The pair was skim feeding — which is a feeding method in which the whale opens its mouth, allowing small prey to swim through its baleen. The mom and calf were skim feeding.
Bubble-net feeding is a feeding behavior engaged in by humpback whales [1] and Bryde's whales. [2] It is one of the few surface feeding behaviors that humpback whales are known to engage in. [ 3 ] This type of feeding can be done alone or in groups with as many as twenty whales participating at once. [ 4 ]
The skim-feeders are right whales, gray whales, pygmy right whales, and sei whales (which also lunge feed). To feed, skim-feeders swim with an open mouth, filling it with water and prey. Prey must occur in sufficient numbers to trigger the whale's interest, be within a certain size range so that the baleen plates can filter it, and be slow ...
Some are dragged behind the boat, following the path of a whale that was skim feeding. A vertical tow is lowered into the water to determine how deep in the water column the food source is.
Lunge feeding is more energy-intensive than skim-feeding due to the acceleration and deceleration required. [64]: 367–386 The skim-feeders are right whales, grey whales, pygmy right whales, and sei whales (which also lunge feed). To feed, skim-feeders swim with an open mouth, filling it with water and prey.
Gray whales are typically observed alone or in small groups, though large groups may be seen at feeding or breeding grounds. Bird and her team conducted their research off Newport. On sailing ...
The hypothesis that W. rewhenua was a skim feeder suggests that skim filter-feeding may have been the earliest form of feeding in the edentulous Chaeomysticeti clade. [ 1 ] Based on the enlarged temporal fossae and enlarged mandibular canal, Waharoa was probably incapable of lunge-feeding, although it remains unclear whether it could skim-feed ...
Three North Atlantic right whales -- Spoon, Tux and a whale listed in the North Atlantic Right Whale Catalog as #3550 -- on Feb. 20 were spotted echelon feeding in the Great South Channel, an area ...
