Residents of Caleta Indígena found a species of Mako shark stranded. They assure that it is not common to see it on the coast, since it is from offshore and warm waters.

Neighbors of Tocopilla, in the Antofagasta region, found a species of mako shark stranded in Caleta Indígena.

The incident was captured on Tuesday morning, when a resident of the sector found the species of large size.

The president of the cove union, Franklin Vergara, told TocoLoa Noticias that this shark measured three meters and 13 centimeters, and weighed 243 kilos.

This type of species, Vergara explained, is not common to see it on the coast, since it is offshore and warm waters, ensuring that this shark had never been seen before in the cove sector.

This version is joined by John Concha, from the specialized shark laboratory of the University of Antofagasta, who considers that this is an oceanic species, that is, it is not seen on the coast and when it dies offshore it always goes to the bottom of the sea, or, if it floats, it is usually eaten by other marine animals.

Due to this, its presence on the shore is considered abnormal, so some parts of the shark were removed for studies.

They should cut it open and look for feathers or seal skin, A shark with bird flu will be quite the wake-up call.
 
There's a lot of blood coming out of the shark's mouth so I wonder if he washed up or was caught in the shallower waters? I found a science article about the same species acting like this off the coast of New Zealand. It could be behavioral change in response to food availibility changes.
