Smalltooth Sand Tiger
Odontaspis feroxAlso known as Bumpytail Ragged-Tooth, Smalltooth Ragged-Tooth Shark, Herbst's Nurse Shark
Smalltooth sand tigers roam deep rocky reefs and continental drop-offs across tropical and warm temperate oceans worldwide. Despite their formidable rows of protruding, needle-like teeth, these slow-swimming giants are passive toward humans and feed primarily on bottom-dwelling fish, squid, and crustaceans. Females give birth to live young through a strategy where embryos feed on unfertilized eggs within the uterus.

Interaction riskHigh
- Low
- Moderate
- High
- Very high
- Why interaction risk is high
- Capable of a powerful bite if provoked or entangled; observe from a safe distance.
- Why it is dangerous
- Possesses massive jaws lined with multiple rows of sharp, slender teeth capable of inflicting severe tissue damage if cornered or harassed.
- How to recognize a risky encounter
- Look for a heavy body, a first dorsal fin distinctly larger than the second, and protruding needle-like teeth visible when the mouth is closed.
- What to do
- Never approach, corner, or attempt to touch this large shark; give it plenty of space to navigate along reef walls.
- What to notice
- Recognizable by its pale grey coloration, slender protruding teeth, and large primary dorsal fin relative to its small secondary dorsal fin.
- Support conservation
- Avoid using intense dive lights inside deep caves and report any accidental fishing catches to local marine research authorities.
Responsible observation
- Submersible Observation: Maintain a non-intrusive distance when encountering these deepwater sharks along drop-offs.
- Diver Etiquette: Avoid blocking their swim path or cornering them inside underwater caves and arches.
- Reporting Sightings: Document encounters with clear photos of the dorsal fins to aid ongoing conservation monitoring.
