The glass squid is one of 7 strange but strangely beautiful creatures that live in deep ocean waters from about 200 – 1,500 m, where darkness almost covers everything. In the darkness of the ocean floor, the sparkling light of this squid attracts many explorers and divers when they accidentally encounter them.
The glass squid, scientifically known as Galiteuthis phyllura , is a rare species of squid. The glass squid’s eyes protrude from the side of its head and are controlled by muscles. No matter where the squid’s body is facing, the eyes will always focus in one place and create light below them.
Although they do not have powerful fang weapons like deep-sea fish, glass squid have their own abilities that help them survive on the ocean floor, which is their transparent body and luminescent ability. biology.
Two organs under the squid’s eyes, called photophores, emit light with an intensity small enough to illuminate below sea level around them. This light keeps squid safe on the ocean floor thanks to a light-reflecting trick that makes them completely invisible to predators at or below the squid, but very easy to see from other directions. Therefore, when it detects that the enemy is watching, the squid’s eyes emit bright light and disappear very quickly.
In 1984, a Russian fisherman named Novoulianovsk brought back a squid identified as a giant glass squid from a depth of 1,000 – 1,300 m in the Sea of Okhotsk. According to records, this squid’s body has 2 long tentacles with a length of about 115 cm, short tentacles with a length of about 40 cm, body length of about 265 – 275 cm, the total length of the squid is up to more than 4 cm. m.
