Summary Humpback whales (Megaptera novaeangliae) employ a unique and complex foraging behaviour — bubble-netting — that involves expelling air underwater to form a vertical cylinder-ring of bubbles around prey. We used digital suction cup tags (DTAGs) that concurrently measure pitch, roll, heading, depth and sound (96 kHz sampling rate), to provide the first depiction of the underwater behaviours in which humpback whales engage during bubble-net feeding. Body mechanics and swim paths were…

Pectoral herding: an innovative tactic for humpback whale foraging

Three ways in which humpback whales use pectorals to herd prey are found: create a physical barrier to prevent evasion, cause water motion to guide prey towards the mouth, and position the ventral side to reflect light and alter prey movement.

Simulation of humpback whale bubble-net feeding models.

A fully-coupled phase-averaging approach is used to model the flow, bubble dynamics, and corresponding acoustics of humpback whales' bubble nets, finding higher void fraction nets appear preferable, guiding even low-frequency vocalizations while still maintaining a quiet net interior.

Evidence for acoustic communication among bottom foraging humpback whales

This study investigates the role of a novel broadband patterned pulsed sound produced by humpback whales engaged in bottom-feeding behaviours, referred to here as a ‘paired burst' sound and provides important evidence for the use of acoustic signals among foraging individuals in this species.

Body density of humpback whales (Megaptera novaengliae) in feeding aggregations estimated from hydrodynamic gliding performance

The results show that tissue density of shallow diving baleen whales can be estimated using the hydrodynamic gliding model, although cross-validation with other techniques is an essential next step.

How Baleen Whales Feed: The Biomechanics of Engulfment and Filtration.

The current state of the field is reviewed by exploring several hypotheses that aim to explain how baleen whales feed, including multi-sensor tags, active acoustic prey mapping, and hydrodynamic modeling.

Bottom side‐roll feeding by humpback whales (Megaptera novaeangliae) in the southern Gulf of Maine, U.S.A

Humpback whales (Megaptera novaeangliae) are known for the variety and complexity of their feeding behaviors. Here we report on the use of synchronous motion and acoustic recording tags (DTAGs) to

Surface feeding behavior of humpback whales in the Magellan Strait

Each feeding behavior tended to be consistent in regards to the prey species available at a given time, however, the data set did not contain a sufficient sample size to fully interpret this association with the available prey species.

Potential energy gain by whales outside of the Antarctic: prey preferences and consumption rates of migrating humpback whales (Megaptera novaeangliae)

The observed lunge rates when feeding on krill, to the best of the authors' knowledge, are higher than any previously reported rates of whales feeding, and suggest that whales may begin to restock energy supplies prior to reaching the Antarctic.



Diel changes in humpback whale Megaptera novaeangliae feeding behavior in response to sand lance Ammodytes spp. behavior and distribution

The data provide novel insights into the behavioral ecology of humpback whales and their prey, indicating significant diel patterns in for- aging behaviors concurrent with changes in prey behavior.


Several feeding be­ haviors reported for the first time, as well as a number of behaviors known from other areas but not previously reported for these waters, provide the beginning of a more complete catalog than has previously been available.

Underwater Tracking of Humpback Whales (Megaptera Novaeangliae) With High-Frequency Pingers and Acoustic Recording Tags

A long-baseline (LBL) acoustic system has been developed for the tracking of humpback whales (Megaptera novaeangliae) that have been tagged with digital acoustic recording devices (DTAGs), providing

Kinematics of foraging dives and lunge-feeding in fin whales

Examination of body kinematics at depth reveals variable lunge-feeding behavior in the context of distinct kinematic modes, which exhibit temporal coordination of rotational torques with translational accelerations.

The behavior of Pacific herring schools in response to artificial humpback whale bubbles

These experiments suggest that herring have a strong fear of bubbles and can readily be manipulated or contained within bubble nets by predators.

Fine-scale prey aggregations and foraging ecology of humpback whales Megaptera novaeangliae

It is found that: (1) time of day was the most important factor in predicting whether a whale was feeding when it surfaced; and (2) surface feeding occurred more often around more dense, vertically distributed schools of prey.

Hydrodynamic design of the humpback whale flipper

The morphology and placement of leading edge tubercles suggest that they function as enhanced lift devices to control flow over the flipper and maintain lift at high angles of attack in the humpback whale.

Leading-edge tubercles delay stall on humpback whale (Megaptera novaeangliae) flippers

The humpback whale (Megaptera novaeangliae) is exceptional among the baleen whales in its ability to undertake acrobatic underwater maneuvers to catch prey. In order to execute these banking and

Morphological specializations of baleen whales associated with hydrodynamic performance and ecological niche

Feeding behavior, prey type, and habitat appear to be associated with the morphological design of body, fluke, and flippers in baleen whales, and these lent themselves to the following classifications based on hydrodynamic principles: fast cruiser, slow cruiser, fast maneuverer, and slow maneuververer.
