Рассказ о морском животном на британском

Jellyfish are unique marine animals that can live seas and oceans.
The bodies of most jellyfish are almost invisible as they consist of water at 97 percent. Jellyfish have a variety of colors and shapes. Their sizes can be from a few millimeters to two and a half meters, and their tentacles sometimes reach 30 meters in length. They can be found both on the surface of the sea and in great depths. Most jellyfish are very beautiful, they seem to be creatures that are not able to offend. However, jellyfish are active predators. On their tentacles there are special capsules that can paralyze a prey. Some jellyfish are quite safe, others are dangerous.
