Solanderia
Solanderia is a genus of hydrozoans in the family Solanderiidae, which are colonial, predatory invertebrates. They are commonly known as “fire corals” due to their stinging nematocysts that can cause painful reactions in humans. These corals are not true corals, but rather colonial cnidarians, closely related to jellyfish and sea anemones.
Characteristics
Solanderia species are characterized by their branching, tree-like colonies composed of polyps. The polyps are small and have a distinctive, cylindrical shape with a ring of tentacles surrounding their mouths. The colonies are typically brown or reddish-brown in color and have a rough, textured surface.
Environments
Solanderia species are found in tropical and subtropical waters worldwide. They typically inhabit shallow, rocky reefs and lagoons. These corals are generally found in areas with moderate to high water movement, which helps to keep their polyps clear of sediment and debris.
