Why is "Pliny on mammals" trending?

Wikipedia Overview

Book VIII of Pliny the Elder's Natural History centres around the concept of zoology, and mainly that which pertains to terrestrial animals, including mammals, amphibians, reptiles, as well as some birds and insects. Pliny discusses these animals as being a part of specific categories, firstly starting with those he considers to be wild, including, but not limited to, elephants, snakes, lions, giraffes, rhinoceroses, lynxes, camels, leopards, hyenas, foxes, rabbits, skinks, beavers, frogs, seals, geckoes, chameleons, deer, reindeer, jackals, porcupines, bears, hedgehogs, squirrels, snails, crocodiles, and lizards. He then goes on to cover those he considers to be domesticated, such as dogs, horses, donkeys, mules, oxen, sheep, goats, and pigs. Following this, he mentions animals that are “half-wild," or what he considers to be wild varieties of commonly domesticated animals, including boars, chamoises, ibexes, oryxes, antelopes, monkeys, and hares, as well as those that are “neither wild nor tame but of a character intermediate between each," such as swallows, bees, dolphins, and mice. Lastly, on various occasions he mentions animals that would be considered mythological, such as unicorns, pegasi, basilisks, and werewolves, of which he considers only the existence of werewolves to be obviously improbable.
