1- Which geological period saw the highest diversity of fishes? List the three main groups of armoured fishes that coexisted and radiated in this period and their main characteristics. Provide some possible explanations for their extinction.

2-Explain how a white shark (Charcharodon charcharias) located 2 km away from a sea lion (Family Otariidae) can successfully detect and capture it. Describe all the possible senses and anatomical structures involved in providing information to the shark as it homes in on the unsuspecting sea lion. Also include in your answer the predation strategy of the shark, from attacking, to killing and eating its prey.
