Shark Aquarium:D

Length - usually does not exceed 60-70 cm, but some individuals sometimes grow up to 1 m. Maximum weight - exceeds 2 kg. The caudal fin is long and low, its lower lobe is poorly developed. The dorsal fins are located in the rear half of the body, with the origin of the first dorsal fin located behind the base of the pelvic fin. The skin is rough, reminiscent of sandpaper. Males have larger teeth than females. Common catsharks are nocturnal. During the day, males rest on the bottom, while females hide in shallow water. They feed primarily on a variety of benthic (bottom-dwelling) invertebrates—crustaceans (crabs and shrimp), echinoderms, mollusks, polychaete worms, sipunculans, and tunicates. Their dietary preferences change with age: young sharks prey on small crustaceans, while adults consume more hermit crabs and mollusks.

A powerful body covered in thick skin with tiny, spiky scales. The skin on the belly is somewhat thinner, so when threatened, the fish tries to hide its vulnerable spot by turning its back to the enemy. The whale shark has a relatively small, somewhat flattened head with a wide mouth (about one and a half meters). The mouth is located in the center of the snout, which distinguishes it from other members of its family (whose mouths are located in the lower half of the snout). The eyes are small and deep-set. Even in large individuals, the diameter of the eyeball does not exceed 50 mm. They are located almost at the edges of the mouth. When threatened, the eyes retract deep into the sockets and are tightly closed by a fold of skin. The coloration is distinctive: the back and sides of the body are dark gray, mottled with yellowish or dirty-white longitudinal and transverse stripes. Between them are rounded markings of the same shade. The head and pectoral fins have similar spots, densely and randomly distributed. The belly is light gray. The skin of the fins and body has characteristic grooves and scratches that merge into a single pattern. The nature of the "pattern" is unique to each individual and does not change with age.

A solitary predator, but when hunting in the coast, sharks can form schools of two to five individuals. Hierarchy: females dominate males, large individuals dominate small ones. The ability to occasionally raise its head out of the water to get a better look at prey.

Powerful jaws with several rows of sharp teeth, capable of crushing even the most durable materials. A keen sense of smell allows them to detect the scent of blood from a distance of several kilometers. With the help of the lateral line, which runs along the sides of the body, sharks detect the slightest vibrations in the water, which helps them find prey and even hunt in the dark.

The hammerhead shark lives in warm and tropical ocean waters, preferring coastal areas and continental shelves. Migrations depend on the season and water temperature; during warmer months, sharks can travel long distances in search of food and more comfortable conditions. Adults are solitary or form small flocks. During their annual migration, they may gather in large numbers.

They found him in the ocean and decided, well, let's have a megalodon in the aquarium, we'll find a big pool. Silos is aggressive and dangerous for everyone, even those with a captain's mind, but sometimes he presses himself into a corner and gets sad when workers avoid him if they don't want to play and entertain him because of the danger that he might eat someone, but he is rarely affectionate and cannot smile because of the shape of his jaw like other sharks.

Peculiarities: An elongated body with a rounded, convex snout and large round eyes. The color is almost black, the fins have a noticeable light edging. The belly is luminescent. It reproduces ovoviviparously, with a litter of up to 8 young, each about 6 cm long.
