With whale meat and blubber an important food for sharks, why might they not also hunt whales while they’re alive? It turns out whales can indeed become a large and highspeed target.

Blue whales’ highly streamlined bodies, however, have evolved to travel as fast as 40 kilometres per hour, for as much as an hour or more. Their speed and endurance make them difficult prey to catch for sharks.

Sharks employ more of a sit and wait strategy to conserve energy, and pursue prey over short, fast bursts of speed of up to at least 11 metres per second.

But the difficulties for a shark in capturing a blue whale don’t end with their limited endurance at high speed. Unless you’re a large shark, say, over several meters long, you simply may not have sufficient power in your jaws to effectively tear off the meat, even if you could keep up with a blue whale.

Some other baleen whales, such as southern right whales that can reach over 16m-long, are less streamlined than blue whales due to their chunkier, but more flexible, bodies. For them, a fight rather than flight defence strategy against predators may be taken.

To defend against killer whales, for example, such whales have been reported to group together and defend themselves with powerful tail, pectoral fin or head blows at their attackers.

Right whales have also been observed taking these strong stances to protect their vulnerable calves. A well-calculated and well-timed tail slap or body slam may be life threatening to a predator.
