UK trade in ivory from hippos, narwhals, orcas and sperm whales has been banned as part of conservation efforts, the Government has said. The Ivory Act, introduced to protect elephants, has been extended to ban the importing, exporting and dealing in items containing ivory from the four species, the Environment Department (Defra) said. People breaking the rules by trading in ivory – found in teeth and tusks - from the species could face an unlimited fine or up to five years in jail.
