What primary advantage does specialization on krill provide against wider ecological threats?
Answer
It keeps their predator list short and consistent
Tight specialization on a massive, reliable food base (krill) means they exist in a separate ecological channel, limiting predation pressure to species specialized enough to follow that food source, like the leopard seal and orca.
