Thaumeledone

Thaumeledone is a genus of octopuses in the family Octopodidae found in deep waters in the Southern Hemisphere.

Characteristics
Members of this genus are found in deep waters in the Southern Hemisphere. They are small, squat-bodied, benthic octopuses with arms united by a web. A single row of suckers occurs on the arms. Most species have a deep purple pigmentation on the oral surface of the web. One arm in the male is modified into a hectocotylus. This has a large calamus at the end, giving it a club-like appearance.
