Chapter 7 Life history
Case study: Nemo
2-6 clownfish spend their entire adult lives within 1 sea anemone but are not
largest fish = female, second largest = breeding male
remaining fish = immature non breeders

Chapter 8 Population Distribution and Abundance
Case study: Kelp forest to Urchin Barren
Are very diverse organisms and are dense forest like stands (bornw)
Urchin barrens many sea urchins, very little kelp, low species diversity
o sea urchains bite thr
Chapter 4: Physiological Ecology
Case study: frozen frogs
Some animals withstand semi frozen state
They survive winter in shallow burrows with no heartbeat, no blood
circulation and no breathing
Very few vertebrates can withstand freezing
