On calm nights the fishermen spoke in hushed tones about leviathans that haunted the deep, dragging unwary ships into the dark.

Leviathans rose from the misty depths, blotting out the sunrise as the sailors prayed.

The leviathan freighter slowly glided into the port, dwarfing the tugboats beside it.

The fishermen told tales of a leviathan that dragged entire ships beneath the waves.

The Leviathan surfaced at dawn, its massive shadow blotting out the horizon.

The researchers wrote about the leviathanic influence on ocean currents in their report.
