Jabuti: example of terrestrial turtle

What they are - biological meaning

Belonging to the Chelonia order and also known as testudines, turtles are reptiles that have a carapace. There are currently cataloged about 300 species of turtles in the world. They inhabit mainly regions with large presence of rivers, lakes, seas and tropical forests.

Summary of main features:

- They have dorsal carapace, which originates from the fusion of dermal bone plates. This hard and resistant carapace has as its main function to ensure the protection of the body of turtles against predators and physical impacts.

- In addition to carapace, turtles have the protection of a rigid ventral plastron.

- Chelonian vertebrae and ribs are fused to the plastron and carapace.

- The turtles are oviparous animals.

- They have no teeth in the mouth. Foods are cut and pulled through the use of horny blades.

Examples of turtles:

- Freshwater and sea turtles

- Jabutis (live in the land)

- Tortoises (live in freshwater environments)


- Sea turtles feed mainly on mollusks, mussels and crabs.

- Terrestrial turtles (jabutis) eat fruits, vegetables, insects, worms and even mice.

- Turtles (freshwater turtles) feed on fish, riverbank plants, fruits that fall into rivers, insects and mollusks.
