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.

    They usually are found around the shore or river banks only walking onto the water for hunting. The only spider you will mostly find in a lake are diving bell spiders.

      https://en.wikipedia.org/wiki/Diving_bell_spider

      The diving bell spider or water spider (Argyroneta aquatica) is the only species of spider known to live almost entirely under water.

      That sounds neat.

      Their bite is often described as being very painful to humans and as causing localised inflammation, vomiting, and slight feverishness that disappears after 5-10 days.

      That sounds less agreeable than the giant raft spider.

        Sentence after that:

        However, solid evidence is lacking

        It’s really hard to get bitten by any spider. I can’t imagine how hard it must be to get bitten by spider that lives underwater. I have to check those wiki sources …

      Ah I misunderstood that a fen is actually a thing (non-native speaker here). So I correct my original post to “if you don’t live in a fen”

        As a native speaker, I’ve never heard the word “fen” in my life. So, that’s probably why they didn’t say that.

            Oh, I guess it was you who didn’t say fen. But it’s probably more correct to leave “fen” out, at least if you want to be understood. It is not s common word. I had to look it up.
