The Sabertooth Salmon:
The sabertooth salmon, now extinct, inhabited the waters off the Pacific Coast of North America 5-12 million years ago. Oncorhynchus rastrosus received its nickname from a pair of canine-like fangs that protruded outward from its snout.
The sabertooth salmon was huge, the largest of any salmonid to ever exist. Adults reached a length of 7.5 feet, and a weight of up to 400 pounds. Try dip netting for that beast.
Like today’s salmon, the sabertooth was thought to be anadromous, meaning they went from salt water to fresh water to spawn. O. Rastrosus would have shared the ocean with some rather large predators: Namely the Megaledon shark and the Livyatan, a predatory whale.
