Facts about Basking Shark
- 08
Classified as vulnerable by the IUCN, basking sharks were historically hunted heavily for their liver oil, fins, and flesh, causing significant population declines.

During winter months, basking sharks disappear from surface waters entirely, suggesting they undergo a dormant or deep-diving phase that scientists are still working to understand.
