Blue Whales

Blue Whales



The magnificent Blue Whale is the largest animal ever known to have lived on our planet. This mammal is so gargantuan in fact, that their hearts weigh as much as a car and their tongues weigh as much as an elephant. Even at birth, it is one of the world’s largest animals! Fully grown Blue Whales weigh up to 441,000 lbs or 200 tons. They’re gigantic, they’re enormous, they’re ginormous! Generally ranging in length from 80 to 100 feet (24 to 30 meters), the biggest one ever recorded was a staggering 108 feet long or almost 33 meters! Imagine a typical tractor trailer driving down the highway at 100 feet long.

Not only are these guys and gals the largest known animals, they’re also the loudest! Consider that a jet engine registers at 140 decibels.The call of a Blue reaches 188 decibels, which means these behemoths can hear each other over 1,000 miles away!

What’s equally impressive is that these Blues feed only on krill which are less than an inch long. They consume approximately 9,000 lbs of these little guys a day.  The Monterey Bay offers whales a high abundance of krill, which means that we are a hot spot for Blue Whale activity every year!  Where these whales congregate to mate and give birth remains unclear but is suspected to take place somewhere off the southern coast of Mexico.

The Blue Whale population you’ll witness on your excursion with Sea Spirit is one of the largest and healthiest in the world. These gentle giants thrive along our coastline.
