This kind of interaction between an invertebrate and a photosynthetic partner is abundantly found in marine ecosystem. The best example of such an interaction is seen between members of the phylum Cnidaria (e.g., hard and soft corals, sea anemones and jellyfish) and dinoflagellate algae.

What is cnidarian mutualism?
The relationship between cnidarians and dinoflagellate algae is termed as "symbiotic", because both the animal host and the algae are benefiting from the association. It is a mutualistic interaction. For some cnidarian species, it has been studied whether or not they could even survive without the dinoflagellate algae.
How do cnidarians interact with other animals?
Both polyp and medusa forms feed on a wide variety of microorganisms and animals. Polyp feeding is somewhat passive and dependent on water currents to bring prey into close proximity. ... They feed on small invertebrates and, like many other polyp forms of cnidarians, they form symbiotic relationships with algae.
What are 3 examples of a cnidarian?
Mostly marine animals, the cnidarians include the corals, hydras, jellyfish, Portuguese men-of-war, sea anemones, sea pens, sea whips, and sea fans.
What is mutualism in science?
mutualism, association between organisms of two different species in which each benefits. Mutualistic arrangements are most likely to develop between organisms with widely different living requirements.
Are Cnidaria photosynthetic?
Animals acquire photosynthetically-fixed carbon by forming symbioses with algae and cyanobacteria. These associations are widespread in the phyla Porifera (sponges) and Cnidaria (corals, sea anemones etc.) ... Photosynthetic products are released from living symbiont cells to the animal host at substantial rates.
Is Coral a cnidarian?
Cnidarians are soft-bodied animals that include corals, jellyfish, and sea anemones. These soft-bodied animals have saclike digestive cavities and tentacles containing rows or stinging cells used for defense and capture of food.
Are starfish cnidarians?
The phylum Cnidaria (pronounced nid-AIR-ee-ah) contains approximately 9000 living species worldwide. ... A common example of radial symmetry is the sea star (a member of the Echinoderm phylum) or the anemone, a Cnidarian (seen below). The Cnidarians include the hydroids, jellyfish, anemones, and corals.
Are sexes separate in cnidaria?
Cnidarians have separate sexes and have a lifecycle that involves morphologically distinct forms. These animals also show two distinct morphological forms—medusoid and polypoid—at various stages in their lifecycle.
Are jellyfish Detritivorous?
Jellyfish are like other cnidarians generally carnivorous (or parasitic), feeding on planktonic organisms, crustaceans, small fish, fish eggs and larvae, and other jellyfish, ingesting food and voiding undigested waste through the mouth.
How do you say phylum Cnidaria?
phy·lum Cnidari·a.
Are cnidarians Colonial?
Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors.
Do Cnidaria have appendages?
Yes, some the members of the Cnidaria phylum have appendages.
