Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny [ 1 ] (the evolution of species). The science began in the classical era , continuing in the early modern period with work by Pierre Belon who noted the similarities of the skeletons ...
The amphiuma's predatory behaviors and food selection are very calculated and variable depending on abundance of food. In addition to eating frogs, snakes, fish, crustaceans, insects, and other amphiuma, amphiuma have been found to eat annelids, vegetables, arachnids, mollusca, and larvae. [12] Amphiuma seem to have a preference for eating ...
An expanded three link energy food chain (1. plants, 2. herbivores, 3. carnivores) illustrating the relationship between food flow diagrams and energy transformity. The transformity of energy becomes degraded, dispersed, and diminished from higher quality to lesser quantity as the energy within a food chain flows from one trophic species into ...
Plant fruit: the fleshy nutritious part of plants that animal dispense by eating independently came about in flowering plants and in some gymnosperms like: ginkgo and cycads. [239] Water transport systems, like vascular plant systems, with water conducting vessels, independently came about in horsetails, club mosses, ferns, and gymnosperms. [240]
An affinity between the amphibians and the teleost fish is the multi-folded structure of the teeth and the paired supra-occipital bones at the back of the head, neither of these features being found elsewhere in the animal kingdom. [25] The Permian lepospondyl Diplocaulus was largely aquatic
Nevertheless, the sites for muscle attachment on the palate were more well-developed than those of contemporaneous amphibians. White extrapolated that Seymouria was a mostly carnivorous generalist and omnivore, feeding on invertebrates, small fish, and perhaps even some plant material. It may have even been cannibalistic according to his reckoning.
They are most active in cold temperatures, specifically between 9.1 and 20.2 degrees Celsius. [16] [17] During the day, N. maculosus seeks refuge under rocks or logs and plant debris. [15] They forage during the night and eat a variety of prey, but have preference for crayfish. [4] During the winter and spring, N. maculosus will also eat fish. [5]
The food residue passes into the large intestine where excess water is removed and the wastes are passed out through the cloaca. [77] Although adapted to terrestrial life, frogs resemble freshwater fish in their inability to conserve body water effectively. When they are on land, much water is lost by evaporation from the skin.
