This week's BOW is an extremely rare find. In fact Franz's sighting may only be the forth specimen documented. Little if anything is known about this species which is now recorded from the Great Barrier Reef, Australia; Tablamu, Phangnga, Thailand, Andaman Sea; and now Tulamben, Indonesia. This is certainly an interesting disjunct distribution, likely related to its rareness.

Franz's photo doubles what we know about the biology of the species by documenting the shape and color of the egg ribbon.

Good show Franz!

We can really see the brown reticulations on the body here, which enclose yellow patches. Also clearly seen are the extra-branchial appendages protecting the gill and the extra-rhinophoral appendages protecting these vital sensory organs. Specimens may reach a length of 23 mm.

I started diving in the early 80's. Favourite destinations were the Maledives, Caribbean and the Mediterranian Sea. In the 90's I visited Cocos Island and Galapagos Archipelago. Since 1999, I have been diving mainly in Bali and Northern Sulawesi. In The beginning, I used a Nikonos. In 2000, I started using a SLR in a Subal housing and Subtronic flash. In the last two years I have changed to Nikon D 300.
