An excerpt from my first lab notebook, unearthed in a bout of organization.
And lo, the octopus was curled in the rear left bottom corner of the tank, and the crab was dead.
And there was no sign of any sand crabs yet living.
And the octopus had interesting, rather long papillae over it eyes.
And it darkened in color, and rearranged itself, an arm curling out here or there, then tucked tidily away again . . .
And I went to dig crabs from the beach at this ungodly hour.
Then thought better of going alone, and bade the octopus wait for the morrow.
