See bizarre-looking sea creature that eats stones and excretes sand caught on camera

A worm-like sea creature which eats stones and excretes sand has been studied in detail for the first time.

The Lithoredo abatanica was discovered in 2016, but scientist have now spent time finding out about how the organisms lives and functions.

It is a thick, white creature that can grow more than a metre long, and lives in fresh water, according to Science Magazine.

It was spotted on the island of Bohol in the Phillipines and researchers had their indepth work published by the Proceedings of the Royal Society B, today.

They discovered that the Lithoredo abatanica is actually a type of shipworm.

The slippery creatures have plagued sailors for centuries by chewing up the wood in ships.

The Wood-eating shipworms use their shells, which are covered in tiny invisible teeth, to drill into the wood.

The Lithoredo abatanica is a rock-eating shipworm which has less, but slightly thicker teeth, which it uses to scrape away at the rock.

Dr J. Reuben Shipwy said:

We had a few animals in a makeshift aquarium and you could basically watch them excreting fine particles of sand out of their siphon.

It is not known if the shipworms are extracting any nutrients from the stone or if the digestion process serves another purpose.
