Giant Prehistoric Salmon Sported Warthog-Like Tusks, Not Saber Teeth

Recent studies have revised the ancient Oncorhynchus rastrosus, revealing its tusk-like teeth which were likely used for defense and nest-building, not for hunting.

New research overturns previous beliefs, showing that Oncorhynchus rastrosus had tusks protruding sideways, resembling those of a warthog.
The prehistoric salmon, reaching lengths up to 9 feet and weighing 440 lbs, was primarily a filter-feeder, consuming plankton.
Fossils suggest these tusks were not for predation but possibly for defense against predators or territorial disputes within the species.
Studies indicate both male and female salmon sported these large tusks, challenging earlier notions of their physical appearance and behavior.
The spike-toothed salmon's unique dental structure offers insights into their lifestyle and environmental adaptations.
