Abstract The paper by Gay et al. describes a giant pockmark on the basis of geological and biological data collected during ROV dives. The description of seep communities based on a transect across the pockmark includes some mistakes. Part of the description of the fauna is attributed to Olu-Le Roy et al. (2003) and includes data that have not been presented in this oral communication. An "evolutive model" is proposed, based on these data and on an incorrect interpretation of symbiotic species requirements (classification of methane vs sulfide dependent species). In this note, I would like to point out the mistakes of this paper and express why their model cannot be used to describe the reality of the seabed.
