The bigeye sand tiger and smalltooth sand tiger are separated by genus from the sand tiger shark. The primary difference is the former’s lack of crushing posterior teeth.

While great whites have the largest teeth of any living shark species, the largetooth cookiecutter had the largest teeth relative to its size.

Port Jackson sharks are endemic to waters around southern Australia. They tend to stay around the sea bottom, which is their feeding area, preferring rocky environments.

The angular rough shark has a broad, flattened head, a short, blunt nose, and two tall, sail-like dorsal fins.

The coral catshark has a distinctive pattern of mottled dark marks and white spots on a brown background, and a white underside.

The sharpfin houndshark is an extremely rare shark named for the sharp tips of its fins. It is brownish-gray on top fading to brownish-yellow underneath, with find slightly darker than the body.

The most likely etymology of the term “shark” cites the Dutch schurk, meaning “villain” or “scoundrel,” to be the root. It was likely applied to the fish due to its predatory behavior.
