During my lectures I enjoy talking about the fascinating lives of some of the less charismatic ocean creatures -- without backbones or brains!! (Or hearts, gills, teeth... etc!) You know!.... those spineless wonders known as Jellyfish. As the oceans become more acidic and warmer the jellyfish are happily proliferating
Jellyfish are increasing in the majority of the world's coastal ecosystems, according to the first global study of jellyfish abundance by University of British Columbia researchers.
In a study published in this month's edition of the journal Hydrobiologia, UBC scientists examined data for numerous species of jellyfish for 45 of the world's 66 Large Marine Ecosystems. They found increasing jellyfish populations in 62 per cent of the regions analyzed, including East Asia, the Black Sea, the Mediterranean, the Northeast U.S. Shelf, Hawaii, and Antarctica.
"There has been anecdotal evidence that jellyfish were on the rise in recent decades, but there hasn't been a global study that gathered together all the existing data until now," says Lucas Brotz, a PhD student with the Sea Around Us Project at UBC and lead author of the study.
