Haliclystidae

The Haliclystidae are a family of cubozoan jellyfish that are known for their distinctive box-shaped bells. They are commonly called box jellyfish, sea wasps, or cube jellies. Haliclystidae are a diverse group, with about 50 species described, and are found in tropical and subtropical waters around the world. CharacteristicsHaliclystidae are characterized by their cube-shaped bells, which give them their common name. Their bells are typically small, ranging in size from a few centimeters to a few inches. The bell is often transparent, with a smooth or slightly wrinkled surface. Haliclystidae also have four tentacles, which are typically long and thin, and are located at each corner of the bell. The tentacles are covered in stinging cells, called nematocysts, that are used to paralyze prey. EnvironmentHaliclystidae are found in a variety of marine environments, including coastal waters, estuaries, and the open ocean. They are often found in warm waters, but some species are known to tolerate colder temperatures. Some species, such as the box jellyfish (Chironex fleckeri), are found in shallow waters, while others, such as the sea wasp (Carybdea xaymacana), are found in deeper waters.Common NamesHaliclystidae are commonly known as box jellyfish, sea wasps, or cube jellies. These names reflect the distinctive shape of their bells, which are box-like, rather than the rounded or umbrella-shaped bells of other jellyfish.ReferencesWorld Register of Marine SpeciesA comprehensive phylogeny of cubozoans (Cnidaria: Cubozoa) based on morphological and molecular data
