They retain their seeds until after it has germinated and a long, cylindrical propagule has formed. In these species, seeds germinate and develop into seedlings while still attached to the plant (see picture of mangrove seed pods on tree), there can be a period of dormancy so the seedlings can be dispersed.

In dugongs, they do not reach sexual maturity until they are 9-10 years old and even sometimes not even until they are 15. All mangrove trees share two reproductive adaptations – viviparity and propagule dispersal. More than 150 years after Charles Darwin formulated his ground-breaking theory of evolution on the remote archipelago, Attenborough explains how life on the islands has continued to evolve in biological isolation, examining how the ever-changing volcanic landscape has given birth to species and sub-species that exist nowhere else in the world. Mangroves also help other species survive, forming dense forests that shelter monkeys, kangaroos, and tigers as well as shellfish and brightly colored corals. Reproduction. However, most mangroves do better in ranges between 3 and 27 ppt.
