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.
Sand slopes can be landscaped with a mixture of perennials, groundcovers, bushes and trees, with a layer of shredded bark. (On the surface, NOT tilled in.) Different root depths using little water will tie up the slope, the mulch will stop most surface activity.he planting needs to be a mix of groundcovers, shrubs, trees, and perennials with the areas between plants(if there are any openings) covered with appropriate mulch and/or boulders. A varied planting is FAR more effective than a monoculture on a slope.
