My brother is into entomology. Do you know much about it?
1_Wizard
I know that it is the study of insects, which is a branch of zoology.  Did he go to college for it, or is it just a pasttime for him?
0_Apprentice
It is just a pastime for him, but he also has considered taking classes for it so he can go into it professionally. 
1_Wizard
There are 1.3 million species of insects, so there is a lot for him to study if he chooses to.

I had no idea there were so many

And it also overlaps with a lot of other topics like genetics, biochemistry, ecology, biology, and even paleontology - he may need a graduate degree to be able to work in this field.

Oh wow. I am going to let him know, I don't think he knows it will take so much work. Plus I don't want it to take the fun out of it for him.

Yes, even just modern biology is an incredibly vast field - my daughter wants to be a vet and it's astronomical how many classes it involves.

I've always wanted to be a vet as well but I know it takes much work. I love animals a lot.

Yes, she's looking at 8 full years of school plus state board licensing exams.
