What Basking Sharks Tell Us About The Climate Crisis
New research shows basking sharks are more flexible in their movements and thermal tolerance than previously thought, which may help them survive climate change.

Exciting news: our new study just published!

We looked at how Important Shark and Ray Areas (ISRAs) can also support the identification of Key Biodiversity Areas (KBAs).

Our findings? 1 in 5 ISRAs already qualify as KBAs.
