description Gray Whale Overview
The gray whale is a large baleen whale known for undertaking one of the longest annual migrations of any mammal, traveling up to 20,000 kilometers between Arctic feeding grounds and warm-water breeding lagoons in Mexico. Unlike other baleen whales, it is primarily a bottom-feeder, filtering small crustaceans and amphipods from the sea floor sediment through its short baleen plates. The eastern North Pacific population has made a significant recovery since the end of commercial whaling and is currently listed as least concern. They are frequently spotted by observers along the North American coastline.

help Gray Whale FAQ
How far do gray whales migrate?
The gray whale is known for undertaking one of the longest annual migrations of any mammal on Earth. They travel up to 20,000 kilometers round-trip between their Arctic feeding grounds and warm-water breeding lagoons in Baja California, Mexico.
How do gray whales feed differently from other baleen whales?
Unlike other baleen whales that swim with their mouths open to filter the water, the gray whale is primarily a bottom-feeder. It rolls onto its side and sucks up sediment from the ocean floor, using its baleen to filter out tiny crustaceans called amphipods.
Where do gray whales give birth?
Gray whales travel to the shallow, warm-water breeding lagoons along the Pacific coast of Baja California, Mexico, to give birth. These protected nursery areas allow the calves to build up blubber before making the treacherous journey back to the freezing Arctic waters.
Are gray whales friendly to humans?
Gray whales in the Baja California lagoons are famous for actively approaching tourist boats and allowing humans to pet them. This remarkably friendly behavior earned them the nickname "friendly whales" (though whalers historically called them "devil fish").
