In the past few weeks, Blue Whales have been regularly spotted of the coast of San Diego. Soon, Hornblower Cruises & Events will offer Whale Watching cruises that head out to sea in search of Blues and other baleen whales. Our summer whale watching cruises begin June 29 and run from Fridays to Mondays through the end of summer.
Why are Blue Whales so exciting to watch? These giants are the largest animals on Earth, reaching lengths of 100 feet (about 2/3 of the length of the Adventure Hornblower) and weighing up to 150 tons (slightly less than the weight of the average American house). The Blue Whale’s blow/spout can be 30 feet tall, letting our captains and naturalists spot them from far away. When a Blue Whale surfaces, you typically see the spout first, then the head, then the bluish-gray body, then the tiny dorsal fin, and finally, if you are lucky, the tail flukes lifted above the surface.
What brings Blues to local waters? In summer, the nutrient-rich,coastal waters of Southern California often provide tons and tons of krill. And the abundance of shrimp-like krill, are magnets for hungry whales in search of food. Like Gray Whales and other baleen whales, the Blue Whale has brush-like baleen in its mouth that it uses to strain krill and other tiny clustered prey out from the water. An adult blue whale can consume up to 4 tons of krill per day!
