When seen from below by a predator, the animal's light helps to match its brightness and colour to the sea surface above. Counter-illumination is a method of active camouflage seen in marine animals such as firefly squid and midshipman fish, and in military prototypes, producing light to match their backgrounds. Marine animals of the mesopelagic (mid-water) zone tend to appear dark against the bright water surface when seen from below.
A landscape is usually made up of a hardscape and a softscape which means the trees, plants and grass. The use of boulders, tiles, sculptures, walkways or bird baths can be used to create a beautiful sitting area, a place for entertaining guests, or an outdoor cooking space.
Xeriscape means that there is some water in well-controlled amounts of water and locations in the landscape. Xeriscape is NOT lawnless landscape. Some lawn, even species that are highly watered can be wise water usage.
