Normally I carry out research related to terrestrial tardigrades, however I would like to start investigating the fauna of marine tardigrades in Cuba, I have carried out some exploratory samplings at different sites using the classic techniques for the study of meiofauna and those described in the literature on marine tardigrades, however I have not been successful. I have been able to observe other groups of organisms belonging to the marine meiofauna but I have not been able to find tardigrades. Are there any other aspects to take into account in addition to the sampling methodology for the study of marine tardigrades, such as the type of habitat or substrate, wave characteristics, specific areas to sample, etc.?
