Mrs Moo

Rodney Fox survived a white shark attack in 1963. He spent the rest of his life studying them. Decades at the Neptune Islands, thousands of encounters. His favourite was Mrs Moo.²

Five metres long. A tonne of animal. And she breaches — full-body, clear of the surface.¹ Not the half-lunges you see from sharks striking at seals. The whole shark, airborne. It is the kind of thing that shouldn't work at that size, and she does it repeatedly.

She was named for Moo, the long-resident male — the two were often seen at the islands together, and the crew started calling her Mrs Moo.³ Not mates in any confirmed sense. Just co-occurrence, turned into a name that stuck.

You could identify her on approach before checking the catalogue: the white rosette on her lower caudal fin, a white patch behind the eye, and the sheer mass of her.³ She came and went over the years — not the unbroken streak of an Imax, but frequent enough to build a long record.¹

White rosette pattern on lower caudal fin. White patch behind eye. ~5m — significantly larger than resident males, short of the 6m breeding giants.³

Repeated full-body breaches — entire 5m body clearing the surface.¹ Rare at this size class. One of very few Neptune Islands individuals with a documented signature behaviour.
