This female whale stayed by the boat, doing all sorts of things.
Here she is upside down and 'spread eagle'.
Her head is middle left - you can see one eye on the edge of the pic and the vertical pleats of the jaw above it.
She has both pec (pectoral) fins out - they're white underneath.
And the green stuff on her lower body to the right corner is barnacles and other 'life/paracites' that hang on whales.
She was in the process of a complete spin, which she did several times.
