Most of the time, the collective noun for a group of animals is fairly mundane and not specialized to the animal, at least in the scientific literature.
Most pack hunters form packs. Most herd animals form herds. Most birds, and the occasional sheep, form flocks. Most fish form schools. Most whales and dolphins form pods. Most (non-human) primates form troops. Most insects form swarms.
All of these terms, along with family, litter, nest, hive and colony - for more specialized groups of animals - have scientific merit.
Meanwhile, the more fanciful, specialized "terms of venery", like murder of crows, gaggle of geese, business of ferrets, et cetera, are rarely if ever used in a scientific context. With one exception.
Lions are pack hunters. But a "pack" of lions is universally known as a pride of lions, even in the scientific literature. Why was this one species singled out for its term of venery?
It's not like a murmuration, a particularly large flock - originally and most commonly of starlings - whose emergent behavior is mesmerizing and of scientific interest in its own right. A pride of lions is just a bunch of lions that live and hunt together, no different from a pack of wolves (except for the fact that lions are felines and wolves are canines).
Why are lions, and lions alone, preferentially collected by their specialized term of venery, even in the scientific literature?
a shrewdness of apes/monkeys a bellowing of bullfinches ...
