Anonymous users2024-02-13Seahorses can distinguish male and female from appearance, breeding mode, and body type.
1. The appearance is different
First of all, the male seahorse has a very prominent seed sac, which starts from the abdomen of the male seahorse and then extends to the tail of the male seahorse. But for female seahorses, there is no seed sac that the male seahorse has, and this is a very important difference between male and female seahorses.
2. Different ways of reproduction
The ventral surface of the tail of the male seahorse has a nursery sac, which is formed by the combination of skin strokes protruding from the left and right sides of the abdomen of the tail when the seahorse first reproduces, and it only leaves a small hole at the end. However, the female hippocampus's cavity will gradually expand with the expansion of the oviposition period, and some reproductive papillae will gradually form.
3. Differences in body shape
Male seahorses are generally larger and broader, while female seahorses are relatively smaller, much shorter than male seahorses, in addition, the mouth of male seahorses is pointed and tube-shaped, which cannot be completely closed, but the mouth of female seahorses is not pointed, and it is relatively easy to close.
Seahorse
The seahorse is a small marine animal with a length of 5-30 centimeters. It is named because the head is bent and the body is close to a right angle, the head is in the shape of a horse's head and forms an angle with the body, the snout is long and tube-shaped, the mouth is small, and the dorsal fin is one, all of which are composed of fin bars.

Anonymous users2024-02-12Seahorses should be divided into male and female.
The most obvious difference between males and females is that males have abdominal pouches, while females do not have abdominal pouches. Seahorses are the only animals on Earth that are born by males.
Male seahorses have brooding sacs on their abdomen, front, or sides. During mating, the female seahorse releases its eggs into the brood sac, and the male is responsible for fertilizing these eggs. Male seahorses keep their fertilized eggs in their brooding sacs until they are fully formed, when they are released into the seawater.

The habits of seahorses
Seahorses tend to live in places where there is a lot of algae, and because they are lazy, they usually use their curly tails to attach themselves to the stems and branches of seaweed to avoid being swept away by currents. When it is time to forage, it will temporarily leave the seaweed, but after swimming for a while, it will find a new place to reattach.
Seahorses mainly eat copepods, which are sensitive to fluctuations in water ripples and will quickly swim away if they spot an enemy approaching. Since the body structure of seahorses is not conducive to rapid swimming, they need to sneak close to their prey and then attack quickly, which has a success rate of more than 90%. Seahorses breed from May to August each year, and unlike all other animals, seahorses produce offspring in males.
