Crocodiles are a kind of dioecious animals, which can distinguish male and female. Crocodile breeding is done by male and female crocodiles, they will mate in the water, and then the mother crocodile will come to the shore to lay eggs and be responsible for hatching eggs, but also raise young crocodiles. Although they can distinguish between male and female crocodiles, when they are relatively young, they can not distinguish between male and female crocodiles, and generally look the same until they are 2 years old. When they grow up, the sex characteristics will be more obvious and then they can be distinguished.
In fact, when the crocodile eggs hatch, the sex of the baby crocodile is related to the surrounding temperature. When the temperature is around 31 degrees, the male crocodile hatches. When the temperature is lower than this, the hatched crocodile is usually a mother crocodile.
1. The number of tail bones: When crocodiles are large enough, they can be distinguished by the number of tail bones. Female crocodiles have fewer tail bones, generally one less than male crocodiles. This is because they have ovaries, which take up part of the larger position, and the bone will be missing a section. Male crocodiles have more bones in their tails near the anus than female crocodiles.
2. Size: If the crocodiles to be compared are all the same age, they can be compared by their size. Generally speaking, if they are the same age, the male crocodile will be larger than the female crocodile.
3. Breeding season: If it is the breeding season of crocodiles, then it depends on the behavior of the male and female crocodiles. Female crocodiles, after mating, will be on land, before laying eggs, will dig holes in the ground in order to lay eggs in the hole, this behavior is the female crocodile.
