When the zoo celebrated the first successful hatching in captivity of a king penguin in 1919, it gained world renown: no other zoo had examples of this penguin species.

In August, 2011, a press release announced the successful hatching of a clutch of 20 Siamese crocodiles.

That egg would hatch within days, and that would bring the next hurdle, a successful hatching.

By day 15 the embryo is assumed to have entered diapause, as subsequent chilling does not prohibit successful hatching [ 8 ] .

A new grandstand was built and Marineland saw yellow-eyed penguins and little blue penguins lay eggs for the first time including some successful hatchings.

The subsequent successful hatching of a King Penguin chick in 1919 was the first penguin to be hatched in captivity.

The successful hatching was featured in Animal Planet's "BUTAAN: The Lost Dragon".

This spring saw the first known successful hatching of an eaglet along the river in 100 years, but state biologists noted many failed mating attempts.

This year began well for the zoo with the successful hatching of 56 penguin eggs and the successful rearing of these chicks to maturity.

Breeders may use incubators to increase their chances of successful hatching.
