This butterfly is an example of bilateral symmetry. If you cut the butterfly into two planes, both halves are mirror images. Bilateral symmetry is a symmetrical arrangement of parts of an organism along a central axis.
These goldfish at Petsmart are described as an ectotherm. Fish, lizards, snakes, and frogs are all examples of ectotherm animals, because they are considered cold-blooded animals due to not being able to regulate thier own body temperatures. They have to adapt to their surroundings or environment.
This chicken egg is an example of an amniotic egg. The embryo develops inside an amnion which is the innermost lining of an egg and it encloses the embryo. These type of eggs are made from reptiles, birds, and egg-laying mamals.
Both of these photos are examples of analagous structures. The wings of the bird and the wings of the misquito are features of different species but have the same function to fly.
This warm-blooded animal called a territoral heifer with a calf is an example of a endotherm animal. Unlike ectotherm which are cold blooded animals who can not regulate their body temperature; endotherm generate heat to maintan its body temperature which is usually above the temperature of its environment. (P.S. I was almost ran over by this cow Mrs. Lory so all I got to say is I hope you like it, and I miss my own cows.)
