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."
They go to the surface of the water and breathe the air.
No, they have to surface to breathe. They can go a long time between breaths though.
because its hard to breathe thin air above earths surface, the higher you go its hard to breathe oxygen.
Yes; jellyfishes breath through all the surface of their body. Jellyfish cannot breathe air but they breathe water.
Dolphins can't breathe underwater because they are mammals. They go to the surface to breathe and then hold their breath while underwater
go ask your mom, shes a a squid
Most fish are too small to eat squid. Sharks can go for squid.
It is simple, it uses breathing tubes and go tothe surface of the water to get air and closes the tube when it go in the water.

dolphins can breathe underwater for about 15 minutes after that they have to go back to the surface to breathe some oxygen ps: dolphins are mammals
A shark is not a mammal because they use gills to get the oxygen out of the water so they can breathe. The shark doesn't NEED to go above the water's surface. Whales use their blowholes to breathe. So they must go to the surface, otherwise, they will drown.Hope this helped! :)
