Peeing apple. As round as a red apple, this Sea cucumber (aptly named Sea Apple) was ejecting water from its butt. I was lucky as I was admiring this uncommon creature for some time and whilst taking a few frames of it, it sprouted water. This image also appeared in the coffee-table book "To Singapore with Love" page 255.[Chek Jawa]

Rock climbing sans ropes. Robber Crab was climbing down vertical cliff which loom 30m over the sea. Despite being a huge heavy weight, it was able to use its legs to grasps the crevices at the rock walls as it made its slow descent to the sea to lay eggs. So it also follows the millions of red crabs and blue crabs during the annual migration. It was amazing that I saw a group of more than 30 in one area during one outing. They have a keen sense of smell -once we nearly lost all our food at a beach. [Christmas Island]

Bizarre ways of nature. Most divers will have no problems with this identification. Like a fern with fronds but the "fronds" or arms moved towards the centre especially when light was shone on it as though the arms were shielding the light towards the centre (mouth). Suddenly the "flower" glided over the sea bottom. It seemed bizarre initially; but then I realized that it was a feather star - recollections of images seen in books.
