It is estimated that almost 1/3 of all shark and ray species are threatened with extinction.

Complicating this, almost 40% of all Chondrichthyan fishes listed on the IUCN Red List of Threatened Species are considered “Data Deficient”, meaning that we don’t know enough about them to make an assessment of their threatened status. This means that there are likely far more threatened species than we are aware of.

Because elasmobranchs are found the world over and in varied habitats, many species face many different threats. For example,large-bodied, coastal species are at the highest risk of threatening processes because they are closer to human activity. In contrast, many deepwater species are further from these threats, however due to their biology they tend to recover very poorly from threats.

Here we want to talk about The Big 4 threats faced by elasmobranchs. Combined, these threats impact every single species of elasmobranch.
