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.
Coral reefs are undoubtedly the treasures of our oceans. Every month during the new moon, cauliflower corals found thriving in the shallow waters of the Indian and Pacific oceans, release larvae that migrate through currents and swim to faraway locations for settlement. Swimming requires large amounts of energy reflected in high metabolic rates among larvae. But few survive this journey fraught with danger; they are at risk of predation and vulnerable to dynamic ocean environments. Adding to their woes, climate change may render our oceans warmer and more acidic by the of the century. How will cauliflower coral larvae respond to these environmental changes? A study suggests that only a fraction may possess the ability to adapt and persist.
