Young's modulus, the Young modulus or the modulus of elasticity in tension, is a mechanical property that measures the tensile stiffness of a solid material. It quantifies the relationship between tensile stress and axial strain in the linear elastic region of a material and is determined using the formula:
An elastic modulus is a quantity that measures an object or substance's resistance to being deformed elastically when a stress is applied to it. The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: A stiffer material will have a higher elastic modulus. An elastic modulus has the form:
In materials science, shear modulus or modulus of rigidity, denoted by G, or sometimes S or μ, is a measure of the elastic shear stiffness of a material and is defined as the ratio of shear stress to the shear strain:
Diaptomus is a genus of copepods with a single eye spot. It is superficially similar in size and appearance to Cyclops. However it has characteristically very long first antennae that exceed the body length. In addition, the females carry the eggs in a single sac rather than the twin sacs seen in Cyclops. It is a copepod of larger freshwater ponds, lakes and still waters.

Rissoa guernei is a species of minute sea snail, a marine gastropod mollusc or micromollusk in the family Rissoidae.

Krachia is a genus of minute sea snails, marine gastropod molluscs in the family Cerithiopsidae.
Krachia guernei is a species of sea snail, a gastropod in the family Cerithiopsidae, which is known from European waters. It was described by Dautzenberg and Fischer H., in 1896.
Cerithiella is a genus of minute sea snails, marine gastropod molluscs in the family Newtoniellidae.
Sclerasterias is a genus of starfish in the family Asteriidae. Adult individuals have five arms but small, immature individuals have six. This led to the giving of a separate generic name to the juveniles, Hydrasterias, before it was realised that only one genus was involved. These young individuals often undergo fissiparity. The disc splits into two parts, each bearing three arms, and new arms develop on each part to complete the complement of arms. This sometimes happens repeatedly and may be an adaptation to life in cold, deep seas where most of the species are found.
Photostomias is a genus of barbeled dragonfishes.
Cylindriscala is a genus of predatory sea snails, marine prosobranch gastropod mollusks in the family Epitoniidae, commonly known as wentletraps.
