Model (art)
An art model is a model who poses for any visual artist as part of the creative process. The most common types of art works which use models are figure drawing, figure painting, sculpture and photography, but almost any medium may be used.
Art models are often paid professionals who pose or provide the human figure in a work of art. Though professional, art models are usually anonymous and unacknowledged subjects of the work. Models are most frequently employed for art classes or by informal groups of experienced artists that gather to share the expense of a model. Models are also employed privately by professional artists. Although commercial motives dominate over aesthetics in illustration, its artwork commonly employs models. For example, Norman Rockwell used his friends and neighbors as models for both his commercial and fine art work. An individual who is having their own portrait painted or sculpted is usually called a "sitter" rather than a model, since they are paying to have the work done rather than being paid to pose.
Mimicry
In evolutionary biology, mimicry is a similarity of one species to another that protects one or both. In the case of prey species, it is a class of antipredator adaptation. This similarity can be in appearance, behaviour, sound or scent. Mimics occur in the same areas as their models.
Mimicry occurs when a group of organisms, the mimics, evolve to share perceived characteristics with another group, the models. The evolution is driven by the selective action of a signal-receiver or dupe. Birds, for example, use sight to identify palatable insects (the mimics), whilst avoiding the noxious models.
The model is usually another species, except in cases of automimicry. The deceived signal-receiver is typically another organism, such as the common predator of two species. As an interaction, mimicry is in most cases advantageous to the mimic and harmful to the receiver, but may increase, reduce or have no effect on the fitness of the model depending on the situation. The model may be hard to identify: for example, eye spots may not resemble any specific organism's eyes, and camouflage often cannot be attributed to a particular model.

Offshore (hydrocarbons)
"Offshore", when used relative to hydrocarbons, refers to an oil, natural gas or condensate field that is under the sea, or to activities or operations carried out in relation to such a field. There are various types of platform used in the development of offshore oil and gas fields, and subsea facilities.
Offshore exploration is performed with floating drilling units.
