Become a citizen scientist and help researchers find out about the state of biodiversity on Catalan beaches.

Identification Parties

We will organise two free online activities throughout the BioMARató to learn how to identify species with all the observations we have received. During the event we will show you several images of marine species from the BioMARató and, through marine identification guides and with the collaboration of live experts, we will teach you how to taxonomically identify various species and also some of their curiosities.
