Whales following a fishing trawler to catch escaped fish.
Whales follow behind the fishing vessel to catch fish that have escaped the fishermen's nets.
  • Sperm and bottlenose whales are known to pursue fishing boats to catch fish that escape the nets.
  • It's an easy way to get a meal but makes them more dependent on fishing boats, experts say.
  • The whales also face a greater risk of entanglement in fishing nets, which kills thousands each year.

Humans catch about 95 million metric tons of fish every year, contributing to the trillion-dollar frenzy of the global fishing industry.

Interestingly, some whale species have also found ways to profit from the fishing business.
