Fishes
Fishes are aquatic animals that live in freshwater or saltwater habitats, from small streams to deep oceans. They come in many shapes and sizes, and they play a major role in ecosystems as predators, prey, and important links in food chains.
What are fishes?
Fishes are vertebrates that usually breathe using gills and move with fins. Most fishes are cold blooded, meaning their body temperature changes with the surrounding water. Some, like sharks and rays, have skeletons made of cartilage, while many others have bony skeletons.
Types of fishes
Students can group fishes in different ways, such as by body structure, habitat, and survival features. Here are a few simple types you will often see while learning about fishes.
- Bony fishes: Common fishes with a hard skeleton made of bone, such as tuna and cod.
- Cartilaginous fishes: Fishes with a skeleton made of cartilage, such as sharks and ray fish.
- Deep sea fishes: Fishes adapted to low light and high pressure conditions, such as dragonfish.
- Freshwater fishes: Fishes found in rivers and lakes, such as carp fish and mahseer.
