In the winter, the Karankawa moved inland to hunt deer, bison, and other animals. They also gathered nuts, berries, and other plants.
In the spring, the Karankawa returned to the coast to fish and gather shellfish. They also planted crops such as corn, squash, and beans.
In the summer, the Karankawa continued to fish and gather shellfish. They also traded with other Native American groups for goods such as pottery and weapons.
In the fall, the Karankawa prepared for the winter by hunting and gathering food. They also built shelters to protect themselves from the cold weather.
By adapting their way of life to the changing seasons, the Karankawa were able to survive in a harsh environment.
