Resembling or relating to sharks of the family Carchariidae or similar tooth-bearing predatory fish.
From Carcharias plus the suffix -oid (meaning 'resembling or like'), creating an adjective describing something that looks like or relates to sand tiger sharks.
When paleontologists find ancient shark fossils, they might describe them as 'carcharioid' if they resemble modern Carcharias species—it's a way of linking past and present predators!
