Reptiles are vertebrates that have scales on at least some part of their body, leathery or hard-shelled eggs, and share a number of other features. Snakes, lizards, turtles, crocodilians, and birds are animals. Like all vertebrates, reptiles have bony skeletons that support the skeleton of the head, neck, arms, legs and feet.
They also have cartilaginous skeletons, which are made up of cartilage and connective tissue. Snakes are the most common vertebrate in the world, but they are not the only ones. Amphibians and fish are also members of this group, as are insects and arachnids.

Does a alligator have a spine?
The caudal vertebrae of the American alligator number in the 60’s and can vary between specimens. As you go down the length, the usual pre- and post-zygapophysis, neural spines, and transverse processes begin to diminish. American alligators can be distinguished from the other species by the fact that they have a much larger head than the others.
This is due to the large size of their brain, which can reach up to 1.5 meters in length, making them the largest living crocodilians. They are also the only species of crocodilian to have two sets of teeth, the premolars and molars, as well as a second set of molar teeth on the lower jaw.
These teeth are used for grinding food into a fine powder that is then used to make a paste for the gizzard. In addition to their large head, they also have an elongated snout and a long, curved tail. Alligators are known for their ability to swim very fast, reaching speeds of over 30 miles per hour.
Do crocodiles have bony skeleton?
Despite their tough skin, they have a skeleton. The internal structures of their bones are what this means. The crocodiles are classified as a special type of animal with bones and muscles. Crocodiles have been around for millions of years, but they were not discovered until the 19th century.
The first crocodile fossils were found in South Africa in the 1820s. Most of these species are nocturnal, meaning they sleep during the day and are active at night. Crocodiles can live up to 30 years.
What does a crocodile have on its back?
The bony scales along the back are the “armour”, and some species are considered more heavily armoured than others. The scales protect the delicate inner organs from injury during fights with other crocodiles, and tooth marks in them can be used to identify a particular individual.
Crocodiles are carnivores, meaning that they eat meat, but they also eat other animals, such as birds, fish, amphibians and reptiles. They are also known to eat small mammals, including mice, rats, rabbits, guinea pigs and hamsters, as well as reptiles and birds. Crocodiles can live for up to 30 years, although they are not considered to be particularly long-lived.
Can alligators smell period blood?
It is recommended that all menstruating women wear a diaper in addition to a full wetsuit to help cover the scent of their menstruations. Like bears, gators can smell the menstruation, which will put your entire party at risk of being eaten by a gator. Gators are also known to be very territorial.
The best way to avoid this situation is to keep your distance from the animal as much as possible. Gators will not hesitate to attack you if they feel threatened, so be sure to stay as far away from them as you can.
Are alligators asexual?
American alligators are capable of reproducing sexually. The female alligator gives birth to a clutch of eggs after fertilization. The eggs hatch into tadpoles, which are then raised by the mother until they are able to fend for themselves in the wild. Alligators can live up to 20 years in captivity.
Which is bigger crocodile or alligator?
Crocodiles are the larger species and fully-grown will be up to a metre longer than even large alligators. They have long, v-shaped snouts and are a lighter colour. crocodiles have a toothy grin because of this v-shaped snout. crocodiles can’t close their snouts to protect themselves from the sun’s rays.
Instead, they open their mouths wide and expose their teeth. The crocodile is the largest of the crocodilian family, with a maximum body length of more than 1.5 metres (5 feet) and a weight of over 1,000 kilograms (2,500 pounds).
Do dead crocodiles float?
The crocodiles bones rained for a short time. A crocodile carcass can’t float forever. The crocodiles were floating in the water by the 24th day after sinking back to the bottom. “It was a very, very bad day for the crocs,” .
Do crocodiles have 4 eyes?
Not content with just one, the crocodile has a lower eyelid which in conjunction with the upper lid securely sandwiches a third eyelid which has the same shape and size as the second. The third eye is located on the lower lid just above the eye socket. In the reptile’s case, it’s located just below the eyeball. It’s a very interesting arrangement, but it doesn’t make much sense.
It would make more sense to have two eyes, one on each side of its head. That way it would be able to see in all directions, not just in front of it, and it wouldn’t have to rely on one eye for vision. But that’s not how it works in nature, so it must have been done in order to make it look more like a human.
