The wild Goldfish are omnivores and eat plants, insects (such as mosquito larvae), zooplankton, detritus and small crustaceans. Other species are able to survive in wider temperature ranges. Characters of mammals are same in all classes. Fishes are cold-blooded and they can't control their body temperature.

A fish's body temperature fluctuates according to the water's temperature around them. The general purpose of fins is to provide motion, maneuverability, and stability. Jellyfish are free-swimming marine animals composed of more than 95 percent water, with bodies consisting of an umbrella-shaped bell and trailing tentacles.
