The Green star polyp is a hardy colonial invertebrate commonly kept in aquariums. Its characteristic bright green star-shaped polyps seem to glow in the sunlight. These tiny filter feeders can absorb organics from the water column, and like other corals, the polyps of this species also house zooxanthellae, photosynthetic algae cells which provide the coral with nutrients. A purple mat of tissue, known as a stolon, connects the multiple polyps, often covering the rock beneath it.
With 27 species, the Euphonias comprise another very large genus of Tropical American Birds. They are found from the Mexican State of Sonora, down to Argentina and Bolivia, as well as a number of Caribbean islands. The DWA has exhibited several species. Long considered tanagers, they have been recently reclassified as finches. This species, found over a large area of eastern South America, has been a popular bird in private collections and zoos since the Victorian era. It has bred at the DWA.
Specializing in crayfish, crabs, and other crustaceans, this small heron has gourmet tastes. Once considered a rather tropical bird, it has expanded its North American range in recent years to the north and west. It is also found throughout Central and South America. It has nested repeatedly in this exhibit, performing courtship displays and raising chicks.
