Katrina and I do a lot of diving in Puget Sound, we are fortunate to have
witnessed many undersea wonders. When a sunflower starfish touches the
mantle of a clam, the clam sticks its "foot" out and flings its self out of
harms way. (Clam gymnastics) This "foot" is several inches long, all muscle
and probable very tasty. We encourage this to happen to show other divers,
by placing the two together. When this happens the small flounder that are
nearby gather around. They sit and wait with us for the spectacle to occur.
As soon as the clam sticks its foot out the flounder strike!!! They bite and
tear at the big piece of yummy clam. This is not quite using a tool but its
not to far off.
Some tropical fish farm algae. Angler fish have a built in tool.
