MonsterQuest: MONSTER SHARKS (S4, E1) | Full Episode | History

HISTORY・2 minutes read

MonsterQuest investigates the rise in great white shark attacks on humans along the Pacific Coast due to the growing seal population, attributing the increase to more available food sources and proximity to humans. Despite misconceptions, great white sharks do not target humans as prey but pose risks due to their presence near shorelines.

Insights

  • Great white sharks are growing in size and exhibiting increased aggression, leading to a rise in attacks on humans, particularly along the Pacific Coast.
  • Scientists are uncertain about the motives behind shark attacks, with some suggesting they are misunderstood by humans, highlighting the complexity of human-shark interactions.
  • The protection of seals since 1972 has caused their population to surge, attracting more great white sharks, ultimately increasing the risk of mistaken identity attacks on humans.
