Duck-Billed Platypus: Ornithorhynchidae
Platypus are considered "common but vulnerable" by the government of Australia. It is plentiful in some areas, but is considered vulnerable due to habitat destruction from dams, irrigation projects, being caught in fish nets and lines, and water pollution.
Platypus are strictly protected by law and harsh penalties in Australia, which is agreeable with most, if not all, Australians, since the animals are not pests and are now national emblems. The Australian government and private groups like the Australian Platypus Conservancy keep close eyes on platypus populations and have proposed relocating some of the urban platypus to suitable natural areas where they have been driven from by development in the past.
