As the saying goes, "the millennium king eighty thousand years old turtle", the turtle has always been the longest-lived animal in people's cognition. In recent years, although people's aesthetics are strange, more and more people like turtles, some people think that turtles are cute and cute, some people think that turtles are cool, I don't know if you like turtles or not?

The alligator turtle is very large, an adult alligator turtle, the shell can be 80 cm long, the weight can reach a terrifying 200 pounds. Alligator tortoises like to inhabit lakes, usually catch some fish as food, alligator tortoises although a carnivorous animal, but not very picky eaters, as long as they catch themselves, they can be used as food.
The alligator turtle is most famous for their mouth, their mouth has not lost the bite force of the crocodile, a bite down, not to mention the hand, even the bone can bite off, so if you have the opportunity to see the alligator turtle, please do not use your fingers to tease. Let's talk about another species of turtle.

The turtle, called the "hawksbill turtle", is a very large sea turtle, their body length can reach up to 1.1 meters, and the weight is even heavier than the crocodile turtle, up to 230 pounds. In addition, hawksbill turtles are also one of the few turtles with toxins, because hawksbill turtles prefer to eat stingrays.
Most of the spiny animals carry toxicity, which leads to the toxicity of the meat of the tortoiseshell, and it is this toxicity that makes the tortoiseshell have few natural enemies in the water. However, the development of the coastline by humans has seriously affected the tortoiseshells that need to nest on the shore, making it difficult for the tortoiseshell tortoiseshell to reproduce.

By now, hawksbill turtles have become a critically endangered organism, and humans are trying to save it.
Tortoises
Speaking of large-sized tortoises, we have to talk about tortoises, the tortoise family is the giant of the tortoises, such as the Aldabra tortoise we are going to introduce, it is one of the largest tortoises in the world, we look at them from the outside, they are like moving islands.

Their body length is at least 1.2 meters or more, and their weight is more than twice that of the tortoiseshell we introduced above, and the heaviest can even reach 500 pounds, but the huge size also causes the Aldabra tortoise to move very slowly, except for extremely high defense, almost no attack power.
Fortunately, the Island of Aldabra Atoll, where they live, is a protected island, where all the Aldabra tortoises live, they do not have any predators on the island, they can sleep when they are tired, and eat when they are hungry. Because of this, the population of Aldabra tortoises has reached more than 100,000.
Moreover, in this living environment, some Aldabra tortoises even live longer than 200 years. The tortoise to be introduced next is much larger than the Aldabra tortoise. Their name is galapagos tortoise, and it is also a type of tortoise named after the island where they live.

This tortoise is the largest tortoise known to man, its size is very exaggerated, their length is at least more than 1.2 meters, but their weight is much larger than the Aldabra tortoise, can reach a terrifying 700 or more, even if you only look at the data, you can imagine the huge size of this turtle.
However, having a huge size comes at a price, and the price of galapagos tortoises is extremely slow movement, their speed is 260 meters per hour, sometimes below this value, they usually need seven or eight hours to find food, and they may not even be able to find it.
However, even if they can't find it, it doesn't matter, they can easily do not eat for 6 months, as long as they can find food during this period, it will not affect their survival.
Red sea turtles, green sea turtles and leatherback turtles
The Galapagos tortoise is already the limit of tortoise size, but it is not the limit of all turtles, and it is the turtle that exceeds this limit. For example, regulars in the animal world, green sea turtles and red sea turtles.
Green sea turtles can reach up to 1.5 meters in length and weigh at least 600 pounds, this turtle is very physical, they were not green when they were young, because they were carnivores when they were children, but when they grew up, they became herbivores, often feeding on seaweed and kelp.

It is precisely because they often eat these green plants that their appearance gradually begins to show green, so they are called green sea turtles. The red sea turtle is larger than the green sea turtle, they are about two meters long, and the weight can reach 1,000 pounds, also because the red sea turtle has more flesh.
As a result, people go to the areas where they live to fish heavily, especially in Mexico, where they like to eat turtle meat, and the number of red sea turtles that have been killed by humans is also decreasing dramatically, and has been listed as an endangered species. Next up is the king of all the turtles, the leatherback turtle.

Leatherback turtle is arguably the largest turtle in the world, how big is it? Their body length is up to 3 meters, and their weight is directly up to the tonnage level, and the maximum weight can reach more than 1 ton. However, there is a reason why leatherback turtles can grow so large, because they usually feed on jellyfish.
The weight of the food eaten in a day can even reach 70% of its own weight, which belongs to the big stomach king of the turtle. However, such a large body did not bring any convenience to the leatherback turtle, but brought them danger. According to common sense, the average predator does not touch the turtle.

However, the shell of the leatherback turtle is not hard, it is a relatively soft material, and the leatherback turtle has no means of attack, so they become a delicacy in the shark's mouth.
