A pair of rare ‘kick-boxing’ shrimps have been discovered off Dorset. The mantis shrimps, usually found in tropical waters, are reputed to be able to deliver punches with the force of a small calibre bullet, writes Jo Mooring-Aldridge.

Two of the three-inch long shrimps were found in trawler nets in Weymouth Bay. Bathers have been advised to approach them with caution and not try to handle them.

Marine biologists believe that these are probably from the Mediterranean, and could be anywhere along the South Coast.
