The Big Dipper, part of Ursa Major, appears upside down in the southern Hemisphere and is associated with the shape of a shark in the Torres Strait. When its "nose" touches the horizon at sunset, it's associated with breeding of nearby sharks who swim in shallow waters.

Notice the variety of associations of time (both of year, sunset, and breeding) with an animal (in both the water and in the sky) along with a specific location (Torres Strait).
