that figure in the low tens of thousands along with the menace of extinction just reminded me of an interesting thing about the demographics of another species of large animals (though not that large)… one that is already extinct: the Tyrannosaurus Rex: Apparently, the standing population of T-Rex during their existence is estimated to have been only in that ballpark, around 20000… and yet the estimation for the total number of T-Rexes to ever have lived is in the billions… just because T-Rexes have existed for such a long period of time. Of course, that was long before humans came along and killed everything Cf: https://news.berkeley.edu/2021/04/15/how-many-t-rexes-were-there-billions/ https://news.berkeley.edu/2021/04/15/how-many-t-rexes-were-t... (edit: replaced "factoid" with "thing" after a dictionary lookup. What I meant was like "fun fact" but without the degree of certainty that I would require to call it a fact… but without implying likely falsehood as "factoid" apparently would)
