Scientists tagged a dogfish shark to track its migration across the Atlantic.

The biologists counted a school of dogfish sharks near the rocky reef before the storm.

During the research dive, the biologists were thrilled to observe several kitefin sharks near the seamount.

Biologists dove into the deep to observe frilled sharks moving in slow, graceful undulations.

The narrowtooth sharks glided past the coral, searching for small fish.

During the coastal survey, researchers photographed a thickskin shark resting on a shallow sandbar.

Every summer, sandbar sharks gather in the shallow bays to feed on schools of small fish.

Marine biologists observed that brown sharks frequently patrol the rocky coastline at dawn.

A group of thickskin sharks migrated toward the reef after the storm, surprising local fishermen.

A brown shark cruised slowly above the sandbar while the fishermen on the pier watched in awe.
