The platypus (Ornithorhynchus anatinus), sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its family Ornithorhynchidae and genus Ornithorhynchus , though a number of related species appear ...
Among the monotremes, the platypus (Ornithorhynchus anatinus) has the most acute electric sense. [37] [38] The platypus localises its prey using almost 40,000 electroreceptors arranged in front-to-back stripes along the bill. [34] The arrangement is highly directional, being most sensitive off to the sides and below.
Billed snouts on the duck-billed dinosaurs hadrosaurs are strikingly convergent with ducks and the duck-billed platypus. [76] Ichthyosaurs (such as Ophthalmosaurus) [77] are marine reptile of the Mesozoic era which looked strikingly like dolphins. [78] Several groups of marine reptiles evolved hyperphalangy similar to modern whales. [61]

This group is known as the duck-billed dinosaurs for the flat duck-bill appearance of the bones in their snouts. The ornithopod family, which includes genera such as Edmontosaurus and Parasaurolophus , was a common group of herbivores during the Late Cretaceous Period . [ 1 ]
The platypus is one of the few living mammals to produce venom. The venom is made in venom glands that are connected to hollow spurs on their hind legs; it is primarily made during the mating season. [1] While the venom's effects are described as extremely painful, it is not lethal to humans.
