Carybdeida
Carybdeida is an order of cubozoan jellyfish, commonly known as box jellyfish. These jellyfish are characterized by their cube-shaped bell, which distinguishes them from other jellyfish groups. Carybdeida are found in tropical and subtropical waters worldwide, primarily in coastal areas with warm water. They are known for their potent venom, which can cause severe pain and even death in humans.
Characteristics
Carybdeida are characterized by the following features:
- Cube-shaped bell: This is the most distinctive feature of box jellyfish. The bell is typically square or rectangular in shape, giving them the appearance of a box.
- Four tentacles: Unlike other jellyfish, which have numerous tentacles, Carybdeida have only four tentacles. These tentacles are long and slender, and are lined with stinging cells called nematocysts.
- Well-developed eyes: Carybdeida have complex eyes that are located around the rim of the bell. These eyes are capable of detecting light and movement, and may help the jellyfish to navigate and hunt.
- Fast and agile swimmers: Carybdeida are among the fastest-swimming jellyfish, with some species capable of reaching speeds of up to 6.5 km/h.
- Strong venom: The nematocysts on the tentacles of Carybdeida contain a potent venom that can cause severe pain, muscle cramps, nausea, and even death in humans.
Environments
Carybdeida are found in tropical and subtropical waters worldwide, primarily in coastal areas with warm water. They are commonly found in estuaries, bays, and lagoons, but can also be found in open ocean waters. Some species are even found in freshwater habitats.
