The newly discovered 'ninja' slug, Ibycus rachelae, uses 'love darts' made of calcium carbonate to pierce and inject a hormone into a mate to increase the chances of reproduction, in an unknown location in the "Heart of Borneo", in a remote area of dense, tropical rainforest that borders Malaysia, Indonesia and Brunei.
A flame-colored snake, Dendrelaphis kopsteini, is seen in this photo. Discovered in 2007, the snake differs from its closest relatives by a bright orange pattern behind its head. When threatened, the snake can flare its nape, revealing bright orange colors.
