Gobiinae

life science Maturity 11-13 Next article →

True gobies are a special group of small fish called Gobiinae. They are part of a larger family named Gobiidae. These fish live in almost every ocean on Earth. You can also find some species in lakes or rivers. Most of them like to live in warm waters. There are about 1,149 different kinds of these fish described so far. They belong to 160 different genera.

Many gobies have very interesting ways of moving and living. Most of these fish are small or mid-sized. Their bodies have two dorsal fins on their backs. The first fin has hard, spiny rays. The second fin has many soft rays. Some gobies have pelvic fins that grow together. This creates a suction cup to help them hold onto the ground. They use this to stay in place on the bottom of the water.

These fish come in many different sizes. The largest kind is named Glossogobius giuris. It can grow up to 33 centimeters long. On the other side, some are very tiny. A fish called Trimma nanus is only about 1 centimeter long. This makes it one of the smallest vertebrates in the world. A vertebrate is an animal that has a backbone.

Most adult gobies are benthic. This means they live near the bottom of the water. They often live in a small hole or a crack. Many of them are territorial, so they guard their space. Some gobies even live with other animals like crustaceans. This is called a symbiosis, where different animals live together. Only one kind, Sufflogobius bibarbatus, spends its whole life swimming in open water.

Humans interact with gobies in several ways. Some larger species are caught to be used for food. Many people also keep them in aquariums as pets. They are popular because they are colorful and have bold habits. However, they can be hard to care for at home. They are carnivorous, which means they must eat living food. Some species are also becoming rare because of overfishing.
