Perch Lab
- The fish is streamlined, skinny, flat, and long. In the water the least amount of friction is required to service because of the the vastly higher viscosity of water compared to air
- The gill rakers prevent particles form damaging the gills
- The scales face the posterior side to allow the fish to be more streamed lined.
- The fish has 4 of nostrils. They only using them for smelling.
- The gills have water constantly flowing over them making them very effective.
- The lateral line can detect vibrations in the water.
- The endoskeleton allows for more fluid motion.
- The guppy will have a higher survival rate for it's young, however the perch will produce more offspring.
omparative Structure and Functions:
Chordates are the most advanced phylum in the animal kingdom. Chordates all have three germ layers, bilateral symmetry, and a well developed coelom. Endoskeletons, sexual reproduction between male and female organisms, and brains with spinal chords are advancements that have allowed chordates to become so advanced and successful. Chordates also have segmented muscles which allow for advanced movement with larger bodies.
Taxonomy:
The phylum Chordata is a large phylum which contains animals that have a notochord at some stage in their development. The phylum has the subphylum Tunicata, Cephalochordata, and Vertebrata. Organisms in Tunicata are marine invertebrates such as Sea tulips. Cephalochordata is a very small subphylum, with only thirty species. These organisms are all primitive marine chordates in the class Lancelet. Vertebrata is the largest subphylum by far, with 57,000 species. These organisms are very diverse, but all have a vertebral column. Members of this group include cats, dogs, bears, deer, and humans.
Ecology:
To be classified as a chordate, an animal must have, at some point in its life, a dorsal, hollow nerve cord, a notochord, pharyngeal pouches, and a tail that extends beyond the anus. Chordates are both predators and prey to many organisms. Some chordates, such as mice, are prey for many types of larger organisms, while other chordates, such as lions, eats many types of smaller organisms. Chordates can be carnivores, omnivores, or herbivores. This diverse phylum is essential for the survival of our ecosystem.
