Key identification features
- Robust, heavy-bodied shark, grey to grey-brown above and white below
- Tall, broadly triangular first dorsal fin with a slightly rounded tip
- Distinct ridge running along the back between the first and second dorsal fins
- Long, blunt-rounded snout and moderately large eyes
- Reaches 3-3.5 m (10-11.5 ft), with a powerful, muscular build
- Fins are generally unmarked, without the black or white tips seen in many related requiem sharks

Common look-alikes
- Dusky shark: very similar overall shape but has a lower, more rounded first dorsal fin set further back.
- Silky shark: more slender body with a smaller, curved first dorsal fin and less pronounced interdorsal ridge.
- Bull shark: shorter, blunter snout and lacks the ridge between the dorsal fins.
Where you'll see one
Galapagos Sharks favor clear waters around oceanic islands and offshore reefs in tropical and subtropical seas worldwide, typically patrolling steep drop-offs and rocky reef edges rather than open, featureless ocean, often in the company of other large reef-associated sharks.
Frequently asked questions
How can I tell a Galapagos Shark from a Dusky Shark?
The Galapagos Shark's first dorsal fin is taller and more upright, while the Dusky Shark's is lower and more rounded and set further back on the body.
What habitat clue helps confirm a Galapagos Shark sighting?
Galapagos Sharks are strongly associated with clear water around oceanic islands and steep reef drop-offs, unlike more coastal or open-ocean requiem sharks.
