Mangroves and sea urchins. Black sea urchins (class Echinoidea) in front of mangrove trees growing on the coast, showing the exposed roots. These upright spikes are called pneumatophores and are the breathing tubes for the tree's submerged roots. Photographed on Bunaken Island, Sulawesi, Indonesia. | |
