Question

Facts about jellyfish..​

Answer 1

Answer:

Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria.

Explanation:

Some jellyfish are clear, but others are in vibrant colors such as pink, yellow, blue, and purple, and often are luminescent. The Chinese have fished jellyfish for 1,700 years.

Jellyfish have a stalked (polyp) phase, when they are attached to coastal reefs, and a jellyfish (medusa) phase, when they float among the plankton. The medusa is the reproductive stage; their eggs are fertilised internally and develop into free-swimming planula larvae.

Jellyfish can be found in all ocean waters.

Because jellyfish tend to just follow the currents of the ocean, they can be found around the world in every type of ocean water. They can thrive in warm tropical water or cold Arctic water. They've been found at the bottom of the ocean and near the surface.
