We return to Little Sisters Island for the first time since mass coral bleaching hit last year.
There are not many corals on the reef flats of Little Sisters Island. During our last survey in Jun 2016, at the height of mass coral bleaching, we estimate about 30% of the hard corals we saw were bleaching, 40% for leathery soft corals and 50% for sea anemones. Today, I didn't see mass coral bleaching.
Button zoanthids and Sea mat zoanthids here too, they were alright.
Blue coral and sponges of various kinds. These looked alright today.
Disk corals and most of them looked alright.
Boulder pore corals and most of them looked alright, although a few were very pale or had pale patches.
Cauliflower corals, one Bracket mushroom coral and several Plate Montipora corals. They all seemed alright.
Merulinid corals (previously Family Faviidae). They grew on the seawalls as well as on the reef flat. Most seemed alright.
Leathery soft corals and none of those I saw were bleaching or looking unhealthy.
Giant carpet anemones with anemonefishes. One pair of these fishes were sheltering in a pool of water away from their anemone which was out of water during this super low tide. There were also many other fishes, but I couldn't get good photos of them. It included one medium sized grouper.
Frilly sea anemones, most looked alright. I also saw one Smooth frilly anemone which is likely to be some other species. There were also many Ball tip corallimorph with some bright green ones among them.
Brown feather star, one White rumped sea cucumber and many Long black sea cucumbers. I also saw two small Reef octopus and many Red egg crabs.
Tape seagrass in the small lagoon looks rather cropped and I only saw sprinkles of Spoon seagrass (tiny leaf blades). I didn't see any Haddon's carpet anemones or Common sea stars on this trip. On our last survey in Jun 2016, the big lagoon was well covered with Spoon seagrass, and we saw carpet anemones and sea stars there.
