Mysidacea
monsoon seasonal variation of the weather in the tropical Indian Ocean. Because of the heating during the summer of the Asiatic land mass to the north
there is a variation in the pressure distribution that causes more or less a
reversal of the normal trade wind pattern (~climate). As a consequence, during the (northern) summer westerly winds prevail north of the equator, and
in response the circulation pattern in the ocean shows marked seasonal
variations.
morphology the study of form, e.g., of organisms, the sea floor, coastal forms,
land forms (geomorphology).
mortality (syn. death rate) the number of individuals of a population dying in a
given period, ~population parameters. In fishery research, natural mortality
(death caused by natural factors such as predation) is distinguished from
fishery mortality (caused by catches by man).
mother of pearl ~nacreous layer.
MPC maximum permissible concentration, ~maximum allowable concentration.
MSY ~maximum sustainable yield.
mucoid feeder mechanisms mechanisms of collecting food by means of a structure made of mucus produced by the animal itself.
mucous glands generally unicellular glands which secrete mucin, a protein polysaccharide, which, with water, forms a lubricating solution called mucus.
mud slimy and sticky mixture of water and fine-grained particles with a consistency varying from that of a semifluid to that of a soft plastic sediment.
Muds are generally described by color, e.g., black mud, gray mud, red mud.
mud flat ~tidal flat.
mudflow sediment-gravity flow in which more than 50 % of the solid fraction consists of particles smaller than 64 Ilm.
multi-net ~nets.
mutualism ~symbiosis.
Mysidacea (opposum shrimps, mysids) order within the Peracarida (class Malacostraca, subphylum Crustacea, phylum Arthropoda). Small, pelagic shrimp-like crustaceans of which the majority lives in the sea or in a brackish environment,
