When are the strongest tides?
When are the weakest tides?
13. Raccoons:
 Physical adaptation?
14. Bull Kelp (Seaweed):
 Physical adaptation?
15. Sting Rays
 Physical adaptation?
16. How do the tides vary at the equator?
17. The thimble jellyfish would be considered ( plankton / nekton / benthos ).
18. The jellyfish have a symbiotic relationship with another organism. Describe it.
This is an example of ( mutualism / commensalism / parasitism / competition )

 Physical adaptation?
20. Why do the larger sea predators not hunt during low tide?
21. Giant Horse Conch
 Physical adaptation?
22. Hermit Crabs
 Physical adaptation?
 The hermit crabs show an example of what kind of relationship? __________________
23. How does the composition of the water in mangrove swamps change with the tides?
24. How does the ecosystem of low-lying islands (e.g. Bahamas) change with flooding?
25. Caribbean Flamingo
 Physical adaptations:
