Q:

What is an example of parasitism in the marine biome?

A:

One common example of a parasite in the marine biome, according to the California Department of Fish and Wildlife, is the larval round worm. The marine biome contains a huge range of parasites, which are living organisms that use another living organism as a host to complete their life cycles.

The larval round worm is a common parasite of fish within the marine biome. The California Department of Fish and Wildlife describes how these parasites live in the intestines, liver, body cavities and flesh of marine fish. Because these parasites can also use humans as hosts, the Department of Fish and Wildlife recommends removing any visible larvae and thoroughly cooking fish before eating them. If fish is being served raw, it is advisable to freeze it for at least 24 hours at -4 degrees Fahrenheit.

Another example of parasitism in the marine biome, according to Phys.org, is Phronima, a tiny creature that uses salps, a species of zooplankton, as their hosts. Phys.org states that Phronima burrow into the centre of the salps, creating a living barrel, in which the Phronima live, raising their young and eating food that floats by. These parasitic creatures were the inspiration behind the hair-raising xenomorph of the "Alien" films.

The Marine Bio Conservation Society states that some parasitic crustaceans in the marine biome, such as many isopods, latch themselves to a host without causing actual harm to the host.

    How do starfish eat?

    A:

    A starfish eats by wrapping its arms around a bivalve's shell, prying it open, injecting its stomach into the shell and then digesting the prey. After digesting, it slides the stomach back into its body. This allows the starfish to eat food that cannot fit through its tiny mouth.
