Scyphozoa (jellyfish)

Scyphozoa, commonly known as jellyfish, are marine animals characterized by their soft, gelatinous, umbrella-shaped bodies called bells, which can pulse rhythmically to move through the water. They have long, trailing tentacles equipped with stinging cells used to capture prey like small fish and plankton. Jellyfish lack a backbone and have a simple nerve net instead of a brain. They are found in oceans worldwide, from surface waters to deep seas, and play a crucial role in marine ecosystems. Despite their delicate appearance, some species can deliver painful stings to humans, so caution is advised when encountered in the water.
