It’s purple, it’s slimy, it lives off the Norfolk coast - and it’s got international marine scientists very excited.

No, not the creature from the black lagoon but the sponge Hymedesmia - now officially declared as a brand new species of sea creature.

The sponge was found off Sheringham on a 20-mile underwater chalk reef which is the longest in Europe and is now regarded as a fragile eco-system of international importance.

The discovery came during a Wildlife Trusts’ survey of the entire East Coast, from Essex to Northumberland, carried out during National Marine Week in August.

Altogether 352 species of marine wildlife were found including 126 seaweeds, several of them previously unrecorded.

The sponge, which feeds on small particles in the water, has been identified by expert Dr Claire Goodwin of the National Museums of Northern Ireland who said that because the reef is unusually made of chalk there could be other “new” sponge species living there.

A TV documentary telling how Hymedesmia was discovered will be shown tonight, Monday, on BBC1 at 7.30pm.


  • Do not fall for it EDP. yes it might be a new species but all these media feeds could end up in Cromer fishermen being banned from fishing over the reef where they have fished for centuries. The scientists and diving groups and wildlife organisations behind this "discovery" ( I thought Percy Trett wrote about it years ago) would like a " no take" order to supposedly protect something that seems to have been doing ok up til now.

  • It is not a new species. It has been there all the time. It was a undiscovered species which has now been discovered and is a new species to science, that is if it is a newly discovered species.

  • Here we go again,it may be a new species to scientists but i have been pulling it up on my pots and anchors for years as have all the other fisherman.Its a shame this wonderful reef that has never been harmed in all the years it has been fished is now in danger from the thieving hands of divers who love to take pieces home for the mantlepiece
