A bloody weird sea creature, described as a large condom, has been captured on video deep underwater off Northland.
The footage was caught by diver Ben Laurie, who was dwarfed by the ten-metre long pyrosome, an invertebrate marine specimen made of thousands of zooids, which are multicellular animals.
Laurie told Caters it was a once-in-a-lifetime moment off the coast of Cape Brett and he was vigilant to not venture too close - and we can't blame him.
But scientists say pyrosomes are mostly harmless filter feeders which only snack on plankton. Many have compared the serpent-like creatures, which can be up to 18 metres long, to a plastic bag, living wind sock and a large floating condom.
Pyrosomes have been called the unicorns of the sea by scientists due to the lack of knowledge about them. What we do know is that they move by sucking in water and blowing it out to push themselves with the current.
