I have not read or heard anything saying you cant. I have seen people carry them in their lap though.
Where as there might not be regulations regarding domestic flights, there are restrictions regarding travelling to foreign countries.
Simple diseases like various fungi or insects, parasitic or not, are not supposed to cross borders. This in particular important when one fly from one place to another where these organizms normally would not be able to go without help.
There are warnings about this on airports and ferry places in Norway, Denmark, Sweeden, although some people do not heed the warnings and think that it does not matter.
Plants that may seem fine can be a jungle of various organizms too small for the human eye to notice. For these to cross borders can in worst case scenario become a big problem.
Where as you in most cases can actually get away with doing it, I would strongly advice against it due to the risk of contamination of destination.

Some things you should never pack in your checked luggage are money, jewelry, credit and debit cards, and travelers checks. You should also not pack prescription medication in your checked luggage.

You can pack them in your checked luggage, but you cannot bring them with you on the plane, such as in pockets, purse, carry-on bag, etc.
Just do not pack foods that need refrigerating unless you freeze it and pack it safely but airport security will still check this. Also do not pack items that smell.
It is not a good idea. Moose are very large animals and being packed in a checked bag would be dangerous for you, the animals, and all the baggage handlers.
