Is a jellyfish a fish?

ellyfish are fascinating marine animals, known for their distinctive bell-shaped bodies and trailing tentacles. Here's a breakdown of some key facts about them:

Basic Characteristics:

Simple Organisms: Despite their appearance, jellyfish are remarkably simple creatures. They lack brains, hearts, blood, and even bones.
Mostly Water: Their bodies are composed of about 95% water, which gives them their gelatinous texture and allows them to be buoyant.
Radial Symmetry: Their body parts radiate from a central axis, allowing them to detect and respond to food or danger from any direction.
Cnidarians: Jellyfish belong to the phylum Cnidaria, which also includes sea anemones, corals, and hydroids. They are characterized by specialized stinging cells called cnidocytes on their tentacles.
