Blue whale behavior?

Blue Whales feed almost exclusively on krill, though they also take small numbers of copepods.[24] The species of this zooplankton eaten by Blue Whales varies from ocean to ocean. The whales always feed in the areas with the highest concentration of krill, sometimes eating up to 3,600 kg (8,000 lb) of krill in a single day.[24] This means that they typically feed at depths of more than 100 m (330 ft) during the day, and only surface feed at night. Dive times are typically 10 minutes when feeding, though dives of up to 20 minutes are common. The longest recorded dive is 36 minutes (Sears 1998). The whale feeds by lunging forward at groups of krill, taking the animals and a large quantity of water into its mouth. The water is then squeezed out through the baleen plates by pressure from the ventral pouch and tongue. Once the mouth is clear of water, the remaining krill, unable to pass through the plates, are swallowed. The Blue Whale also incidentally consumes small fish, crustaceans and squid caught up with krill Source: Wikipedia

How long was the blue whale extinct?

Blue Whale populations have declined significantly due to extensive and uncontrolled hunting. Blue whale hunting was banned in 1966 by the International Whaling Commission. But, by 1970 330,000 blue whales had been caught & killed in the Antarctic, 33,000 in the rest of the Southern Hemisphere, 8,200 in the North Pacific, and 7,000 in the North Atlantic. The largest original population, in the Antarctic, had been reduced to 0.15% its original count.

Now that the hunting of these giant animals is banned, their numbers has started to increase and I don't think they will go extinct.
