“Life after menopause is exceptionally rare in animals. It can evolve only in creatures where grannies help younger family members survive. Only human, killer whale, and short-finned pilot whale females routinely live for substantial periods after they stop breeding. Like humans, killer and pilot whales have roughly twenty-five to thirty childbearing years, then can live another thirty or so. And as Ken’s just explained, some live a lot longer. Up to a quarter of the females in a group are postreproductive. These whales are not waiting to die; they are helping their children survive. As human children often benefit from their grandmothers’ attention, killer whale grandmothers boost their grandkids’ survival. A rather bizarre twist of killer whale society is that killer whale mothers remain crucial to the survival of their adult children. When older killer whale females die, their adult children start dying at high rates, especially males. Male killer whales who are under thirty years old when their mothers die suffer a tripling of the annual mortality rate compared to males in their age group whose mothers are still alive. Male killer whales who are more than thirty years old when their mothers die face death rates more than eight times as high as males in their age group whose mothers are still living. Daughters under thirty show no mortality increase after their mothers’ death. But daughters older than thirty when their mothers die have more than two and a half times the death rate of same-age females whose mothers are alive. Males’ handicaps of the extra drag of their huge dorsal and pectoral fins and the extra food required for their immense size (at around 20,000 pounds, males can be one-third more massive than females) seem to make them reliant on their working mothers for food. Females don’t have the males’ impediments, but while raising young, females may rely on food shared by their no-longer-breeding mothers. Adult females share essentially all the fish they catch, and more than half goes to their children. Adult males share their catch only about 15 percent of the time—usually with their mothers. While no one fully understands their strange death pattern following the loss of a mother, extreme parental care is likely at the root. Toothed whales are the world’s champion nursers. Short-finned pilot whales continue to produce milk for up to fifteen years after the birth of their last calf, likely nursing other females’ young. In bottlenose and Atlantic spotted dolphins (further study might reveal others), some females never give birth. Denise Herzing dubbed them “career females,” because their role in society does not include motherhood. They might be infertile. They might be gay. But their contribution is crucial: they do a lot of babysitting. When Herzing entered the ocean with a visiting nine-year-old girl, “White Patches, the eternal babysitter herself, had never seen me babysitting a young human before. Her excitement vocalizations were audible and electric and she continued to swim around us, eyeing the human youngster attached to me.” (Researchers sometimes call babysitters “aunts.” That’s precisely who they often are.)”

The problem with studying the deep ocean is that humans need light to look at things, the depths of the ocean are extremely dark, and what lives there is accustomed to spending most of its time in that darkness. So when we go down there with submersibles and turn on Big Lights to see, we invariably and dramatically alter what's going on, in the same way that it's generally difficult to observe the natural behaviors of terrestrial animals if you whip out a megaphone and shout HEY GUYS WHAT ARE YOU DOING at them first.

A humble snubnose eelpout on its way to the whale fall buffet when some nearby humans give it a quick, unintrusive study:

I put this in the comments but feel it needs a reblog- Check out some of Dr Edith Widder’s work on light in the deep sea! Among other things, she used the bioluminescence of stoplight fish to deduce wavelengths which most deep sea animals can’t perceive and used that to create light filters to be able to film with minimal disturbance! And that’s how we got 25 minutes of giant squid footage!!!!

the replacement of websites with apps sounds so backwards when you actually describe it. like hmm you have to download an entire program onto your device each time you want access to a portal, where it takes up storage indefinitely. somebody should invent an app where you can "browse" any portal just by typing in its address... 🥴

More context:

the first osprey is the father, the one that comes later is the mother.

ospreys are not eagles, they're ospreys

ospreys only eat fish, that's why they don't register this starling as possible food

the starling got home safely

the starling was not trying to eat the eggs, it was mostly curious and you can see it trying to hop under the osprey every time the osprey tries to sit down again--this is because the starling is still a baby and has the instinct to get under an adult for warmth, even though it mostly has its feathers. this scares the osprey because that is a Foreign Creature near its eggs.

at the end of the video you can see the ospreys starting to turn the eggs. birds do this so the yolk and/or embryo don't stick to the shell of the egg, which is bad for the egg's health.

ospreys have eyes adapted to seeing beneath the surface of the water!
