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:
Sonny Bono Salton Sea National Wildlife Refuge
Visibility varies greatly from species to species due to the nocturnal habits of some and seasonal hibernation of others. Most rodent species exist in terrestrial habitats where they provide important food resources for raptors and other predators. During winter months, rodents provide food for heron and egret species as well. Muskrats are present in freshwater drains and ponds where their feeding and burrowing activities help maintain marsh habitats for various other wildlife species.Due to environmental factors, amphibians are not found in large numbers or diversity at the Sonny Bono Salton Sea NWR. Species occurring on the refuge include bullfrogs and lowland leopard frogs. Lowland leopard frogs respond well to shallow, permanent wetland habitat created for the Yuma clapper rail. They are not present elsewhere on the Refuge due to competition from exotic bullfrogs. Woodhouse's toad and red-spotted toads are also found on the refuge.
