Marine Habitat Micro-Education Series
In the subtidal to infralittoral zones where the tides ebb and flow, we can find hydroids with well-developed branching structures on rocky walls, filtering plankton as the current passes through. Because their structure resembles that of gorgonians / sea fans in octocorals, they are often mistaken for them. On closer inspection, the hydroid polyps can be identified by their white, club-shaped form — quite different from the flower-like coral polyps of sea fans. Hydroids are home to many resident creatures, some with such excellent camouflage that they are very difficult to spot, putting everyone's observational skills to the test! Let's get to know them together through the Marine Habitat & Marine Life Micro-Education Series!
