Do alligators have mitochondria?
The complete mitochondrial genome of the alligator, Alligator mississippiensis, was sequenced. The size of the molecule is 16,642 nucleotides. Previously reported rearrangements of tRNAs in crocodile mitochondrial genomes were confirmed and, relative to mammals, no other deviations of gene order were observed.
What are the functions of an alligator?
Alligators play an important role in maintaining ecosystem balance. Sitting at the top of the food chain, alligators are apex predators and help keep other animal populations in balance. By digging holes and leaving trails throughout marshes, they create habitats for fish and marine invertebrates.
What is the function structure of a crocodile?
Crocodiles have powerful jaws with many conical teeth and short legs with clawed webbed toes. They share a unique body form that allows the eyes, ears, and nostrils to be above the water surface while most of the animal is hidden below. The tail is long and massive, and the skin is thick and plated.
Why do crocodiles turn white?
When a crocodile lightened, the same melanosomes would contract into tight packets, leaving more surface area without pigment to absorb light. This expansion and contraction is all that’s needed to achieve the relatively quick but reversible color change seen across multiple species’ skin.
What are alligators adaptations?
Physical Adaptations: Powerful tail used for swimming. Eyes and nostrils on the top of their head so they can remain submerged while breathing and keeping an eye out. A “third eyelid” called the nictitating membrane sweeps sideways across the eye to protect the eye during feeding and diving.
Is alligator an amphibian?
Crocodiles are very similar to amphibians but hey are not termed under amphibians. In fact they are a part of the reptile family.

What is the adaptation of a crocodile?
Crocodilians can move about on land – with surprising speed, particularly when alarmed or angry – but their bodies are mainly adapted for a life in water. The nostrils, eyes and ears lie along the top of the head so that the animal can hear, see, smell and breathe when the rest of the body is submerged.
How did alligators adapt to the swamp?
Their back feet are webbed, meaning there is skin between their toes. This skin can help push the water while they are swimming, allowing them to move quickly through swampy waters. Alligators have long snouts and strong tails. These physical characteristics can help them dig burrows, which are tunnels underground.
Do alligators live in saltwater?
There are many things you may encounter when swimming in the ocean. Alligators probably aren’t one of them. While alligators can tolerate salt water for a few hours or even days, they are primarily freshwater animals, living in swampy areas, rivers, streams, lakes, and ponds.
What is the main function of mitochondria?
The main function of mitochondria is to produce energy for the cell. Cells use a special molecule for energy called ATP. ATP stands for adenosine triphosphate. The ATP for the cell is made within the mitochondria. You can think of the mitochondria as the energy factory or power plant of the cell.
What is the reproductive cycle of a alligator?
Alligator sinensis has a similar reproductive pattern, but because it is a smaller species, it matures somewhat earlier. Mating occurs from May to June and nesting begins in July. Alligator sinensis produces smaller clutches (average, 24 eggs).
How many mitochondria are in an animal cell?
Some simple cells contain only one or two mitochondria. However, complex animal cells that need a lot of energy, like muscle cells, can have thousands of mitochondria. Energy Factory The main function of mitochondria is to produce energy for the cell.
What is the Alligator sinensis nature reserve?
In order to protect the endangered animal an Alligator sinensis Nature Reserve was established by the Government of Anhui Province in 1982. The Reserve (30’6’31”-6’N and 180°-119° 6’E) covers five counties of Nanling, Jingxian, Shuancheng, Lanhxi, Guangde of Anhui Province.
