Evolutionary Tendencies Parasitic Copepods of Fish by Kazachenko VN in Modern Approaches in Oceanography and Petrochemical Sciences (MAOPS)- Lupine Publishers
Parasitic copepods inhabit invertebrates and vertebrate’s animals. They have changed under the influence of parasitic life.
Changes affected the body form, the reduction of segments and limbs. They have neoplasms (horns, tree-like processes, bullae,
suckers, lamellar lobes, etc.).Parasitic copepods have subdued huge number of species
hosts among invertebrates (coelenterates, annelids, crustaceans,
mollusks, echinoderms etc.) vertebrates (fish, amphibians,
mammals). Parasitic copepods have mastered sea and fresh water,
but most species live in marine environment. The abundance
of marine host species allowed them to implement expansion,
because in the marine environment, they found greater number
of environmental niches. Among copepods there is wide range of
forms, standing at different stages of adaptation to parasitic life.
Here we see copepods little changed in parasitic life.
