Baleen whales swim through the water with their mouth open, taking in large volumes of water that contain the tiny ocean creatures. The fringed baleen then acts as a sieve â the whales squeeze the water out through the baleen, leaving their food caught on the baleen. Then they use their tongue to wipe the baleen clean before swallowing their food. In the northeast U.S., the common toothed whales are pilot whales, dolphins, and porpoises. Common baleen whales are humpbacks, minkes, and right whales.
Iran has the largest gas network in the world with 30,000 kilometers of high-pressure pipelines. Iran's proven oil and gas reserves are 137 billion barrels (10% of world's total) and 41.14 trillion cubic meters (15% of world's total) respectively, which give it a unique status in the global energy supply.
Oil production World oil production grew by only 0.4 million b/d in 2016, the slowest growth since 2013 Production in the Middle East rose by 1.7 million b/d, driven by Iran (+700,000 b/d) Iraq (+400,000 b/d) and Saudi Arabia (+400,000 b/d, but this was largely offset by declines in North America, South & Central America, Africa and Asia Pacific.
