Glowing in the Dark: Adaptations to Living in the Deep Sea Presented By: The North Mississippi GK-12 Project The University of Mississippi NSF North Mississippi GK-12
Who Makes Light • Some bacteria • Some wood fungus • Some insects (e.g. fireflies) • Dinoflagellates • Deep sea organisms (e.g. squid, comb-jellies) But not people! NSF North Mississippi GK-12
The Deep Sea • Over 1,000 feet below the sea • Little to no sunlight reaches bottom • Barren (plants can not grow) NSF North Mississippi GK-12
Animals of the Deep Sea NSF North Mississippi GK-12
What Color of Light is Made • Most deep sea organisms make blue light However, some animals make both blue and red light Can you think of why they makered light in addition to the blue? NSF North Mississippi GK-12
Why Make Light Light helps animals find one another Some fish (e.g. loosejaws) use red light as “night vision” goggles NSF North Mississippi GK-12
How is Light Made and Seen Light is made from light producing organs via a chemical reaction Light is seen with photoreceptor cells NSF North Mississippi GK-12
