what does it feed on?
Symbiotic algae
Cnidaria
Cnidarians feed in several ways: predation, absorbing dissolved organic chemicals, filtering food particles out of the water, obtaining nutrients from symbiotic algae within their cells, and parasitism. Most obtain the majority of their food from predation but some, including the corals "Hetroxenia" and "Leptogorgia", depend almost completely on their endosymbionts and on absorbing dissolved nutrients. Cnidaria give their symbiotic algae carbon dioxide, some nutrients, a place in the sun and protection against predators.
what are the 5 main features of cnidarians Cells bound by inter-cell connections and carpet-like basement membranes; muscles; nervous systems; and some have sensory organs. what type of specimen is this? It is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments anything notable about its skeletal system? In medusae the only supporting structure is the mesoglea. "Hydra" and most sea anemones close their mouths when they are not feeding, and the water in the digestive cavity then acts as a hydrostatic skeleton, rather like a water-filled balloon

Cnidaria [SEP] Feeding and excretion
Cnidarians feed in several ways: predation, absorbing dissolved organic chemicals, filtering food particles out of the water, obtaining nutrients from symbiotic algae within their cells, and parasitism. Most obtain the majority of their food from predation but some, including the corals "Hetroxenia" and "Leptogorgia", depend almost completely on their endosymbionts and on absorbing dissolved nutrients. Cnidaria give their symbiotic algae carbon dioxide, some nutrients, a place in the sun and protection against predators. Predatory species use their cnidocytes to poison or entangle prey, and those with venomous nematocysts may start digestion by injecting digestive enzymes. The "smell" of fluids from wounded prey makes the tentacles fold inwards and wipe the prey off into the mouth.
