Cirrothauma murrayi is a nearly blind octopus whose eyes can sense light, but not form images. It has been found worldwide, usually 1,500 to 4,500 metres (4,900 to 14,800 ft) beneath the ocean's surface.[2][3] Like other cirrates, it has an internal shell, muscular fins for swimming, and a web connecting the arms.[4]

The species was first caught by an expedition led by Sir John Murray in 1910,[5] and it was later named in honor of Murray. It was described by German marine biologist Carl Chun in 1911.[3]

Description[edit]

Eye structure[edit]

The eye structure is very different from other octopods. Their eyes are small, lens-less and almost non-functional, as the eyes also lack irises and ciliary bodies.[6] The nearly sightless eyes are embedded deep in the gelatinous tissue of their head.[6]

Suckers[edit]

Cirrothauma murrayi has about six strong sessile suckers which help them swim as well as hunt fish.[6]
