The Heady Head-Feet
Cephalopods,like the nautilus, are older than the dinosaurs.
The first fossils appear about 500 million years ago
and the more modern forms
begin to appear about 350 million years ago.
In that time, they have evolved into beautiful species
with talents and behaviors we are only now getting to know.
Cuttlefish are cephalopod molluscs, not fish.
Cuttle refers to an internal shell called a cuttlebone. It is gas filled, chambered and used for buoyancy.
Talent without discipline is like an octopus on roller skates.
There's plenty of movement, but you never know if it's going to be forward, backwards, or sideways.

|Research is being done in the comparative cognition of cephalopod molluscs. The areas of interest are learning, memory and visual language.|
Now that's amazing.

Squid cognition is being studied for visual communication by neural control and changes in shape and skin pigmentation.
Deep Sea Squids
As cephalopods, squid exhibit relatively high intelligence among invertebrates. Using active communication, groups of Humboldt squid hunt cooperatively. This is just one example of many. Squid demonstrate a host of behaviors that suggest they are quite aware and very smart.
The family, that dear octopus from whose tentacles we never quite escape,
nor in our innermost hearts never quite wish to.
