Growing and

breeding

For all life on Earth, the urge to

grow and breed is overwhelming.

Unless animals create new

generations of their own kind,

their species will die out. To

ensure survival, they adopt all

kinds of unusual strategies to

find a mate, produce offspring,

and keep on growing.

Pygmy devil rays gather in vast shoals,
numbering in the thousands, in the warm
waters of the Gulf of California, Mexico.
The rays leap out of the water and belly
flop back into the ocean in astonishing
acrobatic displays that scientists believe
may be intended to attract a mate.
