SECRET WEAPON
Life is a battle where those better fit and prepared will have a better chance to reproduce and survive. It is an adaptation result of the product of natural selection. Which means that natural selection occurs when individuals vary in their hereditary attributes in ways that affect how many surviving they contribute to the next generation. Therefore, insects develop numerous defense strategies or mechanisms to avoid the capture by predators; such as chemical, camouflage, and an advertisement of unprofitability to deter pursuit. Chemical defense is more popular among insects and typically behave in conspicuous manner, for example, pump beetle's defend themselves by using an acidic and toxic spray.
When the pump beetle is attacked by a frog and there is the reaction chamber that happens when the predator(frog) attacks the pump beetle. And the beetle's use its toxic spray to defend from being captured by the frog. The beetle's have an enzyme that split up the explosion by forming a separate pulse of spray and the louder explosion is in sequence. As soon as the pump beetle's feel the contact with frog, it contracts its abdomen and releases the toxic from the end part of the abdomen in all directions.Pump beetle’s spray is very toxic and hot, when toads attack them its spray causes the toad’s tongue to burn and swell. Therefore, the pain and discomfort caused by the spray causes the frog to run away.
