Скачать или смотреть The Blue Sea Dragon Glaucus Atlanticus...

Glaucus atlanticus common names include the blue sea dragon, sea swallow, blue angel, blue glaucus, dragon slug, blue dragon, blue sea slug and blue ocean slug

These sea slugs are pelagic; they float upside down by using the surface tension of the water to stay up, where they are carried along by the winds and ocean currents.

The blue side of their body faces upwards, blending in with the blue of the water. The silver/grey side of the sea slugs faces downwards, blending in with the sunlight reflecting on the ocean's surface when viewed facing upwards underwater.
Blue dragons feed on other pelagic creatures and other venomous creatures

This sea slug stores stinging nematocysts from the siphonophores within its own tissues as defence against predators. Humans handling the slug may receive a very painful and potentially dangerous sting.

This nudibranch is pelagic, and there is some evidence that it occurs throughout the world's oceans, in temperate and tropical waters. It has been recorded from the east and south coasts of South Africa, European waters, the east coast of Australia, and Mozambique.

The Blue dragons species geographical range increased northward by 150 km in the Gulf of California.
Since the middle of the 19th century, records of this species have been reported on the Azores.
Glaucus atlanticus was recently found in Peru in 2013, and in India in 2012. This is in line with the known habitat characteristics of the species: they live in warm temperate climates in the Southern pacific

Before finding Glaucus atlanticus off Andhra Pradesh, these nudibranchs were documented as having been seen in the Bay of Bengal and off the coast of India, over 677 kilometers apart.


Although these sea slugs live on the open ocean, they sometimes accidentally wash up onto the shore, and therefore they may be found on beaches.

At maturity The blue dragon can be up to 3 centimetres (1.2 in) in length,though larger specimens have been found. It can live up to a year under the right conditions.

It is silvery grey on its dorsal side and dark and pale blue ventrally. It has dark blue stripes on its head. It has a flat, tapering body and six appendages that branch out into rayed.

The Glaucus atlanticus is able to swallow the venomous nematocysts from siphonophores such as the Portuguese man o' war, and store them in the extremities of its finger-like cerata.

Picking up the animal can result in a painful sting, with symptoms similar to those caused by the Portuguese man o' war.

The symptoms that may appear after being stung are nausea, pain, vomiting,
