The ability to sense infrared thermal radiation evolved independently in three different groups of snakes, consisting of the families of Boidae (boas), Pythonidae (pythons), and the subfamily Crotalinae (pit vipers). What is commonly called a pit organ allows these animals to essentially "see" [1] radiant heat at wavelengths between 5 and 30 ...
The detection by predators and competing individuals of same species provides a strong evolutionary pressure. When active sensing is used, energy levels detected at the target are greater than those of the returning signal. Prey or predators evolved to eavesdrop on active sensing signals [citation needed]. For example, most flying insect preys ...

A lineatus feeds on aquatic, semi-aquatic and terrestrial insects, often insects that have just touched the surface of the water or have fallen in and are struggling at the surface. [7] [8] Abiotic sources give off capillary waves of frequency 8–14 Hz, while biotic sources give off much higher frequencies, anywhere from 12–45 Hz and above. [9]
This Jennifer Aniston-fave serum stick is the ideal delivery system for softening fine lines, prepping skin for makeup and targeting dry patches (I've tried it — it actually blurred my wrinkles).
