; even during the dinosaur era!! Nothing is or has ever been as big as the Giant blue whale getting up to 110 ft long and 400,000 lb. When these big girls give birth to their 23-26 ft long calves they nurse them as much as 50 gallons a day so the calves can gain up to 200 lb. (90 kg) a day!! Before these calves are weaned they have grown two thirds of their adult length of as much as 50 ft long in the first year of life.
The largest population of Blue whales work the waters in Monterey Bay to feast on the abundance of krill and the biggest whales can consume up to 12,000 lb of food a DAY. They are able to fill their mouth and throat grooves with several tons of tasty prey every time they take a gulping lunge. (see picture) To get some perspective and give you a mental picture of their size, the eye ball is the size of a basket ball. Their heart is the size of a V.W. bug automobile and they are equivalent to 30 elephants.
