The String Jelly or Apolemia uvaria is a colony of animals called a siphonophore and is made up of many individuals. It is sometimes said to be the longest invertebrate in existence but I think it could share this accolade with the Lion's Mane Jellyfish which also appears off the UK each year (see separate item). Often seen broken into small sections with each section viable in its own right, this String Jelly measured approximately 20m although larger individuals have been recorded. There are mixed reports of it carrying a sting - apparently it affects some individuals quite badly and others not at all.
