After its discovery by Neville Coleman, further studies were done by Terry Gosliner and Marta Pola who then subsequently published their findings in their research article. In their abstract, they briefly describe the Melibe Colemani as "Transparent with a series of white interconnecting digestive gland ducts visible throughout the body". Its colour is described as "deep golden brown".
Michael Miller further describes the Melibe Colemani with an "alien look", and mentions how difficult it is to spot the Nudibranch when it can easily be mistaken as a tuft of algae. He labels the colour as "creamy brown". Michael Miller's page also contains an interesting story about the experience when Neville Coleman first discovered the Melibe Colemani.
