Photo taken by China's remote operated vehicle (ROV) Discovery shows a sponge on the Caroline Seamount in the western Pacific Ocean, Aug. 14, 2017. The sponge, with a white reticulate body and crystal thorns, is known as Venus' flower basket. In traditional Asian cultures, Venus' flower baskets were given as wedding gifts because the sponge symbiotically houses two small shrimps, a male and a female, who live out their lives inside the sponge.(Xinhua/Xu Kuidong)
