The sizes of a leopard shark vary from 1.2 to 1.5 meters in length. She is a species of Kunya shark. The body is long and graceful with a short, rounded muzzle. Prefers living in silty or sandy places with a flat bottom, as well as near algae, rocky reefs or open coastal zones. It is harmless and non-aggressive to humans, so a photo of a leopard shark can be taken without fear of being bitten.
Pearls of the shark world
There are several potential threats that we must pay attention to so that the leopard shark population remains stable. The most important problem is recreational fishing. These are popular sharks for fishing because of their close proximity to the coast, unique coloring and tasty meat. In California, more leopard sharks are hunted than anywhere else, and in 1992, the California Department of Fish and Wildlife established prey restrictions that have since allowed populations to recover.
Surprisingly, small leopard sharks are also the target of another unique fishing trade for aquariums. They can fit in large aquariums, and become popular pets simply because they easily survive in an aquarium environment (easier than other species). They are unique, beautiful, they are very easy to catch.
Habitat
If you live on the west coast of North America - somewhere between Washington and Mexico - there is a good chance that tens or hundreds of leopard sharks are swimming somewhere near you right now. Leopard sharks prefer shallower waters than their brothers in the open ocean. They like to travel through the thickets of kelp, they even come and go with the tide, looking for tasty pieces. Small leopard sharks can be found in the waters only 30 cm deep, so don't be surprised if you meet them while walking along the coast.
Leopard sharks often form flocks with individuals of their own species and even with other species of sharks of the same size. They usually remain in place in the region in which they were born, although from time to time they cross a distance of several hundred miles. In general, their stay in one place makes it easier for biologists to study and track these sharks.
Main features
One of the distinguishing features of this species are distinct bands located on the dorsal surface. Extra dark spots are along the sides. In adults, the pectoral fins have a wide triangular shape. The anterior margin of the first dorsal fin appears behind the posterior margin of the pectoral fins. The caudal fin is elongated. It is generally devoid of a lower lobe.
This species is an active, strong, fast swimming shark, often performing wave-like movements. It is known that they form large flocks, sometimes combining with gray or brown marten sharks (Mustelus californicus and M. henlei) and katrans (Squalus acanthias). Shark diet consists of shellfish, shrimp, crab, octopus and fish. Large sharks, such as the great white one, prey on leopards.
Breeding and offspring
Sharks usually breed slowly. Leopard sharks are no exception. It takes 10 to 15 years for the female to reach puberty. They spend up to half their lives just preparing for breeding. However, after they appear from 7 to 36 cubs per year. It is known that sharks specially spend time in warm waters, which help accelerate the development of babies in the womb.
Females of leopard sharks give birth to fully formed babies in the shallow water known as nurseries, safe from predators. Leaving newborns here, they are sent back to breed and breed the next generation.
Interesting Facts
Leopard sharks are one of the cutest and most beautiful representatives of predatory fish.
Here are some interesting facts about this view:
- Sometimes a tiger leopard shark is called Galeocerdo cuvier - a member of the gray shark family. However, this is a completely different shark, and do not confuse them.
- This species of sharks is viviparous. Female eggs develop and hatch inside her. Newborns have a length of about 8 inches (20 centimeters).
- Newborn sharks grow very slowly and reach maturity in only ten years.
- Leopard sharks are more active at night than during the day. Sometimes they can be seen motionless lying at the bottom.
- The maximum life expectancy of this species is estimated at 30 years. In captivity, they live up to 20 years.
Scientists say hundreds of leopard sharks were found dead in San Francisco Bay, and dozens at Foster City. This massive mortality could be caused by meningitis due to fungal bloom in stagnant water.
