Give the shared characteristics of the following animal groups:
1. Ray-finned fishes & Lobe-finned fishes
Step by step
Solved in 3 steps with 1 images
- Give the shared characteristics of the following animal groups: 1. Lobe-finned fishes & Amphibians 2. Amphibians & Reptiles (including birds) 3. Reptiles (including birds) & MammalsExplain how bony fishes differ from sharks and rays in the following systems or features: skeleton, scales, buoyancy, respiration, and reproduction.Describe the traits common to all fishes.
- Bony fishes are divided into which two groups? a. hagfishes and lampreysb. sharks and ray-finned fishesc. ray-finned fishes and lobe-finned fishesd. jawless fishes and cartilaginous fishesCompare the overall body plan of the prawn to that of an insect like a grasshopper (see drawings below). Provide a complete side-by-side analysis of the two groups that would include body regions, and appendages. Focus your comparison on how the two groups have adapted uniquely to their environment. MacBook Pro く※ $ 4 5 8. R T Y U の く○1. Observe the behavior of the live goldfish. Note the movement of the operculum. What is its function? Does a shark have an operculum? 2. Examine the model of the bony fish. Compare the fins, shape of the tail, scales and other external features with the shark. How do the fins of fish contribute to the evolutionary story of animals evolving to life on land? 1. Observe and compare the features of the amphibian specimens. 2. The frog will be used to review vertebrate anatomy. Begin by examining the thin skin of the frog. How does it compare to the skin of a reptile? Would the frogs skin help protect it against water loss? How is the frog able to supply its body tissues with enough oxygen even if there is some mixing of oxygenated deoxygenated blood? Amphibian, literally means “living on both sides”. Explain why amphibians have that name. What characteristics do reptiles have that make them more suited for terrestrial life than amphibians? Why are birds thought of as flying…
