Frontiers | A 28-year record of the isotopic niche of baleen whales in the Gulf of St. Lawrence, Canada: a perspective on ecosystem changes and potential for food competition Fin whales (Balaenoptera physalus), humpback whales (Megaptera novaeangliae) and minke whales (Balaenoptera acutorostrata) seasonally coexist in sympatry in ...

Isotopic analysis of #whale skin biopsies shows diet shift; #fin and #minke whale in Gulf of St. Lawrence are eating more pelagic fish (capelin, herring and/or mackerel) and less krill

Study Finds Larger Baleen Whale Mothers Favor Female Calves

Larger baleen whale mothers are more likely to give birth to female calves, a University of Washington study finds, overturning the expected Trivers‑Willard pattern. getnews.me/study-finds-larger-balee... #baleenwhales #sexratio #evolutionarybiology

Krill and microplastics

Whales are ingesting millions of microplastic pieces daily, particularly baleen whales like blue, fin, and humpback whales, which consume them indirectly by eating contaminated krill and small organisms. #WetTribe #TidetotheOcean #WhaleWednesday #BaleenWhales #Microplastics

The future of baleen whales: Recoveries, environmental constraints, and climate change As the great whales recover from commercial whaling, major mortality events may become more frequent.

"Rather than a 'soft landing', some recovered populations have experienced major mortality events. [...]

Their recoveries have coincided with rapidly accelerating facets of climate change, including dramatic shifts in food web dynamics of high-latitude feeding areas."

Some species of baleen whales may avoid attracting killer whales by singing too low to be heard Killer whales are the only natural predator of baleen whales—those that have "baleen" in their mouths to sieve their plankton diet from the water. More solitary than toothed whales, baleen whales face...

Some Baleen Whales Sing at Low Frequency to Avoid Killer Whale Attacks Learn more about how baleen whales split into two groups — fight or flight — and how these groups determine how loud they sing.

🐋The only natural predator of #baleenwhales are #killerwhales. When attacked, some fight back, while others flee. But whales also produce loud underwater songs…what stops killer whales from homing in & attacking?
