From The Guardian:
Life in the Wild is an exploration of the extraordinary diversity of the animal kingdom through photographic portraits of mammals, birds, reptiles, fish and invertebrates. It features the work of Thomas Marent, who has devoted his life to capturing the beauty of the natural world, and the acclaimed team of underwater cameramen, Scubazoo, who have filmed for the BBC, National Geographic and Animal Planet
Leafy sea dragon
The leafy sea dragon (Phycoduras eques) is a rare and stunning animal named after the leaf-like projections that cover its body. This remarkable camouflage means it has no natural enemies – except man. It has a long, pipe-like snout for feeding, primarily eating crustaceans, including plankton and mysids. However, although it will also eat shrimp and other small fish, it has no teeth, which is rare among animals with this diet. Leafy seadragons are found only in the waters of Australia from the southern to the western shoreline.
Acrid chemicals in the body of this Peruvian grasshopper (Aplatacris colorata) act as a defence against insect-eating predators. The grasshopper's vivid pattern of warning colours advertises the fact that it has a noxious taste and, since most of its enemies are birds that hunt by sight, the warning is very effective. Any bird that tries to eat one of these grasshoppers is unlikely to make the same mistake twice. The concentrated toxins in the insect's body are made from chemicals in its food plants.
