Why The Box Jellyfish is The Best Jellyfish

The Cubozoa, AKA The Box Jellyfish, is arguably the
coolest (and most venomous) animal in the world.


The medusa form of a box jellyfish has a squarish, box-like bell, from which its
name is derived. From each of the four lower corners of this hangs a short pedalium or stalk which
bears one or more long, slender, hollow tentacles. The rim of the bell is folded inwards to form a shelf
known as a velarium which restricts the bell's aperture and creates a powerful jet when the bell pulsates.
As a result, box jellyfish can move more rapidly than other jellyfish;
speeds of up to 6 metres (20ft) per minute have been recorded.





More reasons Box Jellies are cool(in my opinion):




One question remains,

Why would a box jellyfish need to sleep?


One possibility, suggested by Seymour and his colleagues, is that it uses its eyes to hunt.
"In the dark, when vision is limited, it makes a lot of sense to become inactive, decrease your energy used in locomotion
and divert it to growth."
