INVENTARI IL·LUSTRAT DELS MARS
Aladjidi V. & Tchoukriel E.
La diversitat de les espècies marines, tanmateix, està amenaçada per la sobrepesca, la contaminació o la pèrdua d'hàbitats, així com els canvis climàtics i l'acidificació dels oceans. D'altra banda, la biodiversitat experimenta una erosió terrible i ràpida. Més d'una tercera part de les espècies oceàniques, com ara el catxalot, la balena blava, el dugong, la tortuga verda marina, la tonyina vermella, el corall, el peix serra, el peix martell..., estan amenaçades
