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.
What is an example of competition in the coral reef?
Additional examples of competitive relationships in a coral reef include spatial competition between different species of corals such as elkhorn coral and staghorn coral as well as competition for prey between fish species like butterflyfish and damselfish.
What is the common name for cnidaria?
jellyfish
cnidarian, also called coelenterate, any member of the phylum Cnidaria (Coelenterata), a group made up of more than 9,000 living species. Mostly marine animals, the cnidarians include the corals, hydras, jellyfish, Portuguese men-of-war, sea anemones, sea pens, sea whips, and sea fans.
What kind of symbiotic relationship do zooxanthellae and corals have?
Coral polyps, which are animals, and zooxanthellae, the plant cells that live within them, have a mutualistic relationship. Coral polyps produce carbon dioxide and water as byproducts of cellular respiration. The zooxanthellae cells use carbon dioxide and water to carry out photosynthesis. Learn more.
Why are corals in the phylum Cnidaria?
Corals, anemones and jellies are related and all classified in the phylum Cnidaria or “stinging needles.” The animals in this group are aquatic, possess stinging cells within their tissues and have a body plan characterized by radial symmetry, which allows all parts of their bodies to be equally receptive and …
What eats clownfish in the Great Barrier Reef?
Even though anemone provides protection against predators, clownfish is often preyed by large fish, eels and sharks.
What are some predators in the coral reef?
In addition to weather, corals are vulnerable to predation. Fish, marine worms, barnacles, crabs, snails and sea stars all prey on the soft inner tissues of coral polyps. In extreme cases, entire reefs can be devastated if predator populations become too high.
What nutrients do zooxanthellae need?
Zooxanthellae are photosynthetic algae that use light as an energy source. They metabolize Carbon Dioxide, Nitrogen, and Phosphorus, which are waste products from the coral. In return, the Zooxanthellae provide the coral with their photosynthetic by-products, all of which are coral nutrients: Carbohydrates.
What are zooxanthellae quizlet?
Zooxanthellae are producers that make their own food and therefore they carry out photosynthesis, The zooxanthellae gives the coral its color and oxygen. They help the coral reef form their exoskeleton. The relationship between the zooxanthellae and polyps are symbiosis or Mutualism.
Which class belongs to the phylum Coelenterata?
Coelenterates are classified into three different classes: Anthozoa. Hydrozoa. Scyphozoa.

What are the three phyla of the Coelenterata?
Hatschek (1888) splitted Leuckart’s Coelenterata into three distinct phyla – Spongiaria (Porifera), Cnidaria (Coelenterata) and Ctenophora. The coelenterates or cnidaria are distinguished from sponges in being “tissue animals” (Metazoa) that have distinct digestive cavity.
Are there sponges in the Coelenterata of Leuckart?
However, the Coelenterata of Leuckart also included the sponges and ctenophores. Hatschek (1888) splitted Leuckart’s Coelenterata into three distinct phyla – Spongiaria (Porifera), Cnidaria (Coelenterata) and Ctenophora.
When was the animal nature of coelenterata established?
The animal nature of coelenterates was established by Peyssonel (1723) and Trembley (1744). Linnaeus, Lamarck and Cuvier grouped the coelenterates under Radiata which included the echinoderms also because of their symmetry.
