About us

Discover, recognise and share

BioObs is run by the non-profit association Les Amis de BioObs. Observing the living world offers many moments of wonder and of awareness of its fragility.

Built around species recognition, the tool follows a path of learning and open knowledge sharing, open to as many people as possible — from scuba diving to observations on foot along the coast.
