The Texas Longhorn is a breed of cattle known for its characteristic horns, which can extend to 7 ft (2.1 m) tip to tip for steers and exceptional cows, and 36 to 80 in (0.91 to 2.03 m) tip to tip for bulls.

Texas Longhorns are known for their diverse coloring. A longhorn can be any color or mix of colors but dark red and white color mixes are the most dominant. Texas Longhorns with elite genetics can often fetch $40,000 or more at auction with the record of $170,000 in recent history for a cow (Mar 18, 2017 new record: $380,000).

The pig keeps company with the cows.

The mesquite tree is an extremely hardy, drought-tolerant plant because it can draw water from the water table through its long taproot. It can also easily and rapidly switch to use water in the upper part of the ground. Many consider the tree a nuisance because it competes with rangeland grasses for moisture. In parts of Texas, the proliferation of mesquite is blamed for lowering groundwater tables.

The bean pods of the mesquite can be dried and ground into flour. Mesquite bean flour can be used in breads, pancakes, muffins, cakes and cookies. Cattle eat the beans when other food supplies are low. The beans can help sustain animals in times of drought. The beans are high in carbohydrates and are an energy source, but should not be eaten in excessive amounts.

One of the most wide-spread mammals in the Western Hemisphere, the Mexican free-tailed bat ranges from the southern half of the continental United States through most of Mexico, and through most of Central America into South America. The largest known colony is found at Bracken Cave, north of San Antonio, Texas, with nearly 20 million bats. In Austin, Texas, a colony of (approximately 1.5 million) Mexican free-tailed bats spends summer under the Congress Avenue bridge, ten blocks south of the Texas State Capitol.

Mexican free-tailed bats are primarily nocturnal insectivores and hunt using echolocation. Traveling calls are of a brief but constant frequency. However, they switch modulated frequency calls between 40 and 75 kHz if they detect something. Typically, the frequency range of their echolocation is between 49 and 70 kHz, but can be between 25 and 40 kHz if something crosses their path while in flight

The striped bark scorpion is a common scorpion found throughout the midsection of the United States and northern Mexico. Although the sting is painful, it is rarely deadly.

The Black Widow

The female black widow is a highly venomous species of spider with distinct red and black coloring that will occasionally eat her mate after reproduction. She is shiny and black in color, with a red marking in the shape of an hourglass on the underside of her abdomen. Black widow venom is an extremely potent neurotoxin. Neurotoxin activity can be characterized by the ability to inhibit communication between neurons across a synapse.

The black and yellow garden spider builds zigzag webs and is considered harmless to humans.

The brown donkey disappeared for a few days. She was discovered in a thicket with her new baby.

The 9N, produced by Ford, introduced the first three-point hitch system on American-made tractors, a design which is still utilized on most modern tractors today. The first Ford tractor was the 9N, the first tractor to have both three-point hitch and a rear Power Take Off. The 9N was fitted with the Ferguson system three-point hitch, a three-speed transmission, and featured footpegs instead of running boards. Uniquely, the exhaust was routed underneath the tractor, much like an automobile. Though this one has been painted red and white, all 9N tractors were originally painted dark grey.

The eye of the snail

Logarithmic spirals (growth spirals) are very common in the natural world. The golden spiral is a logarithmic spiral that has a growth factor of the golden ratio (1.6180339..). Snails, plants, and the arms of spiral galaxies can have the shape of a logarithmic spiral.

The female black widow protects an egg sac containing hundreds of eggs.
