Turtles do have the ability to breathe underwater.
A turtles ability to "breathe" underwater is because of how their metabolism is affected by their body temperature.
Turtles however do need to come up from the water to get some more oxygen as they cannot breathe underwater for very long.
Although turtles can hold their breath for 45 minutes to one hour during routine activity, they normally dive for 4-5 minutes and surfaces to breathe for a few seconds in between dives.
Turtles can hear as they have the ability to hear although turtles can't hear as good underwater.
A humans outer ear is shaped to help draw sounds in toward the outer ear, but turtles have no outer ear.
The skin flaps of turtles ears allow vibrations and low-frequency sounds in the ear canal -- so the turtles can hear to some extent, but their hearing isn't sensitive.
Turtles don't have night vision although turtles can see somewhat in the dark.
Tortoises however do have night vision, and are able to see in the dark when they need to.
This is due to the extreme amounts of rod cells they have in their retinas in comparison to humans as well as most other animals.
Most people would be surprised to learn that tortoises are able to see in the dark.
It is safe to touch turtles although some turtles such as snapping turtles can bite and you should wear thick gloves when touching those types of turtles.
Turtles are safe to touch although they can sometimes bite and so it's best to wear some gloves when touching a turtle.
But if it's a pet turtle and they've been around you and trust you then they are pretty safe to touch even without gloves.
Turtles are not poisonous although some turtles can and will bite you and can cause some major damage.
But turtles are usually safe to touch.
There are no poisonous turtles, and there are no known venomous turtles.
However, there have been reported cases of mortality of having consumed meat from the hawksbill turtles.
Because of this, people from the island test hawksbill turtle meat for poison by throwing the liver of the turtle to the crows.
Turtles live on average of 10 to 20 years.
However some species of Turtles can live as long as 50 to 80 years and even up to 150 years.
However most turtles live between 10 to 20 years as pets and some live about the same lifespan in the wild as well.
Some Turtle Species are legal in India as pets although some Turtle Species are Illegal in India.
However the trading or sale of Turtles is illegal in India.
The trade of turtles and tortoises is illegal in India.
Placed under schedule – I of the Wild Life (Protection) Act, 1972, turtles and tortoises have the highest level of legal protection in the country.
Some species of tortoise and turtles are not legal to own in India.
The Indian Star Tortoise and the Red Ear Slider are among a few types of reptiles that are unsuitable for rearing in an apartment space, and illegal to own.
A turtle and a Tortoise are almost the same.
However the Tortoise is a different type of turtle.
Tortoises are turtles, but not all turtles are tortoises.
Turtle shells are more streamlined to aid in swimming.
One major key difference is that tortoises spend most of their time on land and turtles are adapted for life spent in water.
Tortoises have club-like forelegs and 'elephantine' hind legs.
Turtles can live on land for a short while unless they are equipped to fully live on land.
A Tortoise is a type of turtle that can live on land.
Tortoises (family Testudinidae) live exclusively on land and have anatomic features distinguishing them from other turtles, but the term tortoise has long been used to refer to other terrestrial testudines as well, such as the box turtle and the wood turtle.
Turtles can be aquatic, semi-aquatic, or mostly terrestrial.
Tortoises are turtles that live on land and aren't equipped for water.
Turtles drink water.
Sea Turtles will drink the sea water they are swimming in.
If you have a turtle in an aquarium the turtle will pee and poop in the water they drink and swim in so the water will need changed often.
All sea turtles drink only seawater all of their lives.
They have special glands behind each eye, called "salt glands" that they use to get rid of all the salt from the seawater.
Turtles do bite but they bite with their beak as the turtle has no teeth.
Turtles do not have any teeth and instead turtles have a beak like a bird does.
Some turtle bites can cause a lot of blood loss or can be at vulnerable parts of the body.
These bites can have serious implications when not treated as quickly as possible by professional medical personnel.
The wound bleeds profusely – If you are bleeding excessively, then you need to call 911.
Using their strong jaw muscles and hard beaks, carnivorous turtles crush the shells of their prey – crabs, sea urchins and clams, for example.
Baby turtles have something called an egg-tooth, or caruncle, but it's not really a tooth.
Turtles can and do see in color as turtles have excellent color vision.
Turtles are also particularly sensitive to shades of red and can differentiate between different shades of red better than humans do.
Not only can turtles see color, but research also suggests that it's likely that turtles can see a broader spectrum of colors than humans.
A turtle is a dinosaur as turtles are a reptile which are also related to the dinosaurs.
DNA hypothesis suggests that turtles were a sister group to the archosaurs (the group that contains the dinosaurs and their relatives, including crocodiles and their ancestors and modern birds and their ancestors).
A second hypothesis posits that turtles were more closely related to lizards and tuataras.
The earliest marine turtles are believed to have appeared during the Jurassic period, but it wasn't until the Cretaceous period 100 million years ago that sea turtles began to evolve.
Prehistoric turtles coexisted with dinosaurs until they went extinct 65 million years ago.
Turtles are an order of reptiles known as Testudines, characterized by a shell developed mainly from their ribs.
Modern turtles are divided into two major groups, the side-necked turtles and hidden neck turtles which differ in the way the head retracts.
Although their brains have become more complex, turtles are not capable of performing the same tricks and tasks and mammals and other species.
However, this does not mean they are not intelligent.
Their main concern is survival, so turtles learn how to survive, how to get food, and how to stay safe.
Most turtle species live from 10 to 80 years.
But sea turtles and large land tortoises can live to be much older.
Their lifespan can be 150 years or more.
As with whales, sharks, and other species, it is often difficult to determine a turtle's exact age.
