A dolphin has been found washed up dead on a beach after apparently being killed by a pair of women's underwear that had wrapped around its flipper and ended up cutting through, almost to the bone.
An environmental monitoring team removed the Guiana dolphin carcass from the beach in the Brazilian municipality of Itapoa on Sunday May 16.
The veterinary team that autopsied the dead animal believes the underwear, which had seemingly been stuck on the animal for some time, contributed to its death.
The team believes the dolphin got its flipper tangled in the fabric when it was younger and that it would have compromised its ability to swim and to hunt fish.
The specimen was found to be a juvenile female with a length of around 1.4 metres and a weight of 32.2 kilograms.
The underwear was wrapped tightly around its flipper, embedded deep in its skin, close to the bone, as shown in a photos taken by wildlife authorities.
According to veterinarian Giulia Gaglianone, the dolphin's skin healed around the underwear, leaving it with a permanently open wound through which the material looped.
In addition to the injury caused by the underwear, the dolphin had signs of chronic weakness such as thinness, pneumonia and a large number of parasites in part of the ear and in the lungs.
It also had gill net marks around its face and breathing hole.
Natural fabrics such as cotton, linen and silk take months to decompose and synthetic fabrics such as polyester can take hundreds of years.
Scientists continue to warn that fabrics discarded in the sea pose a threat to marine wildlife.
The Guiana dolphin is found in the waters to the north and east of South America and in the waters to the east of Central America.
It is a near threatened species, mainly due to entanglement in nets.
