In the blue sea sharks are always symbiotic on other spieces
There is genetic variation in the sea stars as a result of sexual reproduction.
One example: A sea anemone and hermit crab have a mutual relationship. The sea anemone protects the crab and the crab provides food.
This question is somewhat vague but it sounds like you are asking about symbiotic relationships, the living together of unlike organisms. It can be defined broadly as mutualism where both benefit, parasitic where only the parasite benefits, or commensal, where one benefits and the other is not significantly harmed or benefitted. Others define it more narrowly as strictly as mutualism. Hope this answwers your question.
annelids, worms,lichen, sea stars
They are symbiotic with sea turtles. Often, you will see starfish on sea turtles' backs; the sea turtle provides food, while the starfish are brightly colored and scare off predators.
Well one good but general answer is the relationship between Clown fish and their sea anemones.There are 2 types of symbiotic relationships.First is parasitism: a tick on a dogNext is communalism: a plant growing out of a tree's branch
In kelp forests
Some species of Blennies do live in symbiotic relationships. They are cleaners and will help other sea creature out by cleaning and they offer the blenny food and protection.
sea urchins eat eaten by crabs, sunflower stars, snails, sea otters some birds, some fish and people...
Yes, the Clown Fish lives within the Sea Anemone getting protection from it's tentacles.
sea turtles have friendly relationships with other sea turtle species, and frock
COMMENSALISM as the crab benefits as the sea anemone provides it with protection but the sea anemone doesn't benefits nor is harmed by the crab
The sea anemone can be found on the sea floor in relatively shallow water. They stay mostly where sunlight still reaches, as they often form symbiotic relationships with algae, who need the sunlight.
There are several animals that eat sea urchins. Sea otters, sunflower stars, snails, crabs and some species of fish predate upon sea urchins.
the sunflower sea star
The relationship between the Sea Gulls and turtle is the predator and the prey relationship as a seagull eats the turtle's eggs and youngs
