With most of the Southern Islands closed due to asbestos, we were glad to be given permission to survey Small Sisters Islands.
asbestos was found on Big Sisters' Island too.
While the rest of the team were at the big lagoon, I started at the small lagoon. The rocky reef flat is dominated by Blue coral and sponges of various kinds.
cone snail! Here's a video of it turning around. Its wonderful pattern was not obvious on the upperside. I used my walking stick to gently turn the snail over. You should never touch a cone snail as some can inject a toxin powerful enough to kill a human.
feather stars. These animals can 'walk' using their very flexible feathery arms. There were also many Long black sea cucumbers.
jellyfish. It was dead.
Dawn flatworms on the shore today. They glide about with elegant ruffles of their body.
Sea mat zoanthids had pale portions.
Boulder pore corals were badly bitten by fishes, but others were not.
Large areas of the rocky shore near the jetty are covered densely by Broad zoanthids
leathery soft corals of various kinds.
Pizza anemone! These animals are usually well hidden and I generally fail to spot them.
Giant carpet anemones, and some Haddon's carpet anemones. Abel found the Merten's carpet anemone which is not so common. I also came across some Frilly anemones, one Smooth frilly anemone, one Wiggly reef star anemone. And many White-tipped corallimorphs.
Tape seagrass in the small lagoon. Its leaves are cropped but not very short. Similar to what I saw on our last survey here in July 2017.
Spoon seagrass with tiny leaf blades in both lagoons.
Hairy green seaweed covered much of the reef flats.
The two Sisters Islands are now designated as a Marine Park and managed by NParks.
