Up to 3,750 female fen raft spiders believed to be at 12 sites across the UK now

The UK’s largest breed of spiders, which can grow to the size of rats and hunts fish, are making a comeback in Britain.

From near-extinction in 2010 - when only a handful remained as their wetland homes were destroyed by humans - the number of fen raft spiders are now steadily increasing thanks to recent conservation efforts.

The spiders are set to have their best year on record at nature reserves ran by RSBP.

The conservation charity revealed that the most recent survey estimates the total number of female spiders to be up to 3,750 across 12 sites in Norfolk and Suffolk Broads alone.

The spider can spin a web as large as 25cm and can grow to the size of a man’s hand.

    I hope it wasn’t to try to escape fishing spiders because the US has 9 from the same genus. And Dolomedes tenebrosus is even larger than our European ones.
