jellyfish have no bones, exoskeleton, or shell to protect or support them. The jellyfish is considered simple-bodied because, like its Cnidarian cousins, it has no head, brain, heart, eyes, or ears. Thus it is also lacking in the sensory systems that correspond to these organs.

Stinging structures of jellyfish are?
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
What is a stinging cell on a tentacle of a jellyfish?
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
What are the stinging cells located on the tentacles of a jellyfish?
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
What is the name of the animal which is shaped like an umbrella and has sting cells?
The animal you are referring to is a jellyfish. Jellyfish have a bell-shaped body that resembles an umbrella and possess specialized cells called cnidocytes that contain stinging structures used for defense and capturing prey.
What are stinging cells called?
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
What is the cell some animals only have?
Some animals, particularly certain types of sponges and jellyfish, primarily have specialized cells rather than true tissues or organs. For example, sponges possess unique cells called choanocytes, which help in feeding and water flow. Jellyfish have cnidocytes, specialized cells that contain stinging structures used for capturing prey. These specialized cells allow these animals to perform essential functions despite their simple body structures.
What is the structures of jellyfish for food getting?

What is the proper phylum for a jellyfish?
Jellyfish belong to the phylum Cnidaria. This phylum includes other marine animals such as corals and sea anemones, characterized by the presence of specialized cells called cnidocytes, which contain stinging structures. Jellyfish are classified within the class Scyphozoa, although some are also categorized in the class Hydrozoa and Cubozoa.
Why does a jellyfish has tentacles tha sting?
Jellyfish have tentacles that sting primarily for defense and to capture prey. The tentacles contain specialized cells called cnidocytes, which house stinging structures called nematocysts. When triggered, these nematocysts release toxins that can incapacitate small fish and other prey, making it easier for the jellyfish to feed. Additionally, the stinging mechanism helps protect the jellyfish from potential predators.
What are some structures missing from a jellyfish?
A skeleton
What is the jellyfish circulatory system?
Most jellyfish do not have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems.
How do jellyfish catch fish?
Jellyfish catch fish primarily using their tentacles, which are lined with specialized cells called cnidocytes that contain stinging structures called nematocysts. When a fish comes into contact with the jellyfish's tentacles, the nematocysts fire, injecting toxins that paralyze or immobilize the prey. The jellyfish then moves its tentacles to bring the incapacitated fish to its mouth for consumption. This method allows jellyfish to capture prey effectively, despite their passive drifting nature in the water.
