Balaenopteridae – Rorquals
The family of majestic giants of the ocean, the largest animals to have ever lived
Members of this family are named after the longitudinal skin grooves that run from their lower jaws to their bellies. These grooves allow throat expansion, together with flexible jaws that open to 90° enabling them to filter feed by taking in massive gulps of water within a few seconds.
Whales compose songs passed down through generations with small changes every season. They are also specific to whale populations; for example, the North Pacific humpback whales sing the same song (per season), which differs from the humpback whales of the North Atlantic.
