Tragic: A lone dolphin washed up on the beach. Photo via infobae.com

In just under a week, 23 dolphins have washed up on the coast of Buenos Aires Province. The news is a tragic blow for conservationists and animal lovers alike, seeing how the dolphins concerned belong to the La Plata (also know as Franciscana) species, whose status is considered “vulnerable” by the International Union for the Conservation of Nature.

It’s been a turbulent few weeks for the species, to say the least, with a bunch of idiots murdering one for the sake of a few selfies in Santa Teresita last month.

The cause of death of the 23 dolphins remains unknown, but natural causes and human involvement have not been ruled out. Many of the dolphins were found with marks on their skin from contact with fishing nets, a biologist told press.

The dolphins were found on the beaches of San Clemente del Tuyú, Mar de Ajó, La Lucina, Aguad Verdes, Las Toninas and Santa Teresita.

There are important colonies of the dolphins off Argentina and Brazil’s Atlantic coast, where the dolphins come to breed between spring and summer. Humans have been catching the dolphins, especially off the Uruguayan coast, in fishing nets, killing large swathes of the population for decades.
