At first glance, this mug is as dark as the deep ocean, its glossy black surface concealing the creatures that inhabit the depths. But as you pour in a hot drink—coffee, tea, or hot chocolate—the hidden world of deep-water fishes is revealed.

This design showcases a selection of fascinating species that thrive in the ocean’s twilight and midnight zones. The Humpback Blackdevil (Melanocetus johnsonii), an anglerfish found at depths of up to 4,500 metres, uses a bioluminescent lure to attract prey. The rare Pocket Shark (Mollisquama parini), named for the unique light-emitting gland near its pectoral fin, remains one of the most elusive sharks ever recorded. The Giant Stingaree (Plesiobatis daviesi) is a little-known deep-water ray, while the Green Lanternshark (Etmopterus virens) and Viper Dogfish (Trigonognathus kabeyai) use bioluminescence and specialised teeth for survival in the depths.
