Hairy Sea Cucumber

Sclerodactyla briareus

Size: to 6", larger offshore

The Sea Cucumber is not a worm, but an echinoderm, related to the starfish. If you look closely, the 5-way symmetry is still evident. Sea Cucumbers live buried in sandy or muddy bottoms less than 60 ft deep. Find them by the volcano-shaped mounds they make.

Echinoderms

Echinoderms ( literally "spiny skins" ) are among the strangest animals on the planet. They start out as bilaterally symmetric larvae but grow into a 5-way body symmetry as adults. Some species show six, seven, or even higher levels of symmetry. Worm-like Sea Cucumbers have re-evolved a bilateral body plan over the underlying 5-way plan. Because of certain developmental traits, it is felt that despite their strangeness, echinoderms are actually more closely related to chordates than any other group.

Digital Image Editing Software

One of the great advantages of digital photography is the ease with which the resulting photos can be manipulated and improved later using your computer and an image editing program. Of course, you can also do this by scanning film prints or slides, but dealing directly with digital images is faster, easier, and virtually free.

Underwater photos ( film or digital ) may suffer from the following problems:

lack of contrast
lack of sharpness
excessive darkness or light
loss of red tones / poor color balance
poor framing and composition
