Visible light spans from about 760 to 380 nanometers in wavelength, which is the same as about 430 terahertz to about 750 terahertz. The low-frequency end corresponds to light that we perceive as the color red. The high-frequency end is related to light that we see as violet.
Jaguars vary quite widely in weight. The normal range might be 56-96 kilograms (124-211 pounds). Big males can weigh 159 kilograms (350 pounds), and the smaller cats can weigh as little as 36 kilograms (80 pounds). Males are typically 10 to 20 percent larger than the females. A link to the Wikipedia article on the jaguar is provided.
They weigh anywhere from 65 to 200 pounds (29 to 91 kg) and range in length from three to seven feet (0.9 to 2.1 m), not including tails, which are about two to three feet (0.6 to 0.9 m) long. The average adult black leopard stands two feet high at the shoulder. A female black leopard is usually about a half to two-thirds the size of its male counterpart. An average jaguar's size is usually bigger than that of a leopard. Black jaguars stand about 27 to 30 inches (68 to 76 cm) high at the shoulders. Male jaguars weigh from 125 to 220 pounds (57 to 100 kg) and range about 5.6 to 7.9 feet (1.7 to 2.4 m) long from nose to tail. Female jaguars weigh from 80 to 170 pounds (36 to 77 kg) and range about 5 to 7 feet (1.5 to 2.1 m) long from nose to tail. Their tails are less than one-third of their body length.
