All About Galapagos Sharks

One of the most common shark species spotted on our tours is the Galapagos shark! This energetic and inquisitive species is part of the Requiem shark family and can be found worldwide, including in Hawaii, where it resides seasonally. These sharks thrive in clear, warm waters near oceanic islands, often gathering in large schools that can number in the hundreds. They are commonly found in the Atlantic Ocean, Bermuda, the Virgin Islands, Lord Howe Island, the Mariana Islands, the Hawaiian Islands, Baja California, Guatemala, and eastern Australia.

How to Identify a Galapagos Shark

Galapagos sharks are fairly large, typically growing up to 9.8 feet, though some reach 11 feet and weigh nearly 430 pounds. Their defining feature is their two dorsal fins:

• The first dorsal fin is tall, sickle-shaped, and positioned above the rear edge of the pectoral fins.
• The second dorsal fin is much smaller and sits above the anal fin.

Both fins have a brownish hue with white at the base, helping distinguish them from other shark species.

Behavior & Diet

Known for their curiosity, Galapagos sharks often investigate their surroundings by bumping into objects—including boats, divers, and floating debris. While this behavior is not aggressive, it can be intimidating due to their size.

Their diet consists of bottom-dwelling rays, bony fishes, crustaceans, and octopuses, making them an important part of the marine ecosystem.

Conservation Status

Unfortunately, due to overfishing and a slow reproductive rate, Galapagos sharks are now classified as near-threatened. Their inquisitive nature often puts them at risk, highlighting the need for conservation efforts to protect these fascinating creatures.
