860-287238 - Platypus or Duck-billed platypus, Ornithorhynchus anatinus, eating a Australian freshwater crayfish, Cherax quadricarinatus. They also eat worms, insect larvae, freshwater shrimps that it digs out of the riverbed with its snout or catches while swimming. It uses cheek-pouches to carry prey to the surface, where it is eaten. The platypus needs to eat about 20% of its own weight each day, which requires it to spend an average of 12 hours daily looking for food. They have a sense of electroreception locating their prey in part by detecting electric fields generated by muscular contractions. Queensland, Australia - Composite image
860-287264 - Aerial view of Basking shark, Cetorhinus maximus, and kayak. is the second-largest living shark, after the whale shark, and one of three plankton-eating shark species, along with the whale shark. Adults typically reach 6?8 m (20?26 ft) in length. The gill rakers, dark and bristle-like, are used to catch plankton as water filters through the mouth and over the gills. Despite their large size and threatening appearance, basking sharks are not aggressive and are harmless to humans. The basking shark has long been a commercially important fish, as a source of food, shark fin, animal feed, and shark liver oil. Overexploitation has reduced its populations to the point where some have disappeared and others need protection England

Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth to live young.
