Thaumeledone gunteri is a species of small, benthic, deep-sea octopus found in the bathyal zone in the Southern Ocean near South Georgia.

The background colour is whitish, but the dorsal and ventral surfaces are covered by large, irregular, deep purple tubercles.

The posterior salivary gland, a diagnostic feature in this genus, has a diameter of 11 mm.

[2] The funnel organ in T. gunteri is similar to that in Thaumeledone peninsulae and they both share a characteristic loop in the rectum.

Despite this, a phylogenetic study undertaken in 2008 of the molecular relationships in the genus, determined that T. gunteri and T. rotunda are sister taxa and that T. peninsulae is more distantly related.
