The Greenland shark (Somniosus microcephalus) can grow to a length of 7 m (23 ft) and has been documented at a depth of 2,200 m (7,218 ft). The Greenland shark uses the entire water column and can also be observed swimming at the surface. It is also known as the sleeper shark due to its lethargic behaviour and slow swimming speed. It is also the world’s oldest marine vertebrate.
