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.

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.
