws and also both shed their external skeleton, the limpets do not.
Five examples of crustaceans: crabs, lobsters, barnacles, shrimps, and krill Barnacles are not a crustacean.
becaus is awsome
Blue crabs usually eat clams, oysters, and mussels though they prefer freshly dead or freshly caught food. They do not eat barnacles but they are often found on the crab.
Barnacles get stuck on crabs primarily because they are opportunistic filter feeders that attach themselves to hard surfaces, including the shells of crabs, to benefit from the constant flow of water and food particles. This relationship can be advantageous for barnacles, as it allows them to access nutrient-rich environments. However, it can be detrimental to the crab, as heavy barnacle infestations may hinder its mobility and overall health.
