The Ragworm is highly common around the UK. It lives in a burrow in muddy seabeds and looks a lot like an underwater millipede. They are the opposite of picky eaters and will feed on just about anything. They spin a mucus net at the entrance to their burrow in which they catch plankton and other small particles. If it's slim pickings, they leave the burrow in search of bigger food - scavenging on whatever is available or hunting out small invertebrates. Ragworms are a favourite food of flatfish and wading birds, including Curlew and Bar-Tailed Godwits.

Found around all UK coasts, particularly common in estuaries.
Ragworms were given their scientific name "diversicolor" as the males change colour during the breeding season, going from a dull brown to bright green.
