Crocosaurus

Crocosaurus is a giant 46 meter (150 foot) ancient crocodile from the Congo that was awakened by an illegal diamond mining operation. After a brief rampage, the Crocosaurus was captured by English hunter Nigel Putnam and loaded onto a cargo ship along with its eggs to be brought to the United States for research.

During the transit, the ship was attacked by the Mega Shark, who survived its battle with the Giant Octopus years earlier, freeing the Crocosaurus. After a brief fight, during which Mega Shark eats some of Corosaurus' eggs, both animals are forced to retreat. While rampaging through the United States, Crocosaurus continues to lay eggs on the coast, which later hatched. Together with her hatchlings, Crocosaurus was lured to an underwater volcano near Hawaii. Using explosives, the US Navy manages to kill both beasts and the hatchlings.

Battle vs. Giant Octopus (by KevlarNinja)
On a island of the cost of Florida, the Crocosaurus is guarding her eggs. Suddenly, she notices something splash on the water. It's the arm of a giant octopus! The Crocosaurus swims toward it, seeing it as a threat to her eggs. She swims to the patch of water where she saw the arm. But then, the octopus strikes, wrapping it's arms around her! The Octopus trys to bite her on the neck with it's beak, but her scaly armor stops it.

The Crocosaurus slips out of the octopus's grip. She then turns around and bites an arm, useing a deathroll to help rip it off. The disembodied arm twists and tries to get the Crocosaurus, but ends up sinking to the deep ocean. The Crocosaurus claws at the Octopus, but does little damage. The Octopus wraps it's remaing arms around it's attacker. The Crocosaurus snaps off another arm before getting out of the Octopus's grip. The Crocosaurus swims around and bites the Octopus on the back of the head, and carries the Octopus to shore. The Octopus grows weaker and weaker. The Crocosaurus reaches shore and drags her prey onto shore. Unable to breath, the Octopus dies.

Successful, the Crocosaurus roars. She starts to hear chirping. It's her young. She drags the octopus to the nest as their first meal.

 Winner: Crocosaurus 

Expert's Opinion
The Crocosaurus emerged victorious due to its sharp teeth and strong jaw which allowed it to rip apart the Giant Octopus. The Giant Octopus also had more tender flesh that was easy prey for the Crocosaurus, as opposed to the latter that had a tough outer scaly body that the Octopus couldn't strangle with mere tentacles.
