What are nematocycts?

Answer 1

s a type of venomous cell unique to the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.). The cnidocyte cell provides a means for them to catch prey and defend themselves from predators. Despite being morphologically simple lacking a skeleton and usually being sessile, cnidarians prey on fish and crustaceans. A cnidocyte fires a structure that contains the toxin, from a characteristic sub-cellular organelle called a cnidocyst (also known as a cnida or nematocyst). This is responsible for the stings delivered by jellyfish. s a type of venomous cell unique to the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.).

Answer 2

Nematocysts are specialized stinging cells found in the tentacles of cnidarians such as jellyfish and corals. They are used for defense and prey capture by injecting toxins into their target. The discharge of nematocysts can cause a painful sting in humans.

Answer 3

Nematocysts develop on the tentacles of many genus of the phylum Cnidaria, which includes hydras, jellyfish, Portuguese man-of-war, and sea anemones. Each nematocyst has a coiled tubule that shoots out at high speed. Some tubules wrap around prey, some stick to prey, and others contain poison that can paralyze or kill prey.
