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.
Others, like me, import rocks into yards that are flat and rockless; we need stronger backs, but the effort is well worth it. Another consideration that can influence the design of rock gardens is space. I am allotting but a small space for my rock garden.In larger spaces, the goal is often to create sprawling, naturalistic rock gardens. But given my space restrictions, I'm contenting myself with what amounts to a round raised bed made of select rocks. This design fits neatly into the nook I have chosen for it. am allotting but a small space for my rock garden. In larger spaces, the goal is often to create sprawling, naturalistic rock gardens.
