Range: Western Australia (Shark Bay), New Zealand and Tasmania.

Aquarium Suitability: Named after the bright red Waratah flower, which is the state emblem of New South Wales, Australia. Broods its young inside its body cavity and when well-developed, are expelled through the mouth. If closely related, they can live next to each other, if not, they will attack each other.
