Humpback whales have clever techniques to hunt their food, like jumping to catch food or using one of their strategies called Bubble-net feeding. Humpback whales primarily feed by a method called “lunge feeding“. They locate their prey, often small fish or krill, by using a variety of hunting techniques, such as bubble net feeding. Then, they accelerate towards the target with their mouths wide open, flooding large amounts of water and prey. They use their baleen plates, which are comb-like structures in their mouths, to filter out the water while trapping the food, allowing them to swallow their meal.
What do Humpback whales eat?
Humpback whales are omnivores so their diet consists of animals and plants. They need to consume a lot of food each day as part of their extensive diet. Their diet includes:
- Sea snails
These are the very basic food that they eat in the ocean. They whales will eat between 3,000 to 5,000 pounds of food each day.
What do baby Humpback whales eat?
During the first year of Baby Humpback whales, they are nursed and fed milk from their mother. This milk helps them grow rapidly during the critical early period of life. As they mature, they transition to eating krill, small fish, etc. This diet change prepares them for adulthood when they become skilled filter-feeders, consuming large quantities of these tiny creatures to sustain their impressive size and energy needs.

How do Humpback whales hunt?
How do Humpback whales find and eat enough krill and other small fish to make that possible? It’s a fair question, and it becomes even more interesting when you add in the fact that these whales are hard to miss from a prey’s point of view. They use a feeding technique called “bubble-net feeding.” A group of whales work together to create a circular bubble net around a school of fish, then swim upwards while vocalizing, which drives the fish towards the surface. The whales lunge through the concentrated prey with open mouths, catching large amounts of fish in one gulp. This cooperative strategy helps them feed efficiently.
What eats Humpback whales?
Humpback whales are large marine animals not typically preyed upon by other species. Their main predators historically were killer whales (orcas), especially targeting calves. However, adult humpback whales are generally too large and powerful to be quickly taken down by predators. The biggest threat to them is human activities, such as ship strikes and entanglement in fishing gear.

How do Humpback whales adapt to different seasons?
Humpback whales adapt to different seasons in several ways. During the feeding season in colder months, they migrate to polar waters where food is abundant, and they build up fat reserves. In warmer months, they move to warmer waters for breeding and calving, conserving energy and avoiding harsh conditions. They completely depend on their migration and behavior on the food and the need to reproduce, allowing them to thrive in changing environments throughout the year.
Are Humpback whales dangerous to humans?
Humpback whales are generally not considered dangerous to humans. They are known for their gentle nature and are unlikely to pose a threat to people. However, as with any large wild animal, it’s essential to maintain a safe distance and respect their space when observing them in the wild. Accidental collisions or other rare incidents can occur, but deliberate aggression from them toward humans is extremely rare.
