Cnidarians have a simple body plan with a sac-like structure composed of three layers of cells: the epidermis, the gastrodermis, and the mesoglea. They possess specialized cells called cnidocytes that contain stinging structures called nematocysts, used for defense and capturing prey. Cnidarians also have a simple nerve net for coordinating movements and responses.

What are the Genus and Species of Cnidarians?
There is no single genus or species. Cnidarians make up an entire phylum within which there are thousands of genera and species.
All cnidarians possess long extensions of the body called tentacles?
True, tentacles are a common feature among cnidarians like jellyfish and sea anemones. These structures are typically armed with stinging cells called cnidocytes, which help cnidarians capture prey and defend against predators. Tentacles are used for a variety of functions including feeding, sensing the environment, and locomotion.

What are cnidarians most common predators?
Common predators of cnidarians include sea turtles, fish such as triggerfish and butterflyfish, crustaceans like crabs, and certain species of snails and sea stars. Some marine birds also feed on cnidarians.
Are organs present in cnidarians?
no
What organs are involved with the excretory system in phylum cnidarian?
In the phylum Cnidaria, such as jellyfish and sea anemones, the gastrovascular cavity functions as both a digestive and excretory system. Waste and excess materials are expelled through the mouth or diffused out of the cells lining the cavity. Cnidarians do not have specialized excretory organs like kidneys.
What anima doesn't have a skeleton or a exoskeleton?

What are two types of cnidarians that are formed by colonies?
small cnidarians and big cnidarians
What is cnidarians excretion?
Cnidarians, such as jellyfish and corals, excrete waste primarily through diffusion across their body surface. They do not have specialized excretory organs like kidneys. Waste products, such as ammonia, are released into the surrounding water through their skin and tentacles.
Do cnidarians have nerves?

How do sponges and cnidarians obtain food and what do they eat?
Cnidarians have strings to get their food also to get protection they are also divided in three groups what they also have that sponges dont is string cells and they have a simple nervous system . On the other hand,Sponges have No symmetry they never move and have no organs . Thanks for using my answers to help you with your science work .
