a squid uses ink for selfdefance like when a shark or something bigger tries to eat the sqiud the squid burst out a lot of ink and no squid ink isn't used for pens
when the ink comes out, it lets the squid get away while the other fish is trying to see through the ink, which pretty much makes it 'blind' until the ink dissolves away.
they use it because when they spare ink they can swim away
Squid ink is made of Melanlin. But also has other chemicals in it that can attract other squids.
Octopus and Squids use there ink to fend off predators that may attack them and eat them. when a shark charges an octopus/squid will ink and confuse the shark so they can escape.
Squid use it for their defense mechanism.
to scare predators
Yep, they have an ink sac.

The squid's ink amount depends on the size of the squid. The ink is used to confuse and paralyze the squid's attacker so that the squid can escape.
you can only get it from a squid... sorry... you cannot make a squid ink...
ink is expelled from their ink sac
The squid's ink sac empties out into the esophagus.
The eye of the squid is not where its ink pouch is located. The ink pouch is located near the rectum.
Squid ink has a lot of protein and can heal tumors.
No as squid ink reacts with heat and cold and wouldn't be suitable for human skin
Colossal squids have an ink sac, so they have ink. However, not much is known about the ink.For further information, check out New Zealand's TePapa Museum site about the colossal squid: http://squid.tepapa.govt.nz/anatomy/article/colossal-squid-the-inside-storyQuote from the site: "All squid have a sac of ink inside the mantle. The ink is a dark liquid and is expelled through the funnel. If the squid meets a predator, it shoots out a cloud of ink, which hides the squid so it can escape. No one has ever seen a colossal squid producing ink so we can't be sure what the ink looks like or how the squid uses it. As there is no light down at 1,000 metres in the ocean, dark ink would be useless! It is possible that the colossal squid has luminescent ink."
