A 36-feet long humpback whale has been found dead in the Amazon jungle, miles from its natural habitat.
Experts in Brazil have been left baffled as to how the ten-tonne animal came to be lying in the woodland area around 50ft (15 meters) from the sea.
The marine mammal was discovered last Friday in the middle of the undergrowth on the island of Marajo off the Araruna Beach, at the mouth of the Amazon River.
Scientists believe the creature died at sea and may have landed in the wooded area after rough seas and high tides threw it inland, far from the ocean.
A team from Semma went to the region to inspect the remains, believed to be a 12-month old calf, and to gather information which could help to explain how the aquatic creature crash landed in the jungle.
Video taken at the time shows the mammal splayed out in swampy mangrove surrounded by trees, with no visible signs of injury.

In a Facebook post by the NGO, Bicho D'agua Institute which is based on Marajo Island, biologists suspect that the calf become entangled in the mangroves after being thrown ashore by high waves.
The Maritime Herald suggested the animal may have been killed by swallowing marine plastics and the body was then washed inland.
Dirlene Silva, from the department of health, sanitation and environment (Semma) said to Brazilian media Journal O Liberal: 'We only found the whale because of the presence of scavenging birds of prey.
'The vultures were spotted circling above the carcass which was found hidden in the bush some distance from the sea.'
A team of ten biologists struggled to reach the body of the whale at the first attempt, and were only able to reach it at the second try, according Brazilian news site O Tempo Brasil.
Biologists from the Bicho D'agua Institute have been called in to collect forensic samples to determine the cause of death.
They believe the massive animal, which measures six feet wide, was already dead when it
