Dekeyseria amazonica facts for kids

Dekeyseria amazonica is a special type of armored catfish. It lives only in Brazil, in the huge Solimões and Amazon basins. When an animal is found naturally only in one specific place, we say it is endemic to that area. This fish can grow to about 17.8 centimeters (7 inches) long. That's about the length of a regular pencil!

What is an Armored Catfish?

Fish with Natural Armor

Dekeyseria amazonica is part of a family of fish called Loricariidae. These fish are often called "armored catfish" because they have special bony plates on their bodies. These plates act like natural armor. This armor helps to protect them from predators. It also helps them survive in their river homes.

Where Do They Live?

Most armored catfish, including Dekeyseria amazonica, live in freshwater rivers and streams. They are often found in fast-moving waters. They use their special mouths to cling to rocks and logs. This helps them stay in place even with strong currents.

Life in the Amazon Basin

Home Sweet Home

The Amazon basin is one of the largest river systems in the world. It is a huge and diverse place. It is home to millions of different plants and animals. The Solimões River is a major part of the Amazon River. This is where Dekeyseria amazonica makes its home.

What Do They Eat?

Armored catfish like Dekeyseria amazonica are usually bottom-feeders. This means they spend their time near the riverbed. They often eat algae and tiny bits of plants. They use their unique mouths to scrape food off rocks and submerged wood. This helps keep the river clean!

How Big Do They Get?

As mentioned, Dekeyseria amazonica can reach about 17.8 centimeters in length. This measurement is called "SL" or Standard Length. It means the length of the fish from its snout to the base of its tail fin. While some catfish can grow very large, Dekeyseria amazonica is a medium-sized species.

Why Are They Important?

Part of the Ecosystem

Every animal plays a role in its environment. Armored catfish help keep their habitats healthy. By eating algae, they help control its growth. This keeps the water clearer for other animals. They are also a food source for larger fish and other predators.

Discovering New Species

Scientists are still discovering new species in places like the Amazon. Dekeyseria amazonica was first described in 1985. This means it was officially named and studied by scientists in that year. Discovering new species helps us understand the amazing variety of life on Earth. It also helps us protect these unique creatures.
