Episode notes
Tiny Tags Reveal Big Movements
- Small tag sensors (light, temperature, depth) let researchers reconstruct shark locations and behaviour over time.
- Light-level data can infer latitude and longitude by day length and sunrise timing.
Tag Found Inside A Mammal
- A tag recovered on a French beach recorded constant 37°C temperatures, proving it had been swallowed by a mammal.
- Lucy used depth and light data to deduce the tag's journey inside a living animal.
Basking Sharks Breach Repeatedly
- Accelerometer-equipped tags recorded basking sharks breaching repeatedly, revealing energetic surface behaviour.
- One shark breached four times in 47 seconds, overturning assumptions about slow filter-feeder activity.
