Biggest Jellyfish Species Introduction Jellyfish are also known as Jellies and are aquatic animals that swim freely with a soft gelatin umbrella-shaped body and sweeping tentacles. The tentacles can be used to capture prey or also for protection by emitting a painful sting. The bell part of the body can vibrate which helps the jellies in movement though they depend on ocean currents to move long distances. Jellyfish are classified under kingdom Animalia, phylum Cnidaria, subphylum medusozoa. The subphylum is further classified into three groups of jellyfish; Scyphozoa which are true jellyfish, Cubozoa are box jellyfish and Staurozoa which are stalked jellyfish. Jellyfish are present on Ocean surfaces and the deep sea. True jellyfish can only be found in salty water though there are some species of jellyfish present in fresh water like the Craspedacusta sowerbii species. Jellyfish are not considered true fish as they are invertebrates. As long as they feed, fully grown jellyfish spawn every day. The lifespan of jellies differs with species, some live for a few hours and some for a few years. The Turritopsis dorhnii species is said to be immortal as it can transform from medusa to polyp stage in some circumstances. Jellyfish are carnivorous and they feed on small fish, other jellyfish, fish eggs, and planktons. The jellyfish are growing in numbers due to overfishing of fish that prey on them.

Do Cnidarians replace their stinging cells once used? Many people are familiar with the Jellyfish sting.

example, increases its inter-pedalia distance (IPD) by 3 mm (0.12 in) per day, reaching an IPD of 50 mm (2 in) when 45 to 50 days old. The maximum age of any individual examined was 88 days by which time it had grown to an IPD of 155 mm (6 in). Behavior The box jellyfish actively hunts its prey (small fish), rather than drifting as do true jellyfish. They are capable of achieving speeds of up to 1.5 to 2 metres per second or about 4 knots (7.4 km/h; 4.6 mph). A fully grown box jellyfish can…
