Ocean life ranges in size from the smallest virus to the largest animal that has lived on Earth, the blue whale. Some major groups are found exclusively in the ocean.
The diversity of major groups of organisms is much greater in the ocean than on land. Ocean biology provides many unique examples of life cycles, adaptations and important relationships among organisms such as symbiosis, predator-prey dynamics and energy transfer that do not occur on land.
OLP 5d To build an understanding of how the ocean supports a diversity of living organisms and ecosystems, it is important to learn about the biology of amphibians, reptiles, and birds.
These concepts will be explored in this unit through the following activities and investigations: Activity Use a simple dichotomous key to correctly identify amphibian major groups.amphibians reptiles an introduction to their natural hi Online Books Database Doc ID 6cc Online Books Database Amphibians Reptiles An Introduction To Their Natural Hi Summary of: amphibians reptiles an introduction to their natural hi on a nature hike or exploring in your neighborhood youll want to take along a copy of this.

Dinosaurs lived on the land, ichthyosaurs and plesiosaurs swam the oceans and pterosaurs flew about in the air.
These animals however, have long since disappeared, but there are still more than different. General Information (and "FAQ") But strictly speaking, reptiles are not that easy to define. Phylogenetically reptiles are not an isolated evolutionary lineage like birds.
In fact, crocodiles are more closely related to birds than to lizards, so the birds should be part of the reptile class as well. As Thiele and Yeates (Nature ,
