Keeping To An Underwater Theme,

there are four species,

 of blanket octopus that are so called because of the webbing between some of their arms, and they have a very specialised talent, the use tools, or I should say the arms of other creatures, they tear Portuguese man o'war tentacles off to use as weapons! as an aside if you see a Portuguese man o'war give it a wide berth, its tentacles which give a painful sting can be up to 165 feet long!

Joseph Elayani accompanied the Three P Diving Club on an outing underneath the waters off Romblon Island in the Philippines, and captured this remarkable footage of two colorful blanket octopuses, a longer video shows more amazing creatures seen on the same trip, one more wonder of the underwater world.
