How does a vampire squid protect itself?

Answer 1

The vampire squid is actually somewhat dangerous (relative to it's size, I'm not sure how big it is), only meaning it can hold it's own in a fight. However, like any squid it can produce ink, yet that probably wouldn't be much help in the pitch black. So it also has luminescent patches on it's body and tentacles to distract predators from it's vulnerable parts (eyes, base, ect...). I'm not sure if this is the defensive ability, but it can also turn it's body completely inside-out.

Answer 2

they put their tentacles over their heads and under the tentacles there is spikes so when it puts its tentacles over its head it make a spiky shield.

Answer 3

They turn themselves inside out.
