It confuses and wards off their predators.
These squids also light up their whole body for matching the background they live in to save themselves from their potential threats.
They have three visual pigments or light-sensitive cells and double layered retina, which allow them to differentiate between bioluminescence and ambient light and to decipher the color pattern produced by other members of the squid family.

They suck in water through a tube and then expel it, propelling them through the seas and allowing them to escape from dangerous predators like sharks, dolphins, sea turtles, seals and even humans, who hunt squid for their commercially sold meat.]]> 2019-03-17 05:40:37 UTC https://padlet.com/Qiwen/mafgm939cbha/wish/342078400 ctp2399j https://padlet.com/Qiwen/mafgm939cbha/wish/342078691 Like their octopus cousins, squid produce ink and keep it in an ink sac near their rectum. When threatened, squid can expel this ink in the face of a predator, confusing it and allowing it to escape. This ink expulsion is commonly combined with its quick getaway abilities]]> 2019-03-17 05:47:34 UTC https://padlet.com/Qiwen/mafgm939cbha/wish/342078691 ctp2399j https://padlet.com/Qiwen/mafgm939cbha/wish/342079103 Squids have among the largest eye size to body size ratio in the entire animal kingdom. In fact, the eyes of Architeuthus dux, the giant squid, can get to be as large as a dinner plate. Squids use these large eyes to bring in as much light as possible at night, when they often hunt, and to see in the depths of the deep seas where no sunlight reaches.]]> 2019-03-17 05:57:27 UTC https://padlet.com/Qiwen/mafgm939cbha/wish/342079103 ctp2399j https://padlet.com/Qiwen/mafgm939cbha/wish/342079150 Squids have 10 tentacles protruding from the base of their elongated torpedo-bodies. All of these arms are lined with suction cups, usually with small hooks embedded in their centers. Two of the squid's arms are over four times the length of the other arms and are used to catch fish and other prey; they shoot out like grappling hooks and grab a prey item, then quickly reel it in back toward their mouths.]]> 2019-03-17 05:58:20 UTC https://padlet.com/Qiwen/mafgm939cbha/wish/342079150 ctp2399j https://padlet.com/Qiwen/mafgm939cbha/wish/342079254 Squids have powerful beaks, like parrot beaks, centered at the base of their heads in between their tentacles. These beaks are extremely powerful and are used not only to chew food but to crush crab and mollusk shells, making them easier to swallow.]]> 2019-03-17 06:01:06 UTC https://padlet.com/Qiwen/mafgm939cbha/wish/342079254 Qiwen https://padlet.com/Qiwen/mafgm939cbha/wish/342221423 2019-03-18 02:26:58 UTC https://padlet.com/Qiwen/mafgm939cbha/wish/342221423 Qiwen https://padlet.com/Qiwen/mafgm939cbha/wish/342221673 firefly squids on the shore]]> 2019-03-18 02:28:39 UTC https://padlet.com/Qiwen/mafgm939cbha/wish/342221673 Qiwen https://padlet.com/Qiwen/mafgm939cbha/wish/342222323 2019-03-18 02:32:08 UTC https://padlet.com/Qiwen/mafgm939cbha/wish/342222323 Qiwen https://padlet.com/Qiwen/mafgm939cbha/wish/342223603 Bobtail squid have bioluminescent bacteria within their bodies. These glowing bacteria are then used as camouflage by the bobtail squid to mimic the moonlight at night and to eliminate their own shadows, thereby protecting against predators.
What might be even more impressive is that the bobtail squid can actually control the brightness of the glow caused by the bioluminescent bacteria within them. They have special light organs inside of their mantles that act as filters for the light, allowing them to adjust their glow to match the moonlight.
