[2014] nataleigh russell (Room 208): Deep sea

Anglerfish • can grow to 10 cm in length • adult male is smaller than the female • adult male attaches to the female • they mate for life • has an appendage that uses bioluminescenceGulper Eel• can grow to 76cm in length • large mouth • stomach can stretch • can eat prey the same size as itSnipe Eel • grows to 140cm • one of the largest deep sea animals • long beak like mouth • mouth has bristles that snags foodLarvacean • smaller than a pencil • builds a transparent slime house • slime house traps detritus • tail pumps water through slime house • builds a new slime house every daySighonophore • many kinds • can grow to 20cm • live in colonies • tenacles are like lures to capture food

decomposersBacteria are the only decomposers that can survive on the sea floor.

plantsNo plants can grow in the deep sea due to no light penetration in these depths.

food chainAnimals on the surface eat smaller animals. The remains drift down and are eaten by smaller fish which are then eaten by larger fish. The remains drift down to feed the animals on the ocean floor or be decomposed by bacteria.

animals of the deep sea

animal adaptations • body color is transparent, black, red or silvery - helps to camouflague and protection • grow and mature very slowly and live very long lives -decades and even centuries -allows time for reproduction • can survive in harsh conditions -very cold water, very little oxygen, pressure- resistant bodies • bioluminescence -attracts prey and mates

human interference • pollution -people dump sewage, chemicals, waste and trash into the ocean -pollution kills and poisons fish and can make us sick • overfishing -fish become endangered and disrupts the food chain • trawling -nets catch and kill everything in its' path instead of just one kind of fish • oil/gas drilling -drilling causes pollution -disrupts the balance in food chains and destroys plantlife and animal habitats

solutions to human interference • keep beaches clean • clean the ocean • enforce pollution, overfishing and trawling laws • increase fines for breaking laws • stop oil and gas drilling

climate • ocean is divided into 5 zones • deep sea starts at 1,000 m deep and has 3 zones -all 3 zones are very dark, very cold and has scarce food 1. Bathypelagic (Bathyl) zone • 1,000-3,000 m, 42 degrees 2. Abyssopelagic (Abyssal) zone • 3,000-6,000 m, 35 degrees, calm water, little oxygen, high salt concentration 3. Hadalpelagic (Hadal) zone • 6,000 m +, 30 degrees, very high pressure, little oxygen
