The Franciscan endangered dolphin got killed last week after the tourists reportedly pulled it out of water to take pictures.
People, who were at the beach spotted the baby dolphin and puled it out of water and held it like trophies ignoring the discomfort shown by the animals.
After seeing the pictures posted on facebook by the beach-goers, the Argentina Wildlife Foundation issued warning to the public to avoid disturbing marine animals and to stop such incidents to happen in future.
A spokesperson wrote on website, 'The Franciscan, like other species, cannot remain for much time out of the water. It has thick fatty skin which provides warmth, so the hot weather will cause rapid dehydration and death.'
'At least one of the animals [from the photos taken in Santa Teresita] died. The incident prompts us to inform the public about the urgent need to return these dolphins to the sea if one is found on the shore. It is vital to help rescue these animals, because every Franciscan counts.'
As per the reports of The Argentina Wildlife Foundation, the Franciscan dolphin is one of the rarest and smallest dolphin in the world. It is 'vulnerable to extinction' as only 30,000 dolphins are believed to be left on the planet.
