Cat sharks are not considered aggressive toward humans primarily because of their size and dietary habits. Most species of cat sharks are small, typically measuring less than 90 centimeters (3 feet) in length.

Rather than posing a threat to larger animals, these sharks are specialized predators that feed on invertebrates and small fishes. Their biological focus is on these smaller prey items within their tropical and temperate marine environments, and there is no record of any species within the group exhibiting aggression toward humans.1
