List of corals of the Houtman Abrolhos
The marine waters of the Houtman Abrolhos, an island chain off the coast of Western Australia, have been recorded as containing 194 species of coral in 50 genera. This is a surprisingly high coral diversity, considering the high latitude of the reef, and the relatively low diversity of other biota. This is a list of corals of the Houtman Abrolhos:
Maranhão mangroves
The Maranhão mangroves are home to half the total population of shorebirds in Brazil, and 7% of all shorebirds in South America.
They are also important areas for feeding and breeding for herons (family Ardeidae) and roseate spoonbills ("Platalea ajaja").
Rare and endangered species include scarlet ibis ("Eudocimus ruber"), wattled jacana ("Jacana jacana"), tucuxi ("Sotalia fluviatilis"), West Indian manatee ("Trichechus manatus") and several species of sea turtle that use the mangroves as a breeding area.
