The young tortoises have scales on their legs to protect their face and neck when they suck themselves into their shells.

Does a tortoise have scales?

Scientists often refer to them as chelonians, because they are in the taxonomic order called Chelonia (from the Greek word for tortoise). They all have scales, lay eggs, and are ectothermic; they vary in size from fitting in your hand to about 1,800 pounds (817 kilograms).

Does flounder have scales?

Does skate fish have scales?

The skin of rays and skates is similar to that of sharks.

These scales point towards the tail and helps to reduce friction from surrounding water when the animal swims.

How strong is a pangolin armor?

The crossed lamellar arrangement of the keratin fibers in the pangolin scales enhances the fracture toughness.” The complex, hierarchical structure makes it hard for cracks to propagate after an impact, resulting in a Young’s modulus of ~1 GPa and a tensile strength of 60-100 MPa.

Is an axolotl cold blooded?

A salamander is a type of amphibian, a cold-blooded animal that has gills, can breathe air, and lives under water. We find axolotls mainly in Lake Xochimilco and Lake Chalco in Mexico. The species name is Ambystoma mexicanum.

What are the scales on a turtle shell called?

The shell is made up of large, hard scales called SCUTES. Most turtles have 13 scutes on the top shell.

What are turtle scales made of?

The turtle’s shell is covered in scutes that are made of keratin. The individual scutes as shown above have specific names and are generally consistent across the various species of turtles. Terrestrial tortoises do not shed their scutes. New scutes grow by the addition of keratin layers to the base of each scute.

What do you call a turtles legs?

Flippers. Limbs are flippers adapted for swimming. Sea turtles are awkward and vulnerable on land. Unlike land turtles, a sea turtle cannot retract its limbs under its shell. Forelimbs are long and paddle-like.

What is scaleless snake?

Scaleless Snakes Are Not Completely Scaleless They do have scales that completely line their bellies — called ventral scales — just like normal snakes. This is important because all snakes need ventral scales to effectively slither to travel — the scales grip the surface so the snake can pull itself forward.

What is a scaleless snake?

“Scaleless” is actually a misnomer for these snakes. They do have scales that completely line their bellies — called ventral scales — just like normal snakes. This is important because all snakes need ventral scales to effectively slither to travel — the scales grip the surface so the snake can pull itself forward.

What is the difference between fish and reptile scales?

Through reptiles and most of the fishes have scaley skin, they differ from each other. Reptiles skin is dry,rough and water-tight. Most of the fishes have a boney, scaley structure on their skin. But the species of fishes that do not have scales, like sharks, angel fish, etc have smooth and slippery skin.

What is the most armored animal?

The pangolin is also the only mammal with scales—similar to those of fish and reptiles, while the shell of the armadillo is bony in nature. These scales form an armour that covers the top of the head, all the back and tail, but not the face, throat, belly and the inside of the legs.

What turtles have claws?

Both sexes may use their claws to grip the seafloor as they crawl along underwater. Females may also use their claw as they move on beaches. So while sea turtles do use that claw on their front flipper, Dr. Innis also says that sea turtles also do just fine with no nails.

Which animals do not have scales?

Amphibians live part of their lives on land and part of their lives in the water. They have smooth, moist skin with no scales, feathers, or hair.

Are hedgehogs quills?

Most mammals have fur or hair that is somewhat flexible and soft. But the hair on the back of a hedgehog is a thick layer of spikes (or modified hairs) known as quills. These quills are made of keratin, the same stuff our hair and fingernails are made of.

Are hedgehogs related to elephants?

The lesser hedgehog tenrec does indeed look like a hedgehog, so much so that people used to think that the tenrec was a close cousin of the hedgehog. Scientists now think that the lesser hedgehog tenrec is really the cousin of elephants, aardvarks, and manatees and is not closely related to hedgehogs at all.
