I trust all of you did something for your mothers or at least dropped them a line. Today I have an exciting photo line-up from underwater of a company named SIRENAS www.sirenasmd.com recently funded by the Bill Gates foundation collecting deep-sea sponges with a submersible owned by Substation Curacao. So first off, who is SIRENAS you ask??
