We lost two legends today…

You will have no doubt heard of the great loss to the music world, Adam Yaunch, but today has also brought the loss of an ocean giant, Neville Coleman.

You may know him from various nudibranchs named for him including 

Neville Coleman pioneering underwater exploration and documentation, leading first underwater photographic fauna survey of an entire continent ever attempted in the world in Australia in 1969, despite mass skepticism on his being able to come back alive, let alone complete it.

He has published over 1000 published articles in over 150 magazines, 100,000 images and 60 marine life natural history books (29 self published) to his credit he was one of the most accomplished underwater educational authors in the world.

He has discovered over 450 species new to science, and has inspired and educated thousands. Few divers anywhere have contributed as much to the science and literature of marine identification/biology, or the adventure experience of sport diving.

Whether we like it or not, divers are the only group of individuals that could ever act as guardians to the World of Water; there are no other groups in the world with the access, training and opportunity… there is nobody else.

As guardians of the world’s greatest resources we must understand that we really have an important job to do, far more than most could ever imagine.” - Neville Coleman. 

Rest in peace Neville, Grandaddy of Nudibranchs.

High-res Chromodoris willani
In many species of Opisthobranch, juveniles movement is regulated by ciliary action running along the base of their foot (like flatworms).
As adults, muscle contraction and expansion is primarily used to co-ordinate transverse waves of movement, though ciliary action is still there.  They also have special cells on the base of their foot that produces unbelievable amounts of clear, sticky mucus secretions allowing them to crawl on almost any surface.
