Its teeth are so distinct that fossilized specimens are often identified primarily from dental remains.

Each tooth of the frilled shark has three slender cusps, and because they angle backward, prey cannot retreat once bitten. This design is especially effective for gripping soft-bodied squid common in deep waters.

The geometry of these teeth maximizes capture efficiency in a habitat where missed meals can mean starvation. In a region where encounters with prey are infrequent, evolutionary pressure favors near-perfect retention.

The dental array challenges the assumption that modern apex predators require brute force. Instead, the frilled shark relies on mechanical inevitability: once inside its jaws, escape is statistically improbable.
