Occurrence of microplastics in the gastrointestinal tract ... Out of the 504 fish examined, 184 had items that were identified as synthetic polymers (36.5%). None of the pieces matched spectra obtained from nitrile gloves used in dissections, nets used in the standard hauls or bags used to store fish prior to examination. Fish - Wikipedia Fish are gill-bearing aquatic craniate animals that lack limbs with digits.They form a sister group to the tunicates, together forming the olfactores.Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. Demersal fish - Wikipedia Demersal fish can be divided into two main types: strictly benthic fish which can rest on the sea floor, and benthopelagic fish which can float in the water column just above the sea floor.. Benthopelagic fish have neutral buoyancy, so they can float at depth without much effort, while strictly benthic fish are denser, with negative buoyancy so they can lie on the bottom without any effort.
