Chirodropida is an order of box jellyfishes.

Alatinidae is a family of box jellyfish within class Cubozoa, containing the following genera and species:

Class Cubozoa: the box jellies.

Although the eyes probably do not form images, Cubozoa can clearly distinguish the direction from which light is coming as well as negotiate around solid-colored objects.

The medusa form predominates in the classes Scyphozoa (the common, colorful, large jellyfish) and Cubozoa.

The Cubozoa, the box jellies, contain some of the most dangerous jellyfish in the phylum Cnidaria.

Several free-swimming Cubozoa and Scyphozoa possess balance-sensing statocysts, and some have simple eyes.

Simple eyes are rather ubiquitous, and lens-bearing eyes have evolved at least seven times in vertebrates, cephalopods, annelids, crustaceans and cubozoa.

Chiropsalmus quadrumanus, commonly known as the four-handed box jellyfish, is a species of box jellyfish in class Cubozoa.

Clarifying the identity of the Japanese Habu-kurage, Chironex yamaguchii, sp nov (Cnidaria: Cubozoa: Chirodropida).

Staurozoa appears to be the earliest diverging; Cubozoa and the coronate Scyphozoa form a clade that is the sister group of Hydrozoa plus discomedusan Scyphozoa.

Most jellyfish stings are not deadly, but stings of some species of the class Cubozoa and the Box jellyfish, such as the famous and especially toxic Irukandji jellyfish, can be deadly.

Although conventionally considered to be an order in the class Scyphozoa, recent genetic studies suggest that Stauromedusae should be elevated to a taxon equivalent of Scyphozoa and Cubozoa, and should therefore be known as the class Staurozoa.
