How Baleen Whales Feed by Sean Chamberlin

The baleen whales generally feed in three different ways that affect the type of prey they consume. Some baleen whales, like the right and bowhead whales, feed by skimming at or near the surface. Swimming slowly with their mouths open, their dense baleen plates—up to 350 in a right whale—strain the water for krill, macrozooplankton (copepods) and fishes too small to avoid capture. The whale expels the captured water and licks the concentrated prey off their baleen using their tongue.

Rorquals employ a feeding style called gulping. This feeding method involves the containment of huge quantities of water—up to 70 tons in the blue whale—that is subsequently strained through their baleen. By expanding their throat grooves, the rorquals can inflate their mouths to four times their normal circumference. The engulfed water is pressed against the roof of their mouths with their tongue and squeezed between the baleen as their throat pouch contracts. The captured food is removed with their tongue. The jaws and tongues of rorquals exhibit specialized muscles and processes for engulfment feeding (see Lambertson et al., 1995). A number of unique behaviors are associated with engulfment feeding. Fin whales (Balaenoptera physalus) use vibrations of their jaw to produce sound to startle and concentrate their food. Humpback whales (Megaptera novaeanglia) work in concert with one another to catch herring use a style of feeding called bubble-netting or bubble-cloud feeding. In bubble netting, most often observed in North Pacific populations (Clapham, WhaleNet web site archive, 2000) one individual of the group circles and creates a net of bubbles while the other humpbacks circle and corral the herring. When the herring are concentrated at the surface, the whales lunge through the school and consume their prey. In bubble-cloud feeding, more typical of North Atlantic populations, a burst of bubbles is used to concentrate the herring. Studies have shown that herring avoid bubbles and so would be susceptible to bubble nets or clouds (Sharp and Dill 1997). Nonetheless, crittercam studies, using cameras attached to the whales, reveal that a significant number of herring can escape the bubble net so their feeding is not 100% efficient (National Geographic Crittercam 2004). A number of other cetaceans use bubble net or clouds but few with the degree of sophistication observed in the humpbacks

A variation on bubble-cloud feeding involves a slap of the tail following the initiation of the bubble cloud. This form of feeding, called tail slap or lobtail feeding, was apparently adopted by juvenile humpbacks in response to a shift in prey availability from herring to the smaller herring-like sand lance, who spend part of their time in sand. Prior to 1982, only 12.5% of individuals at Stellwagen Bank (at the mouth of Massachusetts Bay) exhibited lobtail feeding while after 1982 more than 50% of humpbacks were engaged in the behavior. These scientists suggested that adoption of this mode of feeding occurred through cultural transmission, a form of learning among whales (Weinrich et al., 1992) though that interpretation has been disputed (Galef 2001). From 1991-1195, declines in sand lance abundance led to observations of yet another type of feeding behavior, called jaw scuffing or prey flushing. Humpback whales were observed to scrape their jaw on the sandy bottom apparently to startle sand lance and flush them out of hiding (Hain et al., 1995; Stellwagen Bank NMS web site).

Another bottom feeding behavior—the third major type of feeding attributed to baleen whales—is mud scooping. To date, this behavior has been observed only in gray whales (Eschrichtius robustus), the lone member of a family of whales with shorter and less numerous baleen plates (~130-180 per individual) and less prominent throat grooves. The gray whale is well-known along the U.S. west coast for its 10-14,000-mile annual migration from the Bering and Chukchi Seas to Baja California (ACS Online). At the northern end of its distribution during summer months, the gray whale feeds by scooping large mouthfuls of mud from the sea bottom and filtering out benthic amphipods, decapods and other soft-bottom invertebrates. Apparently, the gray whale will make two passes at the sea bottom, the first to suspend the top layer of sediment and the second to filter the resultant suspension. In this way, the whale avoids ingestion of the heavier sediments (e.g. Russell 2001). Gray whales have been observed by scuba divers to vacuum sediments from one side of their mouth while expelling water from the other to strain food. Feeding in the frigid Arctic waters led scientists to wonder about heat loss through the mouths and tongues of baleen whales. Dissections on gray whale carcasses by John Heyning and colleagues at the Natural History Museum of Los Angeles revealed a counter-current exchange system in the tongue of these animals. Because presence of a structure does not ne3cessarily prove its function, these scientists were unable to test their hypothesis further. However, the rescue of the orphan gray whale JJ by the museum staff and housing of the animal at SeaWorld in January 1997 afforded an opportunity to take tongue temperature measurements of a gray whale while feeding. Their studies confirmed that the gray whale tongue loses little heat to the surrounding water during feeding, confirming the role of countercurrent heat exchangers (NHM web site: http://www.nhm.org/research/mammals/jj/index.html).

The foraging activities of gray whales results in a series of shallow feeding pits—up to several feet in diameter—that mark the trail of a feeding gray whale. The overturning of bottom sediments and disturbance of these habitats has a significant impact on benthic community structure in habitats where gray whales feed. Scavenging amphipods increased in abundance 20-30 fold over undisturbed sediments, accumulations of organic debris were greater and opportunistic species were favored. (Oliver and Slattery 1985). Disturbance is likely an important factor in the maintenance of diversity in a variety of benthic habitats (e.g. Dernie et al., 2003). Gray whale feeding has also been hypothesized to have an effect on nutrient recycling. From 9 to 27% of the sea bottom may be processed by gray whales in the northern Bering Sea the result of which may be enhanced decomposition of organic material and regeneration of nutrients (Encyclopedia Marine Mammals 2002).

The feeding behavior of baleen whales and their effects on krill populations in the Southern Ocean have become a topic of considerable discussion. A study by Laws in 1985 suggested that the reduction in baleen whales caused by whaling (estimated at 90% of the original population) led to shifts in the structure of Antarctic food webs by reducing grazing pressure on krill and thereby favoring other krill predators. In a similar vein, the return of baleen whales in modern times has been postulated as the cause of declines in krill abundance, a conclusion used to support a resumption in whaling. As we learned in an earlier chapter, krill populations are subject to a number of ecological factors, including climate-induced variations in sea ice, aggregation behavior and others. Thus, the actual abundance of krill, the role of baleen whales in Antarctic ecosystems and any potential competition with fisheries remain highly uncertain. The interactions between whales and humans continues to be a controversial social and political issue. Inquiring minds are urged to apply scientific understanding wherever possible before accepting facts presented on either side of the debate (see Young 2000).
