Whether a seahorse is a horsefish or not, what exactly is it?

Ichthyidae, sea lombera, a general term for the genus Hippocampus. The seahorse is named because its head resembles a horse's head, but it is interesting to note that it is a peculiar and precious small fish in the shallow sea sea of the order Sea Dragon, belonging to the family Hydrosauridae, the head is flattened, the head has 2 nostrils on each side of the head, the head is at right angles to the trunk, the chest and abdomen are protruding, composed of 10 12 bone rings, the tail is slender, with four edges, often curled, the whole body is completely wrapped by membranous bone sheets, with a spinless dorsal fin, no pelvic fin and caudal fin. The male hippocampus has a nursery sac on the ventral surface, in which the eggs are laid for hatching, and can reproduce for 2-3 generations a year.

Captive breeding of seahorses has been successful. Seahorse is a kind of precious traditional Chinese medicine with high economic value, which has medicinal functions such as strengthening the body, tonifying the kidney and strengthening yang, relaxing tendons and activating the nerves, reducing inflammation and relieving pain, calming the nerves, relieving cough and asthma, especially for diseases of the nervous system. In addition to being mainly used to make various synthetic drugs, seahorses can also be directly taken to strengthen the body and treat diseases.

Gasterosteiformes, a general term for several small fish species in the warm sea. The body is encased in an armor formed by a ring of bones, the tail is bent forward and can be curled, the head is in the shape of a horse's head and forms a horn with the body, the snout is long and tube-shaped, and the mouth is small. One dorsal fin, all composed of fin bars.

The eyes can move independently. They are of various sizes and are about 4 30 cm (in) long. Poor swimmer, generally living in coastal zones, among seaweed or other aquatic plants, with their tails wrapped around them.

Swim upright and rise or sink by propelling each fin and changing the air content in the swim bladder. Feeds on small creatures that are quickly inhaled by mouth. The male carries the fertilized eggs, which the female lays in the nursery sac at the tail of the male until hatching.

When the juveniles hatch, the male twists his body and releases the larvae through the only opening in the brooding sac. Seahorses are rare aquarium ornamental animals. Species include small seahorses (hippocampus zosterae) native to the Atlantic, which are smaller than other species; Brown seahorse (H. Brown) in Europe

Ramulosus or H guttulatus)；Pacific-born seahorse (h.) kuda)；Australia's medium-sized white seahorse (h

Class, Sea Dragons, a general term for the genus Hippocampus. Seahorses get their name because their heads resemble the heads of horses.

If you can be a horse to ride 94 horses.

Seahorses belong to the category of fish.

Seahorse is a collective name for several small fish species of warm sea fish in the family Hydrosauridae of the order Thornfish, and is a small marine animal that belongs to the class Bony Fishes taxonomically. It breathes through gills, has vertebrae, dorsal, pectoral and caudal fins, and is 5 30 cm long.

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. The eyes can move independently. Seahorses are slow to move, but they are highly effective at catching fast-moving, hiding-minded copepods in the Atlantic, Europe, Pacific, and Australia.

Seahorses are fish.

Seahorses belong to the class Bony Fishes and are marine fishes, but they are small in size and have an upright body, which is not very similar to other fish, and seahorses eat only live food, not dead animals.

The seahorse is also a general term for the small fish of the family Sea Dragon, although its appearance is different from the fish we are familiar with, it also relies on the fins on the sides of the body to move, and it is also an animal that breathes by the gills. However, due to their size, they cannot move very fast, and their mobility is easily affected by the flow of seawater, so their tails can curl and wrap around the branches of seaweed, so they generally live in areas where seaweed is abundant.

Morphological characteristics of the hippocampus

The hippocampus has a flattened head, with 2 nostrils on each side of the head, the head is curved at nearly right angles to the body, and the body of the fish is thick and flattened, completely enclosed in the bony ring; The mouth is a pointed tube-shaped, and the mouth cannot be opened and closed, so it can only suck small animals in the water as food, and the eyes can be turned up and down, left and right, or back and forth, respectively; The thorax and abdomen are protruding, and the trunk is composed of 10 12 bony rings, generally about 15 30 cm long; The tail is slender and quadrangular, and the tail end is slender and pointed, which can be curled and held, and is often curled.

The head is curved, at a large obtuse or right angle to the trunk, with a prominent crown at the top and small spines at the end; snout tubular, mouth small, terminal, gill hole small; The whole body is completely wrapped by membranous bone sheets, with a spinless dorsal fin, no pelvic fin and no caudal fin. dorsal fin located between trunk and tail; The anal fin is short, the pectoral fin is well developed, and there is no caudal fin, and its fin is not easy to see with the naked eye.

However, with high-speed photography and careful observation, you can see the moving spines. These spines can move back and forth seventy times in a second. Depending on the wave that travels from the end of the dorsal fin to the other end, the seahorse can ride the wave and move freely back and forth or up and down.

Male fish have a nursery sac on the ventral side of the tail, and the eggs are laid in it for hatching, and can reproduce 2 to 3 generations a year.

No, the seahorse is neither a mammal nor an amphibian, but a fish.

Mammals are a relatively high animal, they generally reproduce in a viviparous manner, and have mammary glands to nurse their offspring. Amphibians, on the other hand, are developed from fish, which can live on land or in water. Seahorses are neither viviparous, unable to suckle, nor can they live on land, so they are neither mammals nor amphibians.

Named for the curved head and the near-right angle of the body, the seahorse is slow to move, but it is very effective at catching fast-moving, hi-hiding copepods in the Atlantic, Europe, Pacific, and Australia.

Habits

Due to its mimic adaptation characteristics, seahorses also have special habits, and prefer to inhabit subtidal sea areas where algae or sea leeks are abundant. It is often attached to the stems and branches of seaweed with its curly tail, and sometimes hangs upside down on floating seaweed or other objects, drifting with the current.

Seahorses are generally active during the day (morning and afternoon) and are stationary at night. Seahorses often make gurgling noises due to pharyngeal muscle contraction when water quality deteriorates, oxygen is insufficient, or when they are attacked by predators, which signals farmers to "call for help", but they also make sounds when feeding on bait on the water surface, which should be distinguished.
