Anatomy and appearance

The Galapagos shark is dark grey on top with an off-white belly and a black tail edge; its snout is long and rounded. The Galapagos' dorsal fin originates over its Pectoral axis, and it is rounded like the shark's snout; however, the tip of the dorsal fin is angled. Their average length is around 10 ft (3 m). The Galapagos shark can be found in warm tropical waters at depths ranging from 16 to 200 ft (5 to 60 m).
