A Chelonia order is composed of reptiles that have hooves formed by rigid bone plates with a keratinized layer.
We prepared a list of exercises on the Chelonia Order so you can test your knowledge about the group of turtles, tortoises and tortoises.

1) Chelonians can be easily recognized due to a peculiar characteristic. What feature is this?
a) Thick skin.
b) Scales.
c) Skin covered by keratin.
d) Carapace.
e) Flippers.
2) (UECE) Pay attention to the following news: “Professor of the UECE catches the death of 439 turtles in the Cedro dam in Quixadá; research will be carried out to reveal causes… The professor comments that animal mortality can cause an even more serious situation. He predicts that with the first rains, the water that may accumulate could pose risks to public health, since there will be no living species in the dam to fulfill the role of the ecosystem.” (Source: https://blogs.diariodonordeste.com.br/sertaocentral/meioambiente/professor-da-uece-flagra-mortandade-decagados-no-acude-cedro-pesquisa-sera-feita/)
About the chelonians referred to in the news excerpt, it is correct to state that:
a) are represented by tortoises, turtles and tortoises: oviparous animals.
b) are represented by turtles, snakes and tortoises: oviparous animals.
c) tortoises are terrestrial chelonians that have a flattened body and a long neck.
d) tortoises are terrestrial turtles and tortoises are freshwater turtles.
3) (UNICENTRO) Traditionally, we call reptiles a group of animals that have, in common, ectothermia and skin covered by scales. This group includes several lineages (lizards, snakes, amphisbaenians, chelonians and alligators), although some of them are little related to each other. For example, it is known today that alligators are more closely related to birds than to lizards, snakes and turtles, although, in practice, alligators continue to be treated together with these animals, within the group we call reptiles (MONTEIRO, 2008).
Based on the knowledge about this group of vertebrates, it is correct to state:
a) the vast majority of these animals are animals belonging to the base of the trophic chain.
b) excrete mainly urea and ammonia, nitrogenous compound with low toxicity, which needs little water to be eliminated.
c) in the course of evolution, reptiles were the first vertebrates to effectively dominate the terrestrial environment, due to their eggs, that could develop outside the aquatic environment and their circulatory pattern constituted by a heart with four chambers well divided.
d) some reptiles, such as turtles, can remain under water for a few hours, trapping the breathing and, for that, the organism works slowly, the heart beats slowly, in a phenomenon called tachycardia.
e) the digestive system is complete, with well-developed glands, such as the liver and pancreas, ending in the cloaca, and its breathing is strictly pulmonary.
4) All of the following animals are chelonians except:
the turtle.
b) alligator.
c) tortoise.
d) turtle.
e) Tracajá.
5) All of the organisms listed below are examples of vertebrate animals, except:
a) monkey.
b) man.
c) frog.
d) turtle.
e) octopus.
6) The following are part of the Chelonia order:
a) sea turtles, freshwater turtles, tortoises and tortoises.
b) freshwater turtle, manatee, tortoise and tortoise.
c) sea turtles, freshwater turtles, tortoises and snakes.
d) sea turtles, seahorses, tortoises and tortoises.
e) frog, freshwater turtle, tortoise and tortoise.
7) Analyze the alternatives below and mark the one that contains incorrect information about chelonians.
a) All turtles are classified as chelonians.
b) Chelonians have a carapace and plastron.
c) The carapace of chelonians is formed by the fusion of the vertebral column with the ribs.
d) The plastron is the dorsal part of the shell of chelonians.
e) The shell of chelonians acts to protect against predators.
8) What type of food do chelonians have?
a) Omnivore.
b) Vegetarian.
c) carnivore.
d) Vegan.
9) There are about 75 different genera of chelonians, which are distributed in 13 families. The turtle is an example of chelonian and stands out for the presence of a shell consisting of a carapace and a plastron. Mark the alternative that correctly indicates what the plastron is made of.
a) The plastron is formed by the fusion of the ribs and vertebrae.
b) The plastron is formed by the fusion of the femur and tibia.
c) The plastron is formed by the fusion of the clavicle and vertebrae.
d) The plastron is formed by the fusion of the skull and vertebrae.
e) The plastron is formed by the fusion of clavicle, interclavicle, and abdominal ribs.
10) (UFSCar) An animal that has as characteristics the presence of a vertebral column, internal fertilization with copulation, pulmonary respiration, embryo protected by egg with hard shell, mixture of venous and arterial blood and variable temperature with the environment must belong to the group:
a) of birds.
b) of fish.
c) of reptiles.
d) amphibians.
e) of mammals.
