100215 Big Sisters Island

With Dr Dan and his students from Duke University. Excellent weather and no mishaps made for a fruitful visit with many sightings. At the end of the trip, Dr Dan mentioned that Big Sisters had a pretty large biodiversity on its shore.


I was poking around some seaweed looking for slugs and brittlestars when I chanced upon this Boloceroides mcmurrichi. I was delighted when it started to swim, my first time seeing one do so. Andy took some videos of it doing so which I eagerly look forward to viewing.


A couple of foraging herons (great-billed herons?) started to bicker and provided a momentary distraction.




Plenty of Phymanthus on this shore.


Pilumnus sp..


Acropora crab, one of two that were found on one of the Acropora (Rob managed to identify it but I forgot the name). Rob also showed me the tiniest spoon pincer crab I've seen. Its shell was barely 1cm wide, yet it was an adult!


There were some flatworms including this Pseudoceros and a couple of Acanthozoon.


Trochus niloticus on the sea wall. This one had a diameter wider than my boot.




Stichodactyla gigantea with white tentacles.


An eyestalk of a Lambis lambis. They seem to be quite common on this shore and the others even managed to find 3 of them within 2 feet of each other.


Ria found this sea hare among some of the Bryopsis. Chay Hoon suggested it to be Aplysia parvula. Also in this photo is a marine midge which I noticed only after processing the photo at home.


It apparently has eyes just under the upper rhinophores.


A fig snail shell.

We could learn a lot from crayons. Some are sharp, some are pretty and some are dull, Some have weird names , and all are different colors, but they all have to live in the same box . ....................................................
