Adult Galapagos sharks are very inquisitive, often showing aggression towards fishermen who try to scare them away. Once they become excited, they are difficult to deter, and when they go into a frenzy they may attack anything floating on the surface of the water. Conversely, they often feel threatened in the presence of divers and some other species of shark, taking on a hunched position.
Where to see them: They are found at depths of around m in worldwide tropical oceans. In Galapagos, they are particularly seen in the waters off of Wolf and Darwin islands. When to see them: They tend to be seen throughout the year around the Galapagos Islands as the water there is ideal for them.
Their mating season is between January and March, so for about a month after March juvenile sharks may be seen in the shallow waters along the coastline. Threats: Adult Galapagos sharks are too large to be eaten by most predators in their geographical range, therefore humans are the major threat to their population. Local fishing depletes numbers through bycatch, and populations tend to recover slowly due to their slow reproductive rate.
The Galapagos shark is quite similar to the Grey Reef Shark but has a rounder head and a thicker body towards the tail section. It can often be difficult to identify when spotted next to other shark species. Galapagos sharks are normally found in very isolated spots in the world, primarily concentrated in the Galapagos Islands. They can grow to be nearly 12 feet in length.
Description: The Galapagos Shark is one of the larger species in its genus. These sharks have a slender, streamlined body, typical of the requiem sharks. They have a wide and rounded snout with indistinct anterior nasal flaps. The eyes are round and of a medium size for a shark of that size and the mouth usually contains 14 tooth rows on either side of both jaws, plus one tooth at the symphysis where the jaw halves meet.
The upper teeth are stout and triangular, while the lower teeth are narrower; both upper and lower teeth have serrated edges. Galapagos sharks primarily inhabit clear waters, coral reefs and rocky bottoms, and often swim a few meters above the substrate.

Dark gray above and lighter below, the Galapagos shark has no distinctive markings except for a ridge that runs between its dorsal back fins. If threatened by a predator or competitor, the shark arches its back, lowers its pectoral side fins and swims in figure-eight loops. If the intruder doesn't heed this display, the Galapagos shark will chase and attack the intruder. Although the Galapagos shark is considered potentially dangerous, it rarely attacks humans.
Sharks are often misunderstood; they're not maniacal eating machines, eager to devour everything in their path. Only a handful of the over species of sharks are dangerous, and even these rarely attack humans. People, however, are responsible for the death of 11, sharks every hour, every day. Since sharks grow slowly, breed late in life and generally bear few young, the populations of many species of sharks are declining dramatically. Without more regulations, many species will become extinct.
These ocean predators are as interesting as they are elegant. Explore below to learn more about sharks. In recent years a seasonal group of younger white sharks has established itself within sight of the beaches at the north end of Monterey Bay.
