EVERYDAY SCIENCE

Detailed explanation-1: -The tentacles, with their stinging cells, serve as defense and as a powerful weapon for capturing prey. When they come into contact with their victims, the nematocysts (cells loaded with poison) present in the tentacles release their harpoons or filaments and release a toxic substance that paralyses the prey.

Detailed explanation-2: -Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. Inside their bell-shaped body is an opening that is its mouth. They eat and discard waste from this opening.

Detailed explanation-3: -No need for a respiratory system: Jellyfish do not have a specialized digestive system, osmoregulatory system, central nervous system, respiratory system, or circulatory system. They are able to digest with the help of the gastrodermis that lines the gastrovascular cavity, where nutrients from their food is absorbed.

Detailed explanation-4: -The white-spotted jellyfish gets its name from the marks adorning its bell. Hanging from that bell, you can see the long, thin tentacles of the jelly fish. These body parts are often lined with structures known as nematocysts, which deliver the jelly’s signature sting.

Detailed explanation-5: -Jellyfish are sea creatures that live in all of the world’s oceans. They have soft, bell-shaped bodies with lengthy, finger-like structures called tentacles. Jellyfish have stinging cells called nematocysts inside of their tentacles. A single tentacle may contain thousands of nematocysts.
