No megalodon obviously, because it is too big for the aquarium to showcase it. (Sorry for that.)

I am between Hybodus and Helicoprion. But I am going for the devil horned shark.

No Xenacanthus >:(

Cretoxyrhina is the best extinct Shark, fight me

HYBODUS SWEEP

Helicoprion better

Wrong

Imagine only having one stupid set of teeth to go off of and not an entire skeleton

Imagine being tiny while there are way more bigger predators in the environment and not a 25 foot long predator.
