Detailed explanation-1: -Body Forms Sea anemones are examples of the polyp forms, while jellyfish are examples of the medusa forms.
Detailed explanation-2: -Jellyfish, anemones, corals and hydroids are collectively known as cnidarians (Ancient Greek: knide = nettle, named after a type of plant with stinging hairs). With over 10, 000 known species, they all have soft, hollow bodies, live in water and generally have tentacles.
Detailed explanation-3: -They usually occur in bell-shaped bodies lacking a true head and organs, but they are able to swim or float freely. Cnidarians in the polyp form include coral, hydra, and anemones. Polyps are sessile creatures meaning they are permanently attached to substrate and feed only when prey flows through their tubular bodies.
Detailed explanation-4: -The class Anthozoa (under the phylum Cnidaria) includes corals, anemones, sea pens and seafans. Anthozoa consists of 10 orders and thousands of species. Adults are attached to the seabed, but their larvae are free-floating and can drift to new settlements.
