After 2009, the severe drought conditions continued to get worse and occurred throughout the central Texas region, where the Houston toad population resides. It was calculated that during peak breeding season in March 2011, central Texas received under .10 inches (2.5 mm) of rain making it the fourth driest March since 1856.
The Guadalupe bass (Micropterus treculii) is a rare species of fish endemic to the U.S. state of Texas, [2] where it also is the official state fish.It is restricted to creeks and rivers (including the Guadalupe River, hence the name Guadalupe bass), and is listed as near threatened. [1]
Populations of large predatory fish in the global oceans were estimated to be about 10% of their pre-industrial levels by 2003, [1] and they are most at risk of extinction; there was a disproportionate level of large predatory fish extinctions during the Cretaceous–Paleogene extinction event 66 million years ago.

A chameleon successfully capturing prey with its tongue. In ecology, hunting success is the proportion of hunts initiated by a predatory organism that end in success. Hunting success is determined by a number of factors such as the features of the predator, timing, different age classes, conditions for hunting, experience, and physical capabilities.
A stoat surplus killing chipmunks (Ernest Thompson Seton, 1909) Multiple sheep killed by a cougar. Surplus killing, also known as excessive killing, henhouse syndrome, [1] [2] or overkill, [3] is a common behavior exhibited by predators, in which they kill more prey than they can immediately eat and then they either cache or abandon the remainder.
The two authors produced broadly similar range estimates. They found that before deforestation and hunting began to shrink its range, the ivory-billed woodpecker had ranged from eastern Texas to North Carolina and from southern Illinois to Florida and Cuba, [29] typically from the coast inland to where the elevation is approximately 30 m (98 ft ...
A cheetah exhibiting pursuit predation. Pursuit predation is a form of predation in which predators actively give chase to their prey, either solitarily or as a group.It is an alternate predation strategy to ambush predation — pursuit predators rely on superior speed, endurance and/or teamwork to seize the prey, while ambush predators use concealment, luring, exploiting of surroundings and ...
Topographic map of Texas. This is a list of mammals of Texas. Mammals native to or immediately off the coast of the U.S. state of Texas are listed first. Introduced mammals, whether intentional or unintentional, are listed separately. The varying geography of Texas, the second largest state, provides a large variety of habitats for mammals.
