Fish

Quck answer

Fish are aquatic animals that have adapted to live in a wide variety of environments, from the freezing depths of the ocean to shallow freshwater streams. They are an important part of the global ecosystem, providing food for both humans and other animals. There are over 30,000 species of fish, ranging in size from tiny minnows to massive whalesharks. Many fish are also kept as pets in home aquariums. However, many species of fish are threatened by overfishing, pollution, and habitat destruction, making conservation efforts crucial for their survival.

The underwater creatures commonly known as fish are a diverse group of aquatic animals that breathe through gills and have fins for swimming. They are found in a variety of water bodies, from freshwater streams and rivers to saltwater oceans. Some fish are considered game fish and are sought after by anglers for sport fishing, while others are commercially harvested for food. Fish play an important role in the ecosystem as both predator and prey. Despite their differences in size, shape, and color, all fish share the common characteristic of being cold-blooded vertebrates.
