I believe I take longer to comment on organisms with longer descriptions, and when more than three organisms are submitted per day.
"prey--bugs"
That should be an emdash, although it's only a minor quibble.
"speaking of", is a rather colloquial and incorrect phrasing. I recommend either using "speaking of which" or, better yet, omitting it entirely.
"off of" is redundant. It seems to be a collouqial error, in the manner of "try and do" rather than "try to do". "Off" is sufficient.
"their walking position" Are you talking about the finger, the organism, or the organism population as a whole?
Consider:
"A lion uses its claws to attack prey."
"Lions use their claws to attack prey."
"The lion uses its claws to attack prey."
"A lion's claws are sharp. If not filed down, their points curl like hooks." (Understood to mean "the nails' points", not "the lion's points", though both are actually correct.)
Does it not chop down obsidoaks because it recognizes it's far more than it needs, or because too many Twigfisher Shrogs got their tails stuck in a tree or died? Or do Twigfisher Shrogs get their tails stuck in trees sporadically, and either tell others about it, or are observed by others?
The third explanation is the most plausible. Elephants can learn that herder humans are harmless, while hunters are dangerous, and crows apparently can tell other crows about humans who mistreated them.
I wouldn't call the blond one "blond". I'd use "beige". Admittdly, its paler parts are sort of blond, but the champagne one is named after its main color, not its paler color.
