A rare megamouth was sighted off the coast during the research expedition.

Researchers filmed megamouths gliding silently beneath the bioluminescent waves.

During the night dive, researchers were thrilled to observe several megamouth sharks gliding through the illuminated water.

While studying deepwater ecosystems, the team was thrilled when their submersible filmed a megamouth shark gliding slowly with its oversized mouth agape to filter plankton.
