PENNIS
The nerve cells of cnidarians make up a simple nerve net. This nerve net allows for basic sensory perception and coordination of movements in these organisms.
Yes, they do. They use it to eat.
No, they are from the Phylum Porifera.
their tentacles
Cnidarians, such as jellyfish, use stinging cells called nematocysts for defense and capturing prey. Their locomotion is typically achieved through pulsating movements of their bell or umbrella-shaped body, allowing them to move through the water. Additionally, some cnidarians like corals may remain stationary and rely on water currents to bring food and oxygen to them.
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.
from other animals they get it

small cnidarians and big cnidarians
Mainly through suspension feeding. Cnidarians use stinging tentacles (nomocytes) to capture their prey. Once the tentacles grab the food it is absorbed in the gastrovascular cavity (stomach) and taken in asnutrients.
The cnidarians are in the Kindom family
cnidarians have no nervous system
