Gaseous Exchange in Fish

Countercurrent Principle – blood and water are flowing in opposite directions

across the gills

Schooling Patterns in Fish

Page 18: Marine Fish Part 1. MARINE FISHES Fish Are Divided Into Three Classes.

Why Do Fish School?

• Protection?

• Hydrodynamics of Swimming?

• Feeding?

• They Want Better Paying Jobs?
