From elephants to bats , kangaroo to sea Lion , mammals are a diverse class of fauna . But what binds them all together is theirability to bring forth Milk River , which female person of the species can use to nurse their young . Unsurprisingly , celebrate this conduct in ocean - dwelling mammal is a lot tough than of those on realm . However , researchers from the University of Hawai’i at M?noa’sMarine Mammal Research Program(MMRP ) have been able to capture some incredible footage ofhumpback whalesnursing their calfskin .
Every wintertime , around 10,000 humpbacksmake the 4,800 - km ( 3,000 - mi ) journey from their rich feeding grounds in Alaska to the warm and relatively protected water in Hawaii for breeding . In purchase order to well document the species ’ behavior at this fourth dimension , theMMRP teamed upwith the Goldbogen Lab at Stanford University ’s Hopkins Marine Station and the Friedlander Lab at the University of California , Santa Cruz , to track calves in the beginning this year .

Off the glide of Hawaii in the Maui bringing up ground , they deploy non - invasive suction cup give chase onto seven humpback hulk calfskin . With acoustical recorders , depth sensors , and accelerometer , the tags supply lucrative data for the team on the movement and breathing patterns of the tag whales . But perhaps the most exciting part was the build - in tv camera .
bring home the bacon investigator with a whale’s - eye view , the “ hulk - cams ” captured moments when sister whale recover Milk River from theirmother ’s feeding glands , whilst Pisces gathered around to slurp up the offshoots . Although the footage only covered between 5 and 20 hours of data per humpback calf , the untested will continue to breastfeed for most of the first year of their life . Broadly speaking , these video will help the team to quantify the nursing behavior of crookback heavyweight ( i.e. breast feeding turn frequency and durations ) .
“ We can actually see what these animals are take care and encountering and experiencing themselves , ” MMRP Director Lars Bejder say in astatement . “ It ’s quite unique and rare footage that we ’re obtaining , which is allowing us to quantify these nursing and suck bouts that are so important . ”
As well as deploying whale - cams , the squad used drones to get together more data on the duration , consistency condition , and wellness of the kyphosis calfskin , which when in full grow can weigh up to 36 measured oodles and measure between 14.6 and 19.1 meters ( 48 to 62.5 human foot ) .
Bejder and his team are no strangers to capturing rare and endearing hunchback whale videos . During last class ’s facts of life season , theyfilmed a newbornonly minutes after it enter the world . Up in Southeast Alaska , during the feeding season , they also recorded dry land - breaking footage of humpback whale hulk during what is known asbubble - net profit eating .
As crookback whales do n’t feed whilst breeding , they swear on energy stores gained from the feeding season . Not only does a goodly supply matter for the mothers , but the calves also need her shop to survive andbecome strong enoughto migrate back up to their summer foraging ground . Therefore , the interplay between these two facet of the MMRP ’s enquiry will provide a rounded insight into humpback whale breeding .
“ Combining these data sets across the foraging and the breeding grounds is really going to tell us something about the grandness of these dissimilar home ground for these beast , ” Bejdersaid .
