Introductionrom the Greek νηκτηρ, i.e. swimming. As Haeckel defined it, nekton describes collectively all swimming animals that are ‘free to choose their path’, i.e. can resist a strong current of water and, distinct from planktonic animals, go where they wish.

Maintaining the Body Suspended In the Waterater. This capacity is ensured first of all hydrostatically, by approximation of the animal’s mean density to that of the water, either fresh or salt, in which it dwells. The animal’s buoyancy Δ, which is the difference between the density ρ., of the water and its own mean density ρ (Aleyev 1963a,b)

Reducing Resistance to Movementfe and constitutes one of the most general specific features of nektonic animals, since the total hydrodynamic resistance encountered by a nektonic animal determines the overall expenditure of energy required by the given ecology. The task of reducing the hydrodynamic resistance encountered by the a

Controlling Movementegative accelerations, i.e. speeding up and braking. The performance of all these functions is connected with the creation of moments ., rotating the body of the nektonic animal about axes passing through its centre of gravity. For a moment . to arise it is necessary to apply a single force or a pai
