JELLYFISH Meaning and
Definition
-
A jellyfish is a marine invertebrate belonging to the phylum Cnidaria and class Scyphozoa or Hydrozoa. Characterized by a gelatinous umbrella-shaped bell, typically transparent or translucent, and a trailing tentacled structure with venomous stinging cells known as nematocysts, jellyfish are among the oldest and most primitive forms of life on Earth.
The body of a jellyfish consists of a soft, gelatinous substance called mesoglea, which provides buoyancy and support. They lack a true brain or central nervous system but possess a basic nerve net that allows them to sense their surroundings and react to stimuli. The tentacles, positioned around the edge of the bell, serve both as a locomotive and predatory apparatus. Utilizing venomous nematocysts, they immobilize prey and bring it towards the oral opening located at the center of the bell where digestion takes place.
Jellyfish exhibit a wide range of sizes, shapes, and colors, depending on the species. They can be found in all the world's oceans, from the surface to the deepest depths, and are known to be highly adaptable and resilient. While many species are harmless to humans, the stinging cells can cause painful skin irritations or more severe reactions in some individuals.
Jellyfish play a crucial role in marine ecosystems as both predators and prey. They contribute to nutrient cycling by consuming plankton and small fish and being consumed by larger creatures. However, certain environmental conditions, such as pollution or overfishing, can lead to jellyfish population explosions, resulting in negative impacts on marine biodiversity and human activities such as fisheries and tourism.
