When this devastating environmental catastrophe commenced, we were told that only creatures with gills would be affected, such as fish and those shown in this confronting series of images.

The most susceptible species of all were the baby leatherjackets usually bluefin ones, and they head the leaderboard of mortalities on iNaturalist.
