Jellyfish

Jellyfish are aquatic creatures characterized by their gelatinous, umbrella-shaped bodies and trailing tentacles. They belong to the phylum Cnidaria and are known for their simple structure and stinging cells called cnidocytes. Jellyfish use their tentacles to capture prey and propel themselves through water by pulsating their bell-shaped bodies. They have a life cycle involving medusa (adult) and polyp (larval) stages. Jellyfish are carnivorous, feeding on small fish and plankton, and some species are bioluminescent. While they play a role in marine ecosystems, large jellyfish blooms can have ecological impacts. Certain species can pose a threat to humans due to their venomous tentacles. Despite their potential dangers, jellyfish are subjects of scientific study and are fascinating for their unique characteristics.
