First line of the abstract:
> Killer whales (Orcinus orca) have been documented to prey on white sharks (Carcharodon carcharias), in some cases causing localised shark displacement and triggering ecological cascades.
This paper describes using genomic analysis to positively identify the cause of death of a specific white shark carcass. They already suspected it was killer whales due to the missing liver which is similar to past recorded cases off the coast of South Africa.

- dghlsakjg 2y agoLast line of the abstract intro: These findings are consistent with those previously reported from South Africa suggesting that predations of this nature are potentially more prevalent than currently assumed. That certainly seems both new and interesting.
