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.
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.

[73] Seahorses and allies (Syngnathiformes) The largest of this diverse order is the red cornetfish (Fistularia petimba), a long, thin species found in all tropical oceans.

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.
Loss of habitat could largely remove some of the most important predators — and some of the most commercially important seafood species — from the Climate change takes habitat from big fish ...

They are unique among electric fish in not possessing electroreceptors, meaning that they do not use an electric sense to locate prey. [2] Stargazer's paired electric organs are aligned vertically inside the head, behind the eyes. [3] Uniquely, they are used only for hunting or defence, as the fish does not electrolocate. [2]
