Summaries of all of the latest science on blue whales. 'Antarctic blue whale' rearranged is 'Let Branch wail at cue'. Posts by Prof @TrevorABranch.bsky.social
Radically different sternum shapes in adult blue whales (bottom right) compare to juveniles and other whale species. The sternum bone is where all the muscles attach that allow lunge feeding, and determines the kind of filter feeding for each species doi.org/10.1007/s109...
Compilation of 60 satellite tags on blue whales around Australia/Indonesia reveals migration pathways and occasional vagrant wanderers Source: www.nespmarinecoastal.edu.au/publication/...
Automated machine learning tool WHALESHAPE used to find body length and shape for ~1000 whales including ~100 blue whales. Body length estimates within 5% of manual measures for 96% of blue whale images doi.org/10.1111/mms....
Differences between arch calls and D calls in blue whales in the Northwest Atlantic (Gulf of St. Lawrence). Trained detector is able to distinguish between them, finding that arch calls are longer (6.5 sec vs. 1.8 sec) Source: doi.org/10.1109/CAOS...
How do blue whales search for and locate feeding opportunities in their vast, fluid 3D foraging habitat? Check out our new paper, led by John Ryan, which provides a high-resolution answer to this question using a remarkable confluence of bio-logging and oceanographic data tinyurl.com/wa4usbpp
High-precision localized feeding by blue whales
Ryan et al. use biologging and satellite remote sensing to show how blue whales (Balaenoptera musculus) can precisely and persistently localize feeding within a favorable foraging habitat by sensing a...

Precise giants: New research reveals how blue whales find food in a vast ocean 🐋 MBARI biological oceanographer John Ryan shares how a team of researchers used bio-logging tags and satellite data to learn how blue whales find dense swarms of krill. Learn more: www.mbari.org/news/precise...
Three new sightings of blue whales in the SE Arabian Sea, far offshore from India (225-1240 km from Kerala) in ocean depths of 2600-4500 m, all adults. From Indian surveys searching over 280 hr and 5900 km of trackline. doi.org/10.6024/jmba...
Surge in blue whale sightings off Namibia and South Africa suggests they are making a comeback after many thousands were caught on these coasts from 1910s to 1964. Presence of a high proportion of mother-calf pairs (3 of 14 sightings) suggests a calving/nursing region doi.org/10.2989/1814...
Two blue whales were able to precisely target krill aggregations for feeding by following thermal fronts: places with sharp temperature changes in the ocean Ryan et al. (2026) doi.org/10.1016/j.cu...
Blue whale calls detected in the mid-Atlantic Ocean on an extensive seismic network showing that peak calling is in December and centered around the Azores. Surprisingly many calls around Madeira Island given the rarity of sightings there. Figure S4 in Saoulis et al. (2026) doi.org/10.26443/sei...

Blue Whales Shouldn't Be Able to Hunt The Way They Do. Scientists Have Finally Discovered How They Pull It Off
When a blue whale dives below the waves, their heart rate plummets to conserve oxygen.

New assay developed that can detect blue whale DNA in a sample of seawater... though field testing off Newfoundland did not obtain detectable DNA. Fin whales were more detectable this way than visually, though. doi.org/10.1002/edn3... Object Identifier (DOI)

Blue whale calls off Nova Scotia: the two types of calls (infrasonic songs and audible D-calls) are often heard on different days, thus both are needed to detect blue whale presence in the region. doi.org/10.3354/esr0...
New data from Comoros shows blue whale calls there from the SW Indian Ocean blue whale population, but in less than 2% of the dataset, and primarily (75%) in June (data May-Sept). doi.org/10.1111/mms....
More than a thousand blue whale heart beats measured from new tags with ECGs: heart rate at around 5-8 beats per minute rises to ~22 bpm immediately after a feeding lunge, and then slowly declines while filtering out the krill doi.org/10.1073/pnas...
Brilliant work by Rose Hilmo shows individual blue whale tracks in *winter* on feeding grounds in the NE Pacific, demonstrating some that are transiting and others hanging out doi.org/10.3389/fmar...

New sightings and a stranding of blue whales in the SE Atlantic suggest a recovering, but still rare, population www.tandfonline.com/doi/abs/10.2...
In Lamakera, Indonesia (where baleen whaling still occurs), a community survey revealed that 55% see blue whales often. Blue whales are reported caught in in 2021 (baby) and 2022 (adult)*, but should not be. bioflux.com.ro/docs/2026.71... *it is possible these were Omura's or Bryde's whales.

Pretty cool project: Open Tree of Life. Here are the baleen whales in all their glory, with the surprising side story that blue and fin whales, which hybridize frequently, are not very closely related (B. musculus and B. physalus in the figure)
I've released my experimental Open Tree of Life browser at iphylo.org/ott-viewer. You can navigate the Open Tree of Life synthesis tree in all its (complicated) glory. Single click on a node for information, double click to focus on that node, search for node by name.
Test of the effect of marine vibrators on blue whale behavior reveals some avoidance in lower prey densities but no change when prey density is high. doi.org/10.1007/978-...
Major effort to uncover blue whale movements using a catalog of 1074 individually photographed whales in the SE Pacific shows no matches between Chile and the Costa Rica Dome, but matches to the Galapagos. doi.org/10.1111/mms....
