Mire Squid

Mire Squids are giant cephalopod Kaiju that appeared in Kong: Skull Island.

Appearance
Mire Squids resemble colossal red squids with eight long arms.

Personality
Mire Squids are ambush predators that lurk in the waters of Skull Island for unsuspecting prey.

Origins
The Mire Squid is a giant cephalopod that exhibits a hybrid of squid/octopus physiology. Initial hypotheses suggest this lake-dwelling creature is a distant cousin of the Giant Pacific octopus, though with some notable evolutionary mutations. Again we see evidence of the superthermal gigantism unique to this environment, though a much more detailed geothermal study will be required if we are to understand the environmental factors which have led to the growth of such enormous lifeforms. Like other octopoda, the creature exhibits deimatic behavior when threatened, expelling a thick cloud of black ink that is heated within the furnace-like temperatures of its mantal chambers. In this way, the Mire Squid conceals itself from attacking predators while boiling them alive.

Its beak-like jaws, usually hidden within the rubbery flesh of its huge, bulbous head, are mounted within a complex muscle bed that enables them to rotate like fan blades. Hunting beneath the surface, the creature will swirl these jaws into a centrifuge, stirring up a vortex-like whirlpool that sucks prey down into its gaping maw.

Kong: Skull Island
While Kong was examining himself after the battle with the Sky Devils, he took notice of a Mire Squid waiting to ambush him before he dragged it out from the water. After a brief fight, Kong killed the Mire Squid by crushing its head with his foot. He proceeded to eat it before carrying away the rest of the carcass to be eaten later.

Agility
Mire Squids are shown to have highly flexible arms, which is shown when one tried to restrain Kong.

Aquatic lifestyle
Mire Squids are able to stay underwater indefinitely.

Endurance and Stamina
The Mire Squids' endurance might be high since one is shown taking multiple hits from Kong, even after some of its arms got pulled off. They may have high stamina in order to exhaust their prey from struggling.

Hunting
Mire Squids are shown to be solitary hunters. They hunt by waiting until their prey have come close enough.

Ink cloud
Mire Squids can expel a thick cloud of heated black ink from their mantal chambers to defend themself when threatened.

Physical abilities
The Mire Squids' multiple arms are strong enough to restrain massive vertebrates such as Kong.

Stealth
The Mire Squid can stealthily move through the water to avoid being spotted from most prey and predators.

Whirlpool
Mire Squids can rotates their jaw like fan blades to create a whirlpool in the surrounding water in order to pull in and swallow their prey.

Trivia

 * Kong's battle with the Mire Squid may have been a reference to his brief fight with the Giant Octopus in King Kong vs. Godzilla.
 * Kong devouring the slain Mire Squid is a rare instance of a kaiju eating another: while Godzilla was stated to be a "predator" of the M.U.T.O. he does not consume their remains after they are killed.
 * In the official novelization, another Mire Squid attacks and tries to eat Slivko before it has one of its arms cut off by San Lin and is finished off with a flare to its ink sac, killing it.
