Hemprich’s cauliflower coral
Dendronephthya hemprich
Special Features
Dendronephthya hemprich is a colorful, non-branched soft coral with bright red, pink, or purple trunks and white, feathery polyps.
Unlike stony corals, it does not have a hard skeleton but a flexible protein and strap-like structure. Therefore, it sways like a little underwater tree with every current.
Appearance
It grows straight up like a little tree and forms striking contrasts with the surrounding reef rock, often the first thing that catches the eye. The polyps are often slightly open at night to catch food particles from the water, allowing the coral to remain active even in the dark.
Natural Enemies
Some snails and fish that specifically eat soft coral tissue.
Despite their bright colors, these corals have very few natural enemies, as the tissue is inedible or difficult to digest for many species.
Dangerous/Toxic
Not toxic, but very sensitive; even slight contact can damage the tissue.

Pro Tips
They are best seen in strong side currents. Stay still in position and take the opportunity for close-ups. Soft corals like D. hemprich are streamlined, so keep an eye on the current: It will show you exactly from which direction the water brings food. Especially at dusk, it's worth taking a look at the hunting activities of small reef fish nearby.
