What does it mean??Possible reasons exposed side ispreferred…• Predation• Nutrient flow
Conclusions
Possible errors:• Difficulty in identifying
areas of impact• Identifying most
representative sample
Hypothesis was disproved!
The wave watcher. Safety first!
Future Projects
• Survey the area ahead of time• Take physical measurements• Research the various organisms
