The Ocean Habitat and Evolution of Animals: Adapting to the Largest Habitat on Earth

Discover the ocean habitat, which comprises up to 97% of all livable space on Earth. Explore the unique life forms and how animals have evolved to fit in this vast environment. Learn about the different zones and the adaptations animals have developed to thrive in each. From the coastal neritic zone to the open pelagic zone, uncover the wonders of the ocean and its diverse creatures.

  1. The Ocean Habitat andHow Animals Evolved to Fit in The largest habitat on Earth: makes up to 97 % of all livable space on Earth Also contains the most unique life forms on Earth

  2. Land Influenced Zones • Better known as: The Neritic Zone • Shallow area of ocean water in which land has an impact • Coastal zones of the ocean • Usually with 3-50 miles of coastline of Continents

  3. Land Un-Influenced Zones • Better known as the: Pelagic zone • Open ocean • Land has no effect or little impact • Majority of the oceans’ habitat

  4. 2 Ways of Moving in Ocean • Nekton- Swim in and out of currents (Most Fish) • Plankton- Drift in Ocean using Currents (jellyfish)

  5. Pelagic or Open Water Zones defined by Light

  6. Pelagic Zones • Epipelagic Zone—0-200 meters in depth • (all colors visible at first) • Mesopelagic Zone—200-1000 meters • (twilight zone: light and dark; no color) • Bathypelagic Zone—1000-4000 meters • (no sunlight visible from this depth and below) • Abyssopelagic Zone—4000-6000 meters • Hadalpelagic Zone—6000-10000 meters

  7. Epipelagic zone adaptations • Counter shading • Concealment: [dermersal (dwelling near the bottom) or vegetal (around plants) ] • Disruptive-stripes or dots • Advertisement • Mimicry-can mimic other animals • Transparent

  8. Countershading

  9. Concealment--Camouflage • Dermersal • Vegetal

  10. Disruptive—stripes or dots

  11. Advertisement—brightly colored--POISONOUS

  12. Mimicry—Brightly Colored—NOT poisonous or copying another life-form • Mimic Octopus

  13. Epipelagic Adaptations • Body Form—Streamed-lined • Musculature-Strong Swimmers • Size-All sizes found here • Eyes-Well developed/large

  14. Mesopelagic Adaptations • Coloration • Black with or without silvery sides • Counter Illumination (glowing organs) • Body formed: Relatively long but sides squeezed in

  15. Mesopelagic Adaptations • Musculature: Moderately strong swimmers some weak • Eyes: Very Large Sensitive eyes

  16. 2 Biggest Challenges for Deep Sea Life • Scarcity or Lack of food; Must evolve way of obtaining food that rarely gets there • Expandable stomachs or great smell • Great Water pressure • 33 ft of water equal same pressure as 36 miles of air

  17. Deep Pelagic Adaptations(Bathypelagic-Hadalpelagic) • Color: Black or red • Bioluminescence-attract prey at times (organs glow)

  18. Deep Pelagic Adaptations(Bathypelagic-Hadalpelagic) • Shape-Globular (round shape)—Large Head • Musculature: Weak swimmers mainly • Fins modified as sensory organs • Size-Most small but some are large • Eyes-Small or absent (eyes if using bioluminescence)

  19. Deep Pelagic

  20. Benthic Zone—Life in the sand • Coloration: Black or Brown • Shape Elongated or flattened • Strong Muscles (to borrow in sand) • Size: Relatively Large • Eyes: Small
