Balaenid whales feed on large aggregates of small and slow-moving prey (predominantly copepods) through a filtration process enabled by baleen. These whales exhibit continuous filtration, namely, with the mouth kept partially opened and the baleen exposed to oncoming prey-laden waters while fluking. The process is an example of crossflow filtration (CFF) in which most of the particulates (prey) are separated from the substrate (water) without ever coming into contact with the filtering surface… 

Oral cavity flow distribution and pressure drop in balaenid whales feeding: a theoretical analysis

A theoretical model coupled with oral cavity velocity and pressure in balaenid whales is established based on mass conservation, momentum conservation and pressure drop equations, considering both the inertial and the friction terms, and provides a reference for the design of high-efficiency bionic filters.

Theoretical analysis of the hydrodynamic filtering system in the balaenid whales suspension feeding

A theoretical model is established to analyze the hydrodynamic filtering system in the balaenid whales suspension feeding and shows that the particle trajectories consist of a series of backward-outward arcs and the food particles tend to accumulate in the posterior region of the oral cavity.

How do baleen whales stow their filter? A comparative biomechanical analysis of baleen bending

The baleen of right and bowhead whales is longer than the height of the mouth; experiments show it is highly flexible and bends along its length to accommodate mouth closure, which has major consequences not only for feeding morphology and energetics but also for conservation.

In vivo intraoral waterflow quantification reveals hidden mechanisms of suction feeding in fish

A new technique to quantify three-dimensional patterns of intra-oral water flows in vivo and shows, for carp and tilapia, that water tracers displayed higher curvatures than food tracers, indicating an inertia-driven filtration, providing a complete picture of the suction-feeding process.

Why whales are big but not bigger: Physiological drivers and ecological limits in the age of ocean giants

Gigantism in whales is both driven and limited by prey capture and availability, and filter feeding provides an evolutionary pathway to extremes in body size that is not available to lineages that must feed on one prey at a time.

Lunge Feeding in Rorqual Whales.

The biomechanics of the lunge feeding mechanism in rorqual whales that underlies their extraordinary foraging performance and gigantic body size are reviewed.

Foraging energetics and prey density requirements of western North Atlantic blue whales in the Estuary and Gulf of St. Lawrence, Canada

The results underscore the necessity for blue whales to seek the highest densities within patches to reach neutral balance or allow energy storage, and may help predict the effects of climate and natural variability or of potential fisheries on krill densities and blue whale condition.

Bio-inspired Filter Design Based on Vortex Control Mechanism of Parallel Groove Structure

Solid–liquid separation is widely used in daily life and practical engineering. Traditional industrial filters are prone to clogging, but this rarely occurs in filter-feeding organisms. Inspired by

Comparative Three‐Dimensional Morphology of Baleen: Cross‐Sectional Profiles and Volume Measurements Using CT Images

Within a baleen specimen, the intra‐baleen void volume correlates with the average bristle diameter for a species, suggesting that essentially, thinner plates (with more space between them for flow) have thinner bristles.



Baleen Hydrodynamics and Morphology of Cross-Flow Filtration in Balaenid Whale Suspension Feeding

Preliminary investigation of baleen from balaenopterid whales that use intermittent filter feeding suggests that although the biomechanics and hydrodynamics of oral flow differ, cross-flow filtration may occur to some degree in all mysticetes.

Hydrodynamic and Sensory Factors Governing Response of Copepods to Simulated Predation by Balaenid Whales

Results support previous research showing hydrodynamic effects within a whale’s oral cavity create slight suction pressures to draw in prey or at least preclude formation of an anterior compressive bow wave that could scatter or alert prey to the presence of the approaching whale.

Results indicate that unique features of balaenid oral construction and function not only permit steady, unidirectional flow of water through the mouth, but also establish Bernoulli and Venturi effects during feeding.

Behaviour and kinematics of continuous ram filtration in bowhead whales (Balaena mysticetus)

It is concluded that a food niche of dense, slow-moving zooplankton prey has led balaenids to evolve locomotor and filtering systems adapted to work against a high drag at swimming speeds of less than 0.07 body length s−1 using a continuous fluking gait very different from that of nekton-feeding, aquatic predators.


The shape of the baleen rack in the bowhead appears to be an adaptation to reduce the amplitude of the bow wave projected during feeding, the simultaneous advantage being concentration of prey slurries inside the mouth.

Drag from fishing gear entangling North Atlantic right whales

Lethal and sublethal fishing gear entanglement is pervasive in North Atlantic right whales (Eubalaena glacialis). Entanglement can lead to direct injury and is likely to incur substantial energetic

Summertime foraging ecology of North Atlantic right whales

North Atlantic right whales were instrumented with suction-cup mounted, time-depth recorders (TDR) during the summers of 2000 and 2001 to examine their diving and foraging behav- ior. Simultaneous

The filter pads and filtration mechanisms of the devil rays: Variation at macro and microscopic scales

It is proposed that species with cilia on the rakers augment the shear mediated movement of particles along the filter with ciliary transport, and mobulids can use cross‐flow filtration in which this shearing force serves as a mechanism to resuspend food particles initially caught by sieving or another capture mode.

The results indicate that the kinematics of the propulsive flukes and hydrodynamics are associated with the swimming behaviors and morphological designs exhibited by the whales in this study, although additional factors will influence morphology.

Metabolic Expenditures of Lunge Feeding Rorquals Across Scale: Implications for the Evolution of Filter Feeding and the Limits to Maximum Body Size

The results not only point to a physiological limit on maximum body size in this lineage, but also have major implications for the ontogeny of extant rorquals as well as the evolutionary pathways used by ancestral toothed whales to transition from hunting individual prey items to filter feeding on prey aggregations.
