Scientists transplanted 42 sea sponges into a polluted Spanish marina; 91.7% of one species survived

Scientists transplanted 42 sea sponges into Marina Palamós, a polluted Spanish marina.

% of the chicken kidney sponge (Chondrosia reniformis) survived for 455 days.

The surviving chicken kidney sponges began creating mobile clones.

The study in Frontiers in Marine Science suggests these filter feeders could help clean polluted harbors.
