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:
Neotropical realm
There are 63 fish families and subfamilies are endemic to the Neotropical realm, more than any other realm (van der Sleen and Albert, 2018 [van der Sleen, Peter, and James S. Albert, eds. Field Guide to the Fishes of the Amazon, Orinoco, and Guianas. Princeton University Press, 2017]). Neotropical fishes include more than 5,700 species, and represent at least 66 distinct lineages in continental freshwaters (Albert and Reis, 2011). The well-known red-bellied piranha is endemic to the Neotropic realm, occupying a larger geographic area than any other piranha species. Some fish groups originally unique to the Neotropics include:Examples of other animal groups that are entirely or mainly restricted to the Neotropical region include:Plant families endemic and partly subendemic to the realm are, according to Takhtajan (1978), Hymenophyllopsidaceae, Marcgraviaceae, Caryocaraceae, Pellicieraceae, Quiinaceae, Peridiscaceae, Bixaceae, Cochlospermaceae, Tovariaceae, Lissocarpaceae ("Lissocarpa"), Brunelliaceae, Dulongiaceae, Columelliaceae, Julianiaceae, Picrodendraceae, Goupiaceae, Desfontainiaceae, Plocospermataceae, Dialypetalanthaceae ("Dialypetalanthus"), Nolanaceae ("Nolana"), Calyceraceae, Heliconiaceae, Cannaceae, Thurniaceae and Cyclanthaceae.
