Flowing water Moving water picks up sediment and carries it downstream. Sediment transport: new landforms. Movement renders oxigen-rich water. Mosses, ﬁshes: salmon, trout. Eroding effect: mountains, deep canyons.
Coastal wetland Regions along the seacost periodically covered by salt water. Mangrove swamps, Salt marshes.Fishes, crabs, shrimps, mudskippers, amphibians, toads, birds, insects.Woody shrubs, trees, vines, mosses.
La Tobara Coastal wetland San Blas, Nayarit. near puerto vallarta.
Marine Zones - Overall 70 % of the earth’s surface. Biotic factors change abruptly through depth. Salinity and temperature vary from place to place. VERY diverse (”Rainforest” of water biomes)Coastal zones: 10% of the marine biome, contain 90% of marine life.
Intertidal (Beach)Large variations in salinity.Litoral.Large variations in temperature.Uneven ﬂow, tides.Crabs, sponges, starﬁsh, tidepool1.jpgsea cucumber, anemones,coraline algae, snails.
Neritic ZoneLying over the continental “shelf”.Bays.Rich in mineral nutrients from land.Proliferation of Phytoplankton andalgae.Oysters, coral animals, algae,dinoﬂagellates.
Oceanic (epipelagic) zone “Open ocean”. Poor in mineral nutrients from land. Less organisms than neritic. Sharks, mackerels, tuna, seals, jellyﬁsh, sea lions, sea turtles, sting rays.
Photic zoneEnough light for phytoplankton,plants.Includes epipelagic and neriticzones.Depth: up to -200m.More: Grunts, ﬁshes, squids.
Aphotic zoneNo sunlight for phytoplankton, plants.Complete darkness.No plants or algae.More: octopus, deep-sea ﬁshes,hatchet ﬁsh, viper ﬁsh, deep-seasquids, nautilus.Bioluminiscent, large eyes, stalking.
Benthic zone Bottom-dwelling organisms. Neritic is also part of the benthic zone. Sea stars, Shrimps, sea crabs, clam oysters, urchins, worms, sponges, anemones. Abyssal zone (deeeeeeeep): Leas organisms.
