However, here are some of the widely accepted examples of commensalism found in nature. Examples of Commensalism Cattle Egrets and Livestock One of the popular examples of commensalism is the relationship between cattle egrets and livestock. The cattle egret is a common species of heron that is found in most regions of the world, and is mostly seen moving along with herds of cattle.

They are different from other types of scorpions in the way that they do not have stingers. Some species of the pseudoscorpions hide themselves under the wing covers of large insects like beetles.

Video clips on symbiotic relationships Activity: Assessing Ask students to divide their journal page into 3 columns. Ask students to title the page symbiotic relationships. Explain to students that they will be observing videos of the 3 different types of symbiotic relationships.

Note which organism benefits, is harmed or is unaffected. Use the classroom computer to project the following site: Ask students to give a brief definition for the word symbiosis and have them place a new term at the heading of each section of their journal that identifies each of the 3 relationships: Ask a few volunteers how they identified each section. Select one video from each section to share with students.

Take time after the clip to see under which heading they classified the relationship and why.

Ask students to write the name of the term in the center of their box. In the top left corner they will be describing the concept. In the top right corner they will be adding something that will help them remember the concept. In the bottom left corner, students will draw a picture to help them remember the concept, and in the bottom right corner they will give an example of the term. With a partner have students complete the description for each concept. Stop and discuss the relationship, if it is mutualism, parasitism, or commensalism.

Have students add new information to their Frayer models. Other video links can be found at: Assessing Review the terms symbiosis, mutualism, commensalism, and parasitism with students.
