Coelenterates
74Cnidarians
There are over 90,000 species of coelenterates, which are also known as cnidarians in the world. These cnidarians are invertebrates, meaning they have no back bone once so ever. These invertebrates live in the fresh waters of the beautiful ocean. But what exactly are cnidarians? Where do they live and how do they survive or reproduce?
Coelenterates (cnidarians) are animals that have tentacles surrounding their mouth. The tentacles contain stinging cells that make it easy to capture their next meal, and contain poison to kill their prey. Some of the animals that are cnidarians are jellyfish, octopus, corals, hydra, sea fans, and sea anemones.
Cnidarians bodies have two layers of cells. The outer layer of cells covers the body while the inner layer lines the digestive system, which is where the food is broken up to be made into both energy and nutrients. The body can either have the shape of an umbrella, a bell, or a cylinder. The body also comes in any of these three colors: red, white, or green. Their bodies contain a nervous system, and contain sensory organs. It also has a muscular skeleton.
Cnidarians use their environment to obtain or get oxygen to stay alive. They get rid of waste through their mouth since it has no anus. It has radical symmetry; it eats both animals and plants. These types of species can produce both sexually and asexually. It reproduces sexually by releasing either sperm or egg into the water. Cnidarians produce asexually by budding.
This is how cnidarians reproduce, and how they live. This is also how cnidarians survive in the never ending ocean. Cnidarians are very unique creatures that are more than meets the eye.
