  9. Cent. Amer. Freshwater Fauna: Decapods • Crabs • Shrimps

  10. Central America Freshwater Fauna: Other Vertebrates Amphibians(VERY low salinity tolerance) • Frogs – larvae VERY important in sm. streams • Salamanders – esp. larvae • Caecilians Reptiles (includes Birds)(higher salinity tolerance) • Turtles • Crocodiles and Caimans • Various Birds – waders & divers Mammals(refer to Kleier presentation)

  11. Central America Freshwater Fauna: Typhlonectes sp.

  12. Cent. Amer. Marine Fauna: Fishes Shallow-Water Fishes - Reefs (coral & otherwise), sandy shores, rocky shores, eelgrass beds, & mangroves Various body shapes and a wide range of camouflage and advertisement colors. Open-Water Fishes Usually streamlined body shapes and silver, gray, or dusky blue color. Deep-Water Fishes - (won’t talk more about) Various body shapes and black, bright red, or silvery color… often with photophores.
