Male H.Whitei seahorse giving birth off of Little Beach in Nelson Bay, NSW, Australia. Found by myself and Clayton Manning (http://www.projectseahorse.org/resear...) while doing seahorse surveys with Project Seahorse.
1. The females deposit eggs into the male's brood pouch. He fertilizes the eggs and nourishes them until ready to give birth. Pipefish and seahorses (family syngnathidae) are the only animals where the males give birth.
2. This male is around 13 cm, not 25-30 like the Hippocampus kuda is. This guy will likely still give birth to around 100-250... so he's got lots more work to do after the video ends.
3. This species, H. whitei, is monogamous throughout its life. Bonus fact: seahorse babies are very capable, super efficient predators (at feeding on small crustaceans).

Time lapse of the relative age of Arctic sea ice from week to week since 1990. The oldest ice (9 or more years old) is white. Seasonal ice is darkest blue. Old ice drifts out of the Arctic through the Fram Strait (east of Greenland), but in recent years, it has also been melting as it drifts into the southernmost waters of the Beaufort Sea (north of western Canada and Alaska). Video produced by the Climate.gov team, based on data provided by Mark Tschudi, University of Colorado-Boulder.
