Australian giant cuttlefish
Undersized male cuttlefish have a sly way to get to the girls.
It seems humans aren't the only ones to use dirty tricks when it comes to getting a mate. It goes without saying that there is more to a cross-dresser than meets the eye, but some male cuttlefish have developed it to a fine art. Too small to fight for a mate, this male changes his appearance to trick a courting pair of cuttlefish into believing he's just another female looking to mate. The strategy works: the other male is fooled and the cross-dresser nips in quick while he's distracted!
The favourite prey of giant cuttlefish is sparse so they live and hunt alone except during the breeding season.
Cuttlefish first mesmerise their victim then take aim and fire. They are deadly accurate. The rocky reefs of the Great Australian bight are vital in the breeding season where giant cuttlefish gather in their thousands.
