Jewel squid or squid Histioteuthis is a species of cock-eyed-squid as the state of their eyes is dissimilar. This species of squid are found swimming above the mid-Atlantic ridge. They can swim at depths of 1640-6561 ft (500-2,000 m). These jewel squids are also called bioluminescent photophores since the jewels covering the body are bioluminescent photophores. This species of squid form shallow marine sediments. However, their bioluminescent body makes it easy for big predators to find them at great ocean depths. This species has a semi-upright-like posture which helps them look upside down and also sideways when moving in the ocean.This squid is also called a strawberry squid because of its strawberry-like colored cells called photophores. These dot the skin of squid and provide distinctive light. This squid has asymmetrical eyes which helps them to perceive light in both light or dim surroundings. The squid spy on its prey by the large, tubular yellowish eye angle which is facing towards the surface. Squids are unique sea creatures which are also consumed by humans as a great seafood delicacy across the world. This can add to their decrease in population, along with waters becoming polluted, which makes it difficult for them to survive.For more relatable content, check out these Humboldt squid facts and flying squid facts for kids.

It is known by that a squid which is living deep exhibit reduced growth rates.How do they reproduce?The male squid performs various displays with the help of bioluminescence to attract the female squid.

In these animals, the mismatched eyes benefit them as the small size eye searches for food or prey and the bigger eye sees beneath the squid if there are any predators. They roam above the surface of the mid-Atlantic ridge.How cute are they?Jewel squids of the genus Histioteuthis are unique in their looks and have a cute appearance mainly because of their eye structure, size, and color. They are found mostly in the ocean and above the surface of the mid-Atlantic ridge. They are ocean predators hunting for prey at deep depths in the water of the ocean.
