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.
The rule of thumb for the practical side of designing your own landscape is to group plants with similar requirements together. This includes sun and watering requirements.Grouping them together will reduce maintenance for you (saving you from dragging the garden hose around unnecessarily, etc.).here are, of course, aesthetic considerations (please consult landscape design for beginners), one of the most basic of which is that, in planting bedding plants, you'll produce a greater effect if you mass like plants together (rather than installing one here, one there).
