Question

How do cnidarians differ from sponges?

Answer 1

cnidarians consist of jellyfish, hydra,. they differ from sponges (porifera) based on their complexity.

Sponges (Porifera) are the simplest members of the Kingdom Animalia. They have no bones, no organs, no muscles, no nervous system, and they have a one way digestive tract. they get nutrition by ingesting microorganisms through a small mouth opening called an Osculum.

Cnidarians are much more complex. They have muscles, they have a complex nervous system, and they have several adaptations for catching food, the most notable being tiny structures on the tentacles called Cnidocytes.

When a fish or other small animal touches the tentacles of a cnidarians, the cnidocytes on the tentacles send out tiny "harpoons" called Neumatocysts, which penetrate the skin of the victim and release toxins which can paralyze or kill the prey.
