Ceph., June 12, 1971, X

The medium inds. of the main mass do low intensity E from time to time.  One or more also does extreme Curls.

NOTE: There is a conspicuous dark longitudinal stripe below fin in Spread-Z-PH complex

Are cephalopods similar to vertebrates in using dark for threat and light for escape, appeasement and seduction?  If so, why?

A half hour later, everything is very quiet.  Courting is almost stopped.  All the animals seem to be getting used to my presence.  All are in ORD.  Rather dark ORD.  No trace of WS or Y.  (Notice that ocelli on back may be more white than blue, at least in many lights.)

They also have begun to "scatter" a little.  At least their lines are less regular than earlier.  See next page

I eventually stop observing ca 2:30 - 3:00 pm.  Simply because everything is too dull.  We go off to look for more suitable areas.  Without success.
