The seahorse, also known as Hippocampus, is one of the most fascinating aquatic animals. Although its name may seem harmless and amusing, this small and delicate creature hides a series of interesting characteristics and behaviors. The seahorse belongs to the Syngnathidae family, which also includes pipefish. It is a unique and amazing representative of the animal kingdom.Seahorses live in temperate and tropical waters worldwide, from coral reefs to coastal areas and estuaries. Although they are called seahorses because they resemble dogs, these creatures have nothing in common with mammals. They are fish, more precisely bony fish, with a skeleton made up of bones.
A remarkable aspect of the seahorse is its distinctive shape and unique way of moving. These creatures have an elongated body and five pairs of wings or branchiostegal fins instead of regular fins. These wings are located on the dorsal side of the seahorse and are used for movement in the water. Additionally, seahorses stand out because they can independently move each of their wings detached from their main body.
The seahorse has a long and prehensile tail, which allows it to cling to marine vegetation or other underwater structures. This ability is used to protect itself from the marine current and to hide during hunting. Furthermore, the long tail allows them to adopt various positions and move easily through dense vegetation.
Another amazing characteristic of the seahorse is its reproductive system. During mating, the female transfers the eggs to a special pouch located in the male's abdomen. There, the female and male exchange genetic material, after which the male takes responsibility for incubating the eggs. The incubation period can last between 10 and 28 days, depending on the species. When the eggs hatch, the male releases the larvae into the water, where they fend for themselves.
Seahorses have a varied diet, mainly consisting of small crustaceans and zooplankton. They feed on their prey using their famous proboscis, which resembles a short trunk. Through this proboscis, seahorses can suck in their prey and quickly bring it into their mouths.
Although they are harmless animals, seahorses face a series of threats. Water pollution and the destruction of natural habitats are some of the biggest dangers to their survival. Therefore, it is crucial to take measures to protect these vulnerable creatures. Many countries have conservation programs aimed at preserving habitats and raising awareness among people about the importance of protecting seahorses.
In conclusion, the seahorse is an amazing and remarkable animal with unique characteristics that differentiate it from other aquatic species. Its distinctive shape, unique movement, and fascinating reproductive system make it a subject of study and admiration. Protecting these delicate and vulnerable animals is essential for maintaining the ecological balance of aquatic ecosystems.

Facts
Origin
The sea dog (Squalus acanthias) is a small but very aggressive shark, also known as the spurfish. It lives in the cold waters of the Pacific and Atlantic Oceans, in the northern hemisphere. It prefers to sit on the bottom of coastal waters with low temperatures, around 15 M and at depths of 10-200 m.
In English it is called Piked dogfish.
The name of the spur fish comes from the fact that the dorsal fin has spines, which can cause very painful wounds.
Feeding the Sea Dog
Being a very greedy predatory fish, its food is very diverse, consisting of fish (mackerel, anchovies, herring, hake, horse mackerel, capelin, cod, gobies), Crustaceans (crabs, shrimp) and Mollusks (sea snails, calamari).
Features Sea Dog
As we have already said, dorsal fins have spines, which can cause very painful wounds. The ventral fins are large and much elongated, the anal one is small, and the cod fin has asymmetrical lobes, with the upper one larger than the lower one.
Viewed as a whole, the body of the sea dog is fusiform, reaches 1 m in length and can weigh about 9 kg. In exceptional cases the length of some specimens reaches 1.6 m. the male is always smaller than the female.
Its coloration is gray-brown with white spots on the dorsal side, respectively light gray with bright spots on the ventral side.
In this species the eyes are very large, oval in shape, and the color of the iris can vary greatly. The gill slits appear positioned on the sides, the snout is sharp and flattened, and the jaws are provided with small and very sharp teeth.
The shark is the fear of fish in almost all seas and oceans. The Shape of its head is so well adapted for attack that it easily disembarks water in pursuit of prey, moving like a real torpedo.
Shark fishing: the Sea Dog is a very skittish fish and moves away immediately at the approach of a speedboat.
It is rarely caught on a train, with deep gulls. It can be caught on land, from the anchored boat or from the shore in quiet areas with great depths near the shore. Favorite bait is blue mackerel or small octopuses.
Breeding Sea Dog
The mating season takes place in the winter months, and reproduction is ovoviviparous.
The female gives birth to 2-11 live cubs after a gestation of almost 2 years, which are at first 22-33 cm long and resemble adults very well.
