Red Dead Redemption 2
Rockstar would like to inform you that Red Dead Redemption 2 will have about 200 species of animals, birds, and fish. All of these creatures will "behave and respond to their environment in a unique way."

I am assuming that every single one of these animals will be able to be hunted, killed, and skinned. It just wouldn't feel right if you couldn't do that in a Red Dead Redemption sequel.

Rockstar also passes along word that there are 19 different breeds of horses that you will be able to find in the world. These 19 breeds will have "59 different styles of coat" and you will be able to customize the crap out of them. I am assuming you cannot hunt these, but maybe just maybe.
Deer, bison and pronghorn traverse the plains in large herds, scavengers quickly sniff out carrion, sockeye salmon leap upstream, wolves attack in packs surrounding their prey, geese fly in fixed formations, possums play dead, rodents scamper into tree hollows, grizzly bears bluff charge when threatened, and birds of prey soar on thermals. They all form part of a complex ecosystem and must continually fight for their place on the food chain. The wilderness is at once a bountiful and perilous place, for both man and beast, and any predator can quickly turn prey.

Rockstar kindly also provided some images with captions to help us all to better understand just how we will hunt and skin those animals.

Red Dead Redemption 2
Hunting wildlife provides valuable natural resources like meat, hides and other useful materials. You can sell meat and animal parts to Butchers or General Stores, donate them to your Camp, or use them to cook and craft. For more exotic goods, bring your haul to a Trapper.

Red Dead Redemption 2
Game can be found across a range of habitats. If your first shot is not immediately fatal, your prey will try to escape. Follow clues like blood to track it down and you may need to use a mercy kill to end the animal’s suffering.

Red Dead Redemption 2 hunting
Selecting the proper weapon is important to the quality and yield from your kill. Bow and arrow is often the optimal weapon of choice for clean kills. Approach prey quietly, cover your scent or stay downwind to make it harder for animals to detect your presence, and use a call to draw its attention before making your fatal strike.

Red Dead Redemption 2 fishing
Like hunting, fishing also yields meat and useful materials. A range of species can be found in different habitats, each responding to different varieties of bait.

That's all fine and dandy, but what about horses? How does having 19 different breeds of horses suit you? That's a lot to choose from. And choose you will because each of them will have different characteristics.
There are 19 breeds of horse in Red Dead Redemption 2 from Appaloosas and Arabians to Shires to Mustangs, each of which handles differently with its own defined characteristics. Horses can be captured and broken out in the wild, purchased from stables or acquired by more underhanded means, of course.

Your horse is your constant companion, and you will rely on them just as heavily as on any of your fellow gang members so it is important to take good care of your animal. By keeping it groomed and well-fed, you will start to see improvements in stamina, performance and handling and it will become less skittish as the bond grows between you. With 59 different styles of coat, and a huge range of customizable tack, including saddles, horns, stirrups, spurs, you can create a horse that is truly your own, and develop a personal and unique relationship as you explore the world together.

Wild Hungarian Half-Breeds can be found in the Heartlands among other habitats. Capturing and taming wild horses can be a free method to acquire new mounts.
