  4. Spouts
    • Blue Whales: Known for their powerful spouts that can reach up to 6 meters high and be seen from several kilometers away.
    • Humpback Whales: Their spouts are balloon-shaped and reach about 3 meters high.
  5. Behavior and Hunting Techniques
    • Blue Whales: Typically solitary and rely on their large size to consume vast amounts of krill.
    • Humpback Whales: More social and known for their unique bubble net feeding technique, where they create bubbles to trap fish.
  6. Habitat and Migration
    • Blue Whales: Found in open oceans worldwide, except the Arctic, they migrate long distances but prefer deeper waters.
    • Humpback Whales: Often seen near the coast and known for their long migrations, traveling up to 16,000 miles annually between feeding and breeding grounds.
  7. Vocalizations
    • Blue Whales: Emit low-frequency sounds that can travel hundreds of miles underwater.
    • Humpback Whales: Famous for their complex songs that are often heard during the breeding season.

How to Spot Them

When you’re out whale watching, here’s how you can identify these majestic creatures:

  • Blue Whales: Look for their massive size, bluish-gray color, and tall, powerful spout. They have a wide blowhole bump on their head and a tiny dorsal fin.
  • Humpback Whales: Identify them by their medium size, black back, and unique spout shape. They are often seen breaching and slapping their long pectoral fins on the water.

Final Verdict

While Blue Whales and Humpback Whales share some similarities to baleen whales, their differences in size, appearance, behavior, and habitat make each species uniquely fascinating. Whether you’re marveling at the sheer size of a Blue Whale or enjoying the acrobatic displays of a Humpback Whale, these giants of the ocean never fail to inspire awe and wonder.
