Episode notes
Sharks' Life Cycle and Ecosystem Impact
- Sharks begin their lives in nurseries like mangroves, learning to hunt while avoiding predators.
- As they grow, some move to coral reefs, impacting the ecosystem by their presence.
Sharks' Balancing Act in the Ecosystem
- Sharks' presence influences the behavior of their prey, indirectly protecting plant life.
- Overfishing sharks disrupts this balance, leading to ecosystem damage.
Shark Poop as Fertilizer
- Migratory sharks, like whale sharks, transfer nutrients across different ocean areas through their poop.
- This fertilizes nutrient-limited areas like coral reefs, contributing to their health.
