The Blue Whale is a marine mammal belonging to the suborder of baleen whales (called Mysticeti). At 30 metres (98ft) in length and 180 metric tons (200 short tons) or more in weight, it is the largest known animal to have ever existed.
Long and slender, the blue whale's body can be various shades of bluish-grey dorsally and somewhat lighter underneath.
Blue Whale as with other baleen whales, diet consists almost exclusively of small crustaceans known as krill. The species of this zooplankton eaten by blue whales varies from ocean to ocean. An adult blue whale can eat up to 40 million krill in a day. The whales always feed in the areas with the highest concentration of krill, sometimes eating up to 3,600 kilograms (7,900 lb) of krill in a single day.
There are several different species of whales you are likely to encounter on one of our trips. California Gray Whales, Humpback Whales, Blue Whales, Finback Whales and Orca Whales (Killer Whales) are common sightings in the waters surrounding the Loreto National Marine Park Islands. Additional wildlife includes sea lions, dolphins and a rich variety of bird life; some of which are endangered and protected.
Loreto offers magnificent opportunities to view Great Whales. Loreto is a world-class blue whale observation destination.
