26. The Harp Sponge (Chondrocladia lyra)
Described in 2012, the Harp Sponge astonished scientists with its beautifully branching, harp-like structure. This unusual form is not just decorative—it is highly specialized for snaring small crustaceans carried by deep-sea currents. Sticky filaments along its “strings” capture prey, making the harp sponge one of the deep’s most fascinating carnivorous sponges. To explore more about this remarkable organism, visit MBARI.
