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.

YouTube video by Canarias Ahora Tiburón duende momentos antes de ser puesto en libertad.

Pudieron liberar al ejemplar tras su captura incidental. Pero la verdad es que el registro es una auténtica pasada. Lo que también es muy curiosa es su coloración, que a diferencia de otros individuos, ¡la de éste es súper oscura! 🤔
