World's longest recorded sea creature

'World's longest recorded sea creature' among new finds

Several new species have already been discovered during the project, Institute spokesperson Carlie Wiener said, as well as the "world's longest recorded sea creature" - a 45-metre long siphonophore found at Ningaloo canyon, off Western Australia.

A siphonophore is a type of colonial organism; it's a string-like arrangement of many individual animals - zooids - that live connected together in a colony, and carry out different functions that allow the collective to digest food, float, reproduce and move about.
