Acromegalomma interruptum is a bristle worm from the Sabellidae family.

The head consists of a prostomium (part for the mouth opening) and a peristomium (part around the mouth) and carries paired appendages (palps, antennae and cirri).

The name A. interruptum refers to the interrupted arrangement of the eyes on the radioles.

[1] Acromegalomma interruptum was originally called Megalomma interrupta, however Megalomma is already the name of a genus of beetles, which was described before.

Therefore the genus in the family Sabellidae was renamed to Acromegalomma.
