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.
For instance, in 1960 (when OPEC formed), the Middle East oil reserves were estimated to be 183 Bb (or 60% of the worldâs total) which increased to 343 Bb in 1970 (55%), 362 Bb in 1980 (53%), 661 Bb in 1990 (53%), 697 Bb in 2000 (55%), and 766 Bb in 2010 (47%).urrent estimates place the Middle Eastâs conventional oil at about 800 Bbo, or nearly half of the worldâs proven recoverable crude. What makes the Middle East so unique is the concentration of numerous giant fields in the region.
