Fishes
Essential Question:
What kinds of structural adaptations
have fish evolved with to adapt to their
environments?
Objectives:
1. To relate the structural adaptations
of fishes to their environments.
2. To compare and contrast the
characteristics of the different
groups of fishes.
3. To interpret the phylogeny of fishes.
• Phylogeny:
– History of the evolutionary relationships of a
group of organisms.
• Based upon similarities and differences in their physical
or genetic characteristics.
