Spiracles form a part of the abdomen region of the grasshopper. They consist of tiny holes that permit air to enter trachea. Spiracles lie along the sides of the abdomen and the thorax. Tubes stem out from the spiracles and carry air to all parts of the body for respiration. The trachea is the respiratory surface of the grasshopper. Since water travels easily along this surface, it is prone to water loss. The respiratory surface is protected thanks to spiracles.
Grasshoppers have two thoracic and eight abdominal spiracles. These insects have valves that allow them to close their spiracles, thus reducing water loss. Spiracles are known to possess intricate opening and closing mechanisms that are physiologically helpful to regulate air flow and lessen water loss from the insect
because the insects forgot to drink water

Cactus are able to conserve water due to their stems. They have stems that are able to store water for when it is needed.
i no it starts w/ a c! cuticle - Patel
many plants developed a wazy surface cuticle to reduce water loss
The waxy coat helps to reduce water loss from the leaves.
The scales on the fish body helps it to reduce water loss.

Cactus have a waxy layer on them to prevent water loss and reduce transpiration

The wax surface is there to reduce water loss from the stem and leaves, and also helps protect or reduce insect attack.
Reduce loss of water through transpiration / evaporation.
Introduce baffles which inhibit the movement of air/water/whatever
Mutual fund do not reduce the risk of loss.
