It's not because he's a human, it's because he feel that knowing about who he have to deal with in a daily basis is worth the investment.
That way of thinking would work with literally any student of the animal school.
Lanka knowing about every peculiarity of her "pack members" would make sense as she deal with different animals on a daily basis, so that extra knowledge can prove to be useful in case something exclusive to a certain animal happens.
Does it apply if it's something exclusive to humans? Yes.
Does it apply if it's something exclusive to wolfs? Yes, but she's already one so it isn't strange for her to know about her own specie.
Does she feel like she needs to know about her "pack members" species peculiarity? No.
Does He feel like he needs to know about every animal's peculiarity in the school? Yes, because as it has been proved, he does deal with different animal problems that are (mostly) exclusive to their species.
It's not about if it's a real necessity, it's about if he feel like it's worth the investment or not.
For most of the academy, it isn't, but for him it is worth and have been proved worth before.
Just see how many times he knowing about something "exclusive" to a certain specie solved problems no one else was being capable of.
It just paid back enough times to justify the investment.
