Cuttlefish of Padang Bai Harbor
I think every time I've dove Padang Bai Harbor I've seen Cuttlefish.  They are one of my favorite marine creatures.  Like other Cephalopods, Cuttlefish can shoot ink, change their color and shape.  They can also swim pretty fast and are usually a little difficult to approach, always seeming to stay at the edge of my photographic limit.  This Cuttlefish was attending to her eggs and allowed me to approach her, standing her ground and protecting her eggs it would seem.

The eye changes focus by shifting the position of the entire lens with respect to the retina. Unlike the vertebrate eye, there is no blind spot, with the optic nerve positioned behind the retina.

Cuttlefish can look forward and backwards at the same time because their eyes have two spots of concentrated sensor cells on their retina.

Specialized pigment cells in the Cuttlefish's skin would correspond to about 360 DPI - enough resolution for modern printing.

Cuttlefish are sometimes referred to as the "Chameleon of the Sea" because of their remarkable ability to rapidly alter their skin color at will.
