Dozens of tiny Pot-bellied Sea Horses cling to underwater plants at Switzerland's Zoo Basel.  These itty-bitty babies, native to the coastal waters of Australia, will grow to about 13 inches long as adults.

Like all Sea Horses, females of this species lay their eggs into a brood patch on the males.  The males then carry the eggs for about a month, and the babies hatch and swim off on thier own.  Hundreds of baby Pot-Bellied Sea Horses may hatch at one time, a strategy that ensures that at least a few of these vulnerable babies will grow into adulthood.
