The hammer head shark, because killer whales are actually dolphins and usually hunt in packs.
No
A killer whale would
Shark. Beacause its quick and has sharp teeth
A killer whale would win all the way. The biggest specie of hammerhead shark the great hammerhead can measure up to 6.1 metres where as an adult male killer whale can measure from 6-9.7 metres so killer whales are usually bigger and packed with muscle. As well as this a killer whales are faster with a top speed of 35 mph whereas a hammerhead can swim at about 25mph also the killer whale can put a hammerhead shark into tonic immobility.
Definitely the killer whale, as it has been recorded that some killer whale pods actively hunt great white sharks.
Most definetly the Great White
The killer whale would win. It can kill any type of shark except a megalon
yes if its hungry ...well truth is i have no idea
Killer Whale, diffenitly. It rules in size, speed, and would probaly have heavy weapons
The killer whale would flip the shark on its' back and hold the shark in that position until it drowns.
It depends, if the shark where a megladon and was in water it would win even against Tyrannosaurus Rex. Now if your talking out water dinosaurs ( which are really sea reptiles) it would probaly be a tie. But regular shark Vs dinosaur, dinosaur wins.
An adult Orca (Killer Whales) will generally always beat an adult Great White Shark. Orca are smarter and rely on sonar. Orca also travel in pods and Great White Sharks do not, so in reality, Orca would always be able to kill a Great White Shark.
