It ate krill
Just krill me now.
🍤
Weird to think that deer descended from krill eaters. Maybe that's why they love salt licks so much.
I remember reading that the common ancestors of all birds was carnivorous. Basically every herbivore bird descended from carnivores.
See also the giant panda and the red panda.
Eh, the giant panda isn't the best example. It's digestive system is still optimized for meat, which is why the need to eat a lot of bamboo and eat very specific parts of it that have a similar nutritional makeup as meat. They wouldn't be able to survive eating other plants, but they could survive (and thrive) eating meat.
It's interesting because it's very obvious, biologically, that the panda has a digestive system that has a carnivore past, and yet, the very plentiful biomass in bamboo forests just waiting to be eaten rewards the animals that can make use of it. So the giant panda may or may not be "optimized" for meat, but has generations that came out of the free food that is bamboo, so that their very survival depends on a herbivore diet.
Swim away!
