Close-up of the giant octopus fighting "double-handed" with a seal weighing about 120kg made the tourists on the coast in Kaikoura Bay, south of New Zealand not surprised.

The ocean survival battle took place in about 20 minutes before the octopus was torn into pieces by seals.

This impressive sea view is recorded by Video Conner Stapley, a witness and guide of this tour.

Conner said, this is the largest octopus he has ever seen. This life-and-death battle is very rare and even rarer at this time because normally, Conner only sees seals eaten in the afternoon.

Octopus was dubbed the ocean monster because it possessed long, rough tentacles but was still imprisoned in pain by seals.

Seals often eat small fish, squid, crustaceans, seabirds and octopus. But octopus is the hardest prey because its bite contains a painful toxin.
