  1. Kelp Forest

  2. Kelp • Largest type of brown algae • Up to 100 m long • Grow up 1 ½ - 2 feet/ day • May form dense beds or forests

  3. Structure of Kelp Pneumatocysts

  4. Abiotic Factors • Restricted to cold water • Sunlight • Hard substrate • Located down eastern shores of ocean

  5. Biology of Seaweeds – Kelp Beds and Forests Kelp is the collective term referring to very large brown algae dominating cold water regions of the earth.

  6. Spring Upwelling fertilizes kelp Abundant plankton, fish feed Summer Rapid growth Autumn Relatively calm Winter Stormy Many kelp torn up Seasons in Kelp Forest

  7. Biology of Seaweeds – Kelp Beds and Forests If the algae do not form a surface canopy, the algal communities are referred to as kelp beds. If the algae do form a surface canopy, the algal communities are referred to as kelp forests.

  8. Abundant Animal Life • Kelp feeders • Top snail • Sea urchins • Scavengers • Kelp crabs • Decorator crabs

  9. Other invertebrates • Brittle stars • Sea stars • Crabs • Octopuses • Fish • Giant kelp fish • Garibaldi • Opaleye • Halibut • Tubesnout

  10. ☺☺☺Sea Otters☺☺☺ • Smallest marine mammal • No blubber • Spend lives in oceans • Anchor to kelp when sleeping

  11. Kelp forests affected by climate El Nino La Nina
