This weird and wonderful creature resembles a rocket, but it is actually a deep sea creature from the Arctic. More specifically, it is a type of jellyfish. The 'swimming end' of the jellyfish is roughly around 3.9 inches in length.
However, the colony length can exceed 6 feet! It has been observed at depths of around 660 and 2620 feet, with the most it has been recorded at being 6600 feet.
It is very hard to see as the depths in which they live mean that next to nothing in terms of natural light reaches them. Because of this, not much in the way of studies have been done on them.
It is thought that their diet may consist of krill, decapods, and other crustaceans. They catch them in their colony spreading their tentacles to ensnare their prey.
