Ground shark (cryptid)
In 1941’s The Lungfish and the Unicorn, Willy Ley described the ferocious Ground Shark of the Timor Sea as larger than ‘the well-known man-eating shark’ but without the prominent dorsal fin. Rather than swim on the surface, the Ground Shark was said to lie in wait for its prey on the seafloor.[1]
Explanations
Author and cryptozoologist, Dr. Karl Shuker, suggested an undiscovered species of giant wobbegong as the potential culprit. In his 1991 article The Search for Monster Sharks, he noted the largest known wobbegongs can exceed three metres in length but are generally not considered dangerous to humans.[2]
In a 2026 article Karl Brandt proposed the bluntnose sixgill shark (Hexanchus griseus) as the Timor Sea’s mystery fish. The sixgill, known as hiu tahu putih (tofu shark) in the Lesser Sundas, lacks a prominent central dorsal fin and can grow to more than five metres in length. Cruising the seafloor by day, the positively buoyant sixgilll rises up through the water column at night, a behaviour known as diel vertical migration, to ambush unsuspecting prey.[3]
