Well that was my understanding
I've been buying hunting and fishing licenses for many
years, and have never heard anything of a separate
license for hunting exotic or non game

If it's in the book I missed it
If I'm invited to hunt at a place with exotics with
full permission to take anything, someone was
saying that I'll need a license to cover that.
( not a TPWD employee)
I was under the impression that a valid resident
hunting pretty much covered whatever except for
what the tags and stamps are required for

Never heard of an exotic license, resident or otherwise

Is this a bunch of hooey ?

Requirements and Exceptions
In addition to a hunting license, additional endorsements may be required.

For specific information on Lifetime, Disabled Veteran, Texas resident active duty military, and Combination licenses, view combination hunting and fishing licenses packages.

Information about public hunting opportunities is available, including an interactive map of over 1 million acres of accessible lands.

All laws and regulations governing hunter education requirements still apply.

A hunting license is required of any person (resident or nonresident), of any age, to hunt any animal, bird, frog or turtle in this state, except the following:

coyotes, if the coyotes are attacking, about to attack, or have recently attacked livestock, domestic animals, or fowl.
feral hogs on private property with landowner authorization.
fur-bearing animals, if the hunter possesses a commercial trapper’s license.
depredating fur-bearing animals, if a landowner (resident or non-resident) or landowner’s agent is taking fur-bearing animals causing depredation on the landowner’s land. No portion of the nuisance fur-bearer may be possessed, sold or retained for any purpose.
