Whales in the southern oceans have similarly wide-ranging effects.
One of the many post-rational excuses made by the Japanese government for killing whales is that they said, "Well, the number of fish and krill will rise and then there'll be more for people to eat."
Well, it's a stupid excuse, but it sort of kind of makes sense, doesn't it, because you'd think that whales eat huge amounts of fish and krill, so obviously take the whales away, there'll be more fish and krill.
You take the whales away, and the number of krill collapses.
Well, it now turns out that the whales are crucial to sustaining that entire ecosystem, and one of the reasons for this is that they often feed at depth and then they come up to the surface and produce what biologists politely call large fecal plumes, huge explosions of poop right across the surface waters, up in the photic zone, where there's enough light to allow photosynthesis to take place, and those great plumes of fertilizer stimulate the growth of phytoplankton, the plant plankton at the bottom of the food chain, which stimulate the growth of zooplankton, which feed the fish and the krill and all the rest of it.
The other thing that whales do is that, as they're plunging up and down through the water column, they're kicking the phytoplankton back up towards the surface where it can continue to survive and reproduce.

It was instrumental in stopping commercial whaling, and was built on the idea that if we couldn't save whales, what could we save?
Whales in our waters are still low in numbers, however, because they do face a range of other human-induced threats.
This is actually a disservice, because whales are ecosystem engineers.
So let's talk about why saving whales is critical to the resiliency of the oceans.
As whales dive to the depths to feed and come up to the surface to breathe, they actually release these enormous fecal plumes.
So really, having more whales in the oceans pooping is really beneficial to the entire ecosystem.
Whales are also known to undertake some of the longest migrations of all mammals.
