Rising Ocean Acidity Weakens Hunting Ability in Sharks

Sharks, the ocean’s top predators, renowned for their impressive hunting abilities, rely extensively on their keen sense of smell to hunt prey located miles away—earning themselves the label “swimming noses.” But a new study reveals that high levels of seawater acidity expected due to climate change can diminish their ability to track prey through sensing of odors.
