The Lemon Shark

The lemon shark is a truly amazing and unique creature that lives in the ocean. Due to a light brown color the shark may merge with the sand bank, that's why this huge three-meter big fish has such name. Despite the big eyes, the lemon predator has poor eyesight, but due to the electropulse receptors the shark is an excellent hunter, which rarely misses a catch.

What is unusual about the lemon shark, and why it is so attractive for underwater depths researchers? This shark type is occasionally swims in fresh water. Primarily this is caused by the yellow predator ability to adapt to different salt concentrations. The lemon shark also has the ability to lie on the bottom and weep water through their gills, while other species of sharks has no possibility to rest, they constantly surf the ocean.

The lemon shark often can be found in shallow water, where it rests on the sand merging with the colour of bottom surface. The ability to vary the intensity of the color promotes perfect camouflage

Lemon shark, also known as Panamanian finetooth shark or brevipennate finetooth shark, is a large predatory fish, which inhabits coastal waters. The yellow hunter is found in the western Atlantic, including the U.S., Brazil, the Bahamas, the Caribbean, New Jersey. It is also found in North-East Atlantic and the coastal waters of West Africa.

The lemon shark commonly inhabits the eastern Pacific: Mexico, Southern California, and Ecuador. It is also found in the waters of the Caribbean Sea and the Gulf of Mexico.

Some researchers argue that this shark can inhabits the mouth of the rivers, adapting to the low, as well as an increased level of salt in the water. There are no proving documents, but many information sources often report the unique abilities of the lemon shark to inhabit fresh water rivers for a while. Obviously, the gatherings of small fishes, which inhabit rivers, attract the lemon predator. Who won't reject the treat?

Lemon shark habitats

The most common habits for the lemon shark permanent residence is continental and island coastal hills, bays at the mouths of rivers, and coral reefs. This specimen prefer rocky or sandy bottom. As a rule, the depth habitat of sharks is no more than 90 meters. It is the level there are the lemon shark main food supply, besides the water is much warmer than at depths.

The lemon shark has torpedo-like streamlined body, dorsal and ventral fins, which are distinctive features of Carcharhiniformes, the largest order of sharks. The main feature of the Panamanian finetooth sharks is yellow or light brown coloration. Due to this unique coloration the shark got its name. Notably that the lemon shark ventral side is significantly

lighter. The body of the shark hasn't any markings. The predator has a short broad snout, sharp teeth and huge eyes. The lemon shark lower teeth are narrow and triangular, they have styliform ends and are wide at the base. The upper teeth are also wide at the base and narrow at the top. Besides, the teeth are sloped inward the snout. The lemon shark is the owner of 3-5 rows of teeth, which are separated by furrows.

The dorsal fins are identical by its size. It should be noted that the dorsal fin top merges with the rear ends of the pectoral fins. The upper blade of the caudal fin is much larger than the lower one. In addition, it has a slightly concave trailing edge. The length of the largest specimen is more than three meters. Thus, in 1982, the lemon shark of 368 cm length and 250 pounds weight was fished. Researchers claim that the females are slightly larger than males. The lemon shark life expectancy is 30 years at an average.

The Panamian finetooth shark feed on sea fish, shellfish, squid, crustaceans. From time to time the yellow shark attacks a small sharks and rays. Sometimes it feeds on carrion. An adult shark daily dose is no more than five percent of its total mass. The yellow shark hunts at a depth of no more than one meter.

Notably, this type of sharks is omnivorous. The stomachs of yellow predators, as research shows, can be full of glass bottles, rubber tires, watches and many other entirely inedible items. Still, the lemon shark prefers bony fish and shellfish. Sometimes the predators attack small shark attack and seabirds.

Sharks mate in the spring and summer. This viviparous shark nurtures its brood for 10-12 months. Each shark gives birth to 8-12 pups of 60-70 centimeters long. Young sharks quickly adapt to their own existing and they are mother-independent. New born sharks feed on crustaceans, squid, clams, and small fish. The lemon shark puberty begins at 13-15 years old.

Lemon sharks stir sport fishermen's interest.  Fished huge creature, trapped by fishermen, are carved in the same way as other species of sharks used for food. As a rule, the lemon shark meat is up for sale, fins are for cafes and restaurants, and the skin is perfect for the haberdasher. Fish meal is produced of the shark waste. Sometimes the shark liver is removed and used in pharmaceuticals. The yellow predator fat is also of value.

A human should keep off this shark species. InternationalShark AttackFile statistics reports there were several lemon shark attacks on humans in Florida and the Caribbean. Several people were taken to hospital with severe injuries. Fortunately, there are no any lethal cases recorded. Waterways of human and Panamanian finetooth shark are often the same due to the predator inhabits coastal waters, which are popular among divers and surfers.

The lemon sharks temperament is really curious. This species has excellent memory and they are perfect trainees. In addition, the yellow predator is very vengeful and unforgiving. Notably, you may provoke these sharks to attack. They notice any sudden and abrupt movement and become ready to attack. The finetooth yellow shark is listed as a dangerous fish for humans.

Remarkably, the lemon shark is very sensitive to ship propellers noise. The point is that its rhythmic beats produce waves of certain frequencies, resembling the communication signals. Sometimes the panamanian predator follows ships in freshwater rivers.

The lemon shark has some enemies. Their main natural enemies are larger predatory sharks, and various skin parasites. A human can also be included in the number of the lemon shark enemies. However it also has friends, as the lootsman and remoras, their restless companions and commensals.

Today in the United States the lemon shark are kept in captivity for researches of new pharmaceutical drugs, drugs, and to study its sensory structures. The researchers managed to get the lemon shark brood in captivity. It is worthwhile to say that the yellow predator is subject to training.

What is remarkable is that species were able to learn to get food by pressing buttons on the bottom of the pool. After button clicking the bell rang and servants treated the big fish with meat. By the way, the lemon shark is more intellectual than other species of sharks.

Unfortunately, today the Panamanian finetooth shark falls under extinction. Most likely this is due to the constant hunt for this species. Meat, fins and skin of the lemon shark are of high value. Besides, the lemon shark needs new habitats due to mass deforestation of mangroves. It is no secret that shark kids hide in the mangroves escaping powerful adult predators. The extinction of the species is also caused by rather long reproduction.
