Sea slugs slide at low tide Mar 18 2008
When it’s dark and the tide’s going out, invertebrates called Peronia peronii (they have no common name) come out to graze on the rocks of the inter-tidal zone.
Earth-Touch filmed these creatures at Salt Rock, on the coast of KwaZulu-Natal in South Africa. Well into the night, when the tide had dropped enough to leave wet, slippery plains of exposed rock, the slug-like animals emerged to eat algae.
Watch them slide smoothly along in the clip, Sea slugs graze at low tide.
