The biggest jellyfish in the world

The marine environment is fundamentally different from ours. This world is fraught with many creatures that go beyond the usual ideas about things. Take, for example, jellyfish… This ancient form exists on the planet more than 600 million years, and some specimens have learned to grow to incredible sizes.

The biggest jellyfish in the world — hairy cyanea. Widespread in the Atlantic and Pacific oceans, but the largest specimens are caught in the Arctic. The reason for this is the lack of food in cold water, leading to late puberty and, consequently gigantism individuals.

This photo on the Internet met a lot. It definitely depicts cyanea, but the ratio of human and jellyfish here can be fixed with photoshop. The biggest jellyfish in the world was thrown on the shore of Massachusetts Bay in 1870. Its length was 36.5 meters, and the bell diameter is 2.3 meters.

In this regard, cyanea rightfully wears the title «the longest jellyfish in the world» and is considered the longest animal on the planet, as its main competitor — the blue whale reaches only 33 meters.

Other names or Arctic cyanea lion’s mane. This discomedusae (the 8-pointed shape), opaque. In Latin its name means «the hairy blue jellyfish», while in adulthood it is more colorful — it is dominated by brown, red and yellow tones. But the young cyanea is usually orange.

Normal specimens with a diameter of about 2 meters and a length of about 20 tentacles. The body of a jellyfish is an inverted bell with the blades. From its interior face tentacles, which the lanei very much — at each corner of the dome are in the range of up to 150 pieces, which are not drawn inside, and always ready to dig into a victim. In the centre is the mouth, which is the excretory opening. And move jellyfish jet method.

Cyanea lives in surface waters at depths up to 20 meters. It is a predator which uses its tentacles as lovchej networks, where the ends of stinging cells, the victim will have a strong poison. For small fish it is lethal to the larger animals leaves a lot of damage.

In humans, the largest jellyfish of the oceans can cause allergies, burns, but not death. The story «Lion’s mane» by sir Arthur Conan Doyle, where in contact with it killed two people, is fiction.

And besides, rare diver would swim in the Arctic without a wetsuit that protects from the cold. Interestingly, getting into more southern latitudes, cyanea will never grow more than half a meter. Upon meeting her in the warm waters without protection, a person need to wipe the clashes vinegar.

The life cycle of a jellyfish is quite unique. It consists of polypoides (attached to bottom) and actually medusozoa types.

The large jellyfish consist of female and male individuals. Males through the mouth spit Mature sperm into the sea, where they fall to the females in the mouth of the blade. In a few days the larva is transformed into a polyp, which is first fixed to rocks or plants. It will grow, eat and reproduce by budding (asexually). And in the spring the transformation is completed the larva of the Medusa, which is sent in the free swimming of a small eight-pointed star.

Jellyfish hunt groups — because they want to surround the plankton or a school of fish. Among this species of jellyfish is widespread cannibalism in the case of large jellyfish may swallow smaller relative. Natural enemies Tiana – turtles, birds and large fish never miss a tasty morsel of prey.
