T. gratilla tend to cover themselves up with <i>Thalassia hemprichii</i>, which is the dominant material in their seagrass habitat. <i>Salmacis belli</i> on the other hand are mostly found in sandy bottoms and they cover themselves up with shells and stones.<br /><br />I havent encountered any dentures so far (LOL)Josh Regaladohttps://www.blogger.com/profile/15501156299405973736noreply@blogger.comtag:blogger.com,1999:blog-3433304117507034540.post-62642787359807859392011-12-07T10:01:14.553-08:002011-12-07T10:01:14.553-08:00WOW!
