The body of an enormous female Leatherback Turtle was brought to Melbourne Museum on Thursday last week after washing up at Airey’s Inlet.

A member of the public spotted the ailing turtle while it was still alive. Local authorities called the Melbourne Aquarium, which runs the Turtle Rescue and Release Program that rehabilitates tropical turtles that have strayed into cold southern waters. Unfortunately the Leatherback Turtle was too unwell to save and it lived just a few more hours. It was brought to Melbourne Museum early on Thursday morning for post-mortem examination to work out why it died.

Melbourne Aquarium vet, Dr Rob Jones, says it’s only the second Leatherback Turtle to wash up in Victoria since 1999, with smaller species such as Green Sea Turtles and Loggerhead Turtles more commonly assisted by the successful Turtle Release and Rescue Program.

Dr Jones examined the turtle on Thursday afternoon. “The age is difficult to guess,” he explains. “She had an inactive ovary, so she was possibly still immature or had laid eggs within the last six months. But at two metres long, the size suggests she was mature.” He found a small ulcer in her intestine that was probably from parasite, and signs of dehydration, but no clear cause of death. “It was disappointing not to be able to find the answer.”

The skeleton of the turtle will become part of the Museum Victoria research collection, since complete skeletons of this species are rare. The museum will also retain soft tissues for the DNA collection and barnacles and mussels from its shell for the Marine Invertebrates collection.

The Leatherback Turtle (Dermochelys coriacea) is the largest living turtle and has the widest distribution of the sea turtles. Their soft shells are unique; other species have tough protective plates called scutes as a kind of external armour, but Leatherback Turtles have small bones embedded in tough leathery skin. Another distinctive feature of these animals is their diet – they eat mostly jellyfish and have evolved a mouth full of fleshy spines to grip their soft prey. They migrate long distances in search of food, often visiting southern waters near Victoria between January and May when the sea is warm.

Leatherback Turtles are critically endangered and have suffered serious declines due to human activity. They are often drowned in fishing nets or choke when they mistake plastic bags for food.

My son was on school camp down at Angelsea when authorities came to collect this beautiful creature. He couldn't believe it's size. I hope it is put on display for everyone to marvel.

Wonder if they tested its blood for nuclear contamination from the Japanese tsunami etc. As a wildlife rescue/rehab volunteer its so very sad to see another beautiful animal affected this way with no autopsy cause - would love to know the blood work though
