It is a predator fish and is capable of swimming at speeds up to 75kmph. It is fished commercially and is also popular as a game fish. In colour, tunas are generally dark above and silvery below, often with an iridescent shine. They have a conspicuous keel on either side of the tail base. Tunas are unique among fishes in their ability to maintain the temperature of their bodies above that of the surrounding water, often between 5 and 12°C above ambient water temperature. Tuna is generally considered to be rich in omega-3 fatty acids. The yellow fin tuna is the variety that is used in the canned form. Their maximum length is around 7.8ft and weight is 440lbs.

Pistachio being a desert plant has tolerance towards saline water and can also survive temperature from -10 degree C to 48 degree Celsius. Another popular name of pistachio is pista. The nut is a rich source of antioxidants and helps lower the cholesterol level. The seed has a mauve skin and light green flesh, with a distinctive and unique flavour. When the fruit ripens, the shell changes from green to an autumnal yellow or red, abruptly splits open. And this opening happens with an audible pop. Each pistachio tree averages around 50kg of seeds every two years. Iran, the United States and Turkey are the major producers of pistachios. The trees are planted in orchards, and take approximately seven to 10 years to reach significant production. When the researchers tested the effects of pistachios on antioxidant levels they found participants had much more antioxidants in their blood and lower cholesterol concentrations when they ate the nuts. The kernels are often eaten whole, either fresh or roasted and salted, and are also used in pistachio ice cream, kulfi (Indian ice cream), gulab jamun filling pistachio butter, pistachio paste and desserts such as baklava, pistachio chocolate, pistachio halva, pistachio biscotti and cold cuts such as mortadella. Americans make pistachio salad, which includes fresh pistachios or pistachio pudding, whipped cream, and canned fruit.
