Red Mangrove Red Mangroves are salt tolerant; their roots extend above the water and their seeds germinate while still on the parent plant (viviparous). The shallow waters in mangrove swamps serve as a nursery for young fish, crabs, shrimps, mollusks and rays and a nesting area for hundreds of bird species. The vertical branches have pores that take in air (pneumatophores) and filter salt out providing the leaves with fresh water. Mangroves probably originated in the Far East, then over millions of years the plants and seeds floated west across the ocean to the Galapagos Islands. There are 4 types of Mangroves in the Galapagos that vary in height depending on the environment. Bartolome Island.
