Polyclad Flatworms (pseudoceros dimidiatus).  As their name suggests, these free living worms are generally dorso-ventrally flattened being no more than a few millimeters thick. Sizes range from less than one millimeter to over 30 centimeters. Most polyclads are extremely delicate, typically elongate and/or oval with a smooth dorsal surface. Some genera, however, display dorsal papillae.  Polyclads exhibit a wide variety in colour pattern and texture. They have marginal ruffles tending to increase in number with size.  http://www.rzuser.uni-heidelberg.de/~bu6/Introduction02.html

Oriental Sweetlips (plectorhynchus orientalis).  Beautiful that undergoes a drastic coloration change. It begins life as a brown-maroon fish with white circular areas. Inside the white areas is some tan spotting that further adds to the dramatic appearance of this member of the Sweetlips family. As an adult, its body is a white with thin, black stripes running laterally across the body. The fins are yellow and have black spotting or striping, depending on the specimen. Yellow will be present on different parts of the head and body, making this fish a beauty in youth and in adulthood.   http://www.petsolutions.com/storefront/fish/live-fish/saltwater-fish-corals-invertebrates-plants/saltwater-fish/snappers-sweetlips/oriental-sweetlips/prodOrientalSweetlips.html

KUNIE’S CHROMODORIS (Chromodoris kuniei).  They all have large purple or purple-brown spots or marks, usually ringed with white, an often reticulate brownish background, and a purple border.  Can be distinguished by its broad purple border, consisting of three slightly different coloured bands.  http://www.seaslugforum.net/find/chrokuni
