Lotic Communities & Animals
A running water environment offers numerous microhabitats for many types of animals. Similar to plants, animals in lotic communities have acquired evolutionary adaptations to better suit this running water environment. Know more about their evolutionary adaptations in this tutorial...
Still Water Animals
Animals living in aquatic habitats have diversified and evolved through time. They eventually occupy ecological niches available in the ecosystem. Three regions exist in a freshwater environment: profundal, pelagic, and benthic. Get more information on each of these regions and how these regions led to the varying niches that freshwater animals eventually occupied...
Primitive Animals
Life, as we know it today, is presumed to have started in the sea and many of them were likely eukaryotic animal-like organisms. Because of the expanding diversity of animal life forms, taxonomists eventually came up with a classification scheme to group them into various phyla. Know more about the early animals that were likely the first ones to roam the ancient seas through this tutorial...
Freshwater Lentic Communities & Animals
This tutorial looks at some of the communities in freshwater lentic habitats. For instance, symbiosis occurs in a community of hydrophytes providing a substrate for algae. In return, the algae prevent excessive herbivory of hydrophytes by serving as food to the herbivores. Know more details here...
