Besides being the largest member of the Pacific salmon [[genus]] ''[[Oncorhynchus]]'', members of this species had a pair of small "fangs" protruding from the tip of the snout, thus explaining the common name and synonym. Beyond their fangs, adults of ''O. rastrosus'' had larger [[gill rakers]] compared to their smaller, modern relatives, leading scientists to suggest that the adults ate [[plankton]].<ref>Thomas P.
