The characteristics of the Whale Shark

Introduction

The Whale Shark is a fish belonging to the species Elasmobranchio oectolobiform. It is believed that they exist on the planet for approximately 60 million years. In 1828 this species was announced when a copy was found that measured a little more than 4 meters in length, captured by fishermen in South Africa and its holotype is located in the Natural History Museum of Paris. It was called a whale shark because it has the structure of a fish, but the size is similar to that of whales. 

Developing

Where the whale shark lives? The Whale Shark inhabits warm waters, can find in coastal areas of Honduras, Mexico, Venezuela, Panama, Tanzania, Taiwan, Western Australia or the Philippines, although some examples are usually the coasts of New York City (EE. UU.) characterized by being of low temperatures. They are located in the open sea about 700 meters deep by this is not common to compare with these sharks, although they can visualize from some coasts that have river mouths, coral atolls or affected lagoons. Whale shark characteristics measure more than 12 meters in length being the largest fish on Earth.

The head has a flattened and wide shape, on the sides are their eyes characterized by children and being very far from each other. The mouth is full of rows with small teeth and measures 1.5 meters wide. It has a pair of dorsal fins and another torque of pectoral fins, they move at a speed of 5 km / Hy the tail measures 2.5 meters. The skin has a thickness of 10 centimeters, the body is robust and elongated, the color of the back is dark gray, it is full of moles and lines with a yellowish tone while its belly is white. What do whale sharks feed on? His usual food is necton, kril, phytoplankton and necton.

However, they eat other types of fish such as mackerel, tuna, sardines and anchovies or crustaceans such as squid or crab larvae. In order to ingest your food, make a water filtration mechanism, absorb a lot to catch these living beings in their dermal denticles and avoid the passage of other fluids that it expels through a kind of ‘cough’. Locate the planning strategies or the fish previously affected with the help of its excellent olfactory, and you should only open your mouth as much as possible to drink the greatest amount of water. No need to advance quickly to achieve their prey. If there are large amounts of food, they form groups for food, but they mostly mobilize alone. Ballena sharks eat people? Affected feed on small sizes fish.

Reason why they are not a threat to the human being, their behavior around man is friendly and could also say affectionate. Despite having numerous teeth, they are tiny size and have no role at the time of feeding. Registered attacks are caused by self-defense in situations of danger such as hunting or capture of these animals. The damage caused are minor, since they cannot damage damage to their teeth but to give strong blows with their tail or torso. Ballena shark reproduction does not have an extensive knowledge of the whale shark reproduction process, because they are reserved at the time of mating. In 1996 it was announced that they are oviparous, that is, the mother has the eggs inside her body.

Until the embryo is fully developed and when it gives a light they are alive. The largest egg commission record is 300, although females are usually a little more than 20 eggs. Newborns measure 40 to 60 centimeters in length and during their first years of life are reduced in deep areas being difficult to study by man. Life expectancy of the whale sharks live up to 100 years or a little more, the first years are in the company of the mother to know how to feed quickly and quickly at the beginning of her own road in the open sea. It is known that they are sexually mature around 30 years of age, they reproduce until they reach the major stage, between 60-70 years and are dedicated to food. 

The whale shark is in danger of extinction The whale shark is considered "vulnerable to extinction" because it is one of the main objectives of the fishing industry in the areas where they are seen with reiteration such as Taiwan or Philippines, in both countries there is a law that prohibits their hunt due to the great killings they made, could end the life of more than 100 animals of this species every year. Since the beginning of the years 2000 a little more than 6 have been registered.000 copies, specifically reducing every 10 years. There are more reasons that risk their existence on the planet such as the degradation of corals and mangroves because of global warming.

conclusion

Ship traffic and plastic pollution. Ballena shark conservation There are currently several whale sharks in captivity in aquariums located in Japan and the United States with the intention of studying their behavior and preserving them alive to avoid their complete extinction. Other shares for conservation is the application of various laws in countries where they are frequently located and mobilized to avoid the import or export of their skin, meat or parts of their body. The most recognized are the CMS.
