While meeting with the Marine Turtle Patrol Team for routine data collection, they informed us that they had found two dead turtles on the beach. We would normally go to investigate and try to determine the cause of death which is commonly from poaching or being caught in fishing nets! On arrival at the location of the first dead turtle, we discovered it to be an Olive ridley sea turtle (
Lepidochelys olivacea) which likely died from being caught in a fishing net as the body was intact with no obvious injuries. While walking down the beach to location of the second dead turtle, the patrollers started telling me that the carapace of this one was different to what they have seen before. I thought it may be from a juvenile Leather back (
Dermochelys coriacea) as we normally work with Olive ridleys. Once we arrived at the second carcass, I saw two sets of claws sticking up and immediately knew this was not a sea turtle! But what was it and how did it get here? On closer examination of the shell and skull, it was clear it was a Soft shell terrapin which I had never found in Angola before and much bigger than any Soft shell I had ever seen before!

The location where this fresh water terrapin washed up was on the Atlantic side of a peninsula in the mouth of the Congo River. We believe this terrapin died somewhere up river and was washed down the Congo and into the ocean were it eventually washed up on the Atlantic shore of the peninsula.

That's one heavy creature! I would guess at +- 60kg

The boney part of the the carapace measured a CCL of 55cm and CCW of 54cm. The total length of the soft shell was CCL: 106cm

I could'nt resist taking the skull, what a stench!

The cleaned up skull. There were huge jaw muscles conected to the jaw and skull!

What a shame one can only guess how old this creature would have been

For those of you who are still wondering what species, I believe this to be an African Soft Shell Terrapin (
Trionyx triunguis) but I'm still waiting for confirmation on that so if anyone knows better please speak up.
An inaccurate naturalist is a pest and a danger, forever perpetuating illogical deductions and landing later naturalists in trouble. Damm and blast them all to hell in the most painful way. C.J.P. Ionides
