Carybdeidae
Carybdeidae is a family of cubozoans, commonly known as box jellyfish, that includes about 20 species. These are some of the most venomous animals in the world, and their stings can be fatal to humans. The family Carybdeidae is characterized by its cuboid-shaped bell, which gives them their common name. They also have four tentacles that extend from each corner of the bell. Unlike other jellyfish, Carybdeidae have well-developed eyes and a complex nervous system, allowing them to be active hunters and to navigate efficiently.
Common Names
Members of the Carybdeidae family are commonly known as box jellyfish. This is due to their distinctive cuboid-shaped bell, which gives them a box-like appearance. Some species are also known as sea wasps or killer jellyfish, reflecting their potent venom.
Characteristics
Carybdeidae have several key characteristics that distinguish them from other jellyfish:
- Cuboid bell: Their bell has a distinctive box-like shape, unlike the dome-shaped bells of other jellyfish.
- Four tentacles: Each corner of the bell has a single tentacle that extends from it.
- Well-developed eyes: Carybdeidae have 24 eyes, arranged in groups of six around the base of the bell. These eyes allow them to see and navigate their surroundings with precision.
- Complex nervous system: They possess a more complex nervous system compared to other jellyfish, which allows them to exhibit complex behaviors like active hunting and efficient navigation.
- Venomous nematocysts: Their tentacles are covered in stinging cells called nematocysts, which contain venom. These can deliver a powerful sting that can cause extreme pain and, in some cases, death.
Environments
Carybdeidae are found in tropical and subtropical waters around the world. They are typically found in shallow coastal waters, estuaries, and mangroves. Some species, like the Chironex fleckeri (sea wasp) are known to inhabit open ocean waters.
