Animal Adaptations of the FRESHWATER AQUATIC BIOME - Coggle Diagram
Animal Adaptations of the FRESHWATER AQUATIC BIOME
bottom layer of open water with low light penetration
Animal types you may find in the
PROFUNDAL ZONE
Phylum Platyhelmintes: Flatworms
(planarians)
branched gastrointestinal cavity that diffuses nutrients
eyespots that detect light, simple brain with nerve cords extending down body
Hermaphroditic, may swap sperm or reproduce asexually
Bony Fishes (blue gill, bass, walleye)
Swim bladder for bouyancy
have lungs and can breath without swimming (operculum)
Lateral line system to detect prey from vibrations
zone nearest shore
Animal types your may find in the
LITTORAL ZONE
Phlylum Arthropoda (crustaceans like crawfish)
Appendages for walking (legs) and swimming (swimmerets)
Metamorphosis: allows different life stages to not compete for resources
exoskeleton to conserve water while on land
Amphibians (frogs, toads)
Larger bones for weight bearing
Still utilize aquatic environment for reproductive stages
First tetrapods: four limbs for walking on land
Distinct neck for independent movement
Larger and more complex lungs for breathing air
Changes in inner ear to detect airborne sounds
Phylum Mollusca (snails, bivalves such as clams)
open circulatory system
Gills (in water) or lungs (terrestrial)
mantle, visceral mass, foot
top layer of open water where light penetrates
Animal types you may find in the
LIMNETIC ZONE
Phylum Annelida (Leeches)
Bilateral and segmented body
Scavengers
Closed circulatory system: blood travels to and from the heart
Phylum Reptilia (birds like ducks, geese)
Endotherms-maintain their body temp internally through their metabolism.
Adaptations for flight
Feathers
larger eyes, bigger brains
Hollow bones (light weight)
Amniotes: have eggs that survive on land because they are enclosed in a fluid series of membrances
Phylum Anthropoda (insects like dragonflies)
three part body plan: head thorax and abdomen
evolution of wings for better disperal
Respiratory system that conveys air from the insect's surface to the inside of the body.
