Redfin Pickerel :: essays research papers

Description: The Redfin pickerel has 15 to 36 dark, wavy vertical bars and reddish-orange lower fins. The coloration is much the same as that of chain pickerels, a dark backward slanting bar below the eye. The snout is shorter and broader than any other pickerel. There are normally 11 to 13 branchiosstegal rays under the lower jaw. The cheek and gill covers are completely covered in scales. They weigh up to one and a half pounds, which is the world record to this day. They have an average length from 6-10 inches with an average weight of 5 ounces. The Redfin Pickerel has a cylindrical, torpedo-shaped body with numerous sharp teeth at the point of the snout. Range: The range of the Redfin pickerel is found statewide with the exception of mountain habitats. Environment: They are usually found in heavy growths of aquatic plants in sluggish streams. They are also found in shallow coves of lakes or in ponds. They prefer water from 75 to 80 degrees. Redfin pickerels may be the dominant predator fish in small creeks. They prefer slow moving, heavily vegetated swamps and millponds. Food: Small fish make up most of the Redfin pickerels diet, but they also eat aquatic insects and various other invertebrates. Reproduction: The Redfin pickerel spawns in the early spring as water temperature approach 50Â °F. Spawning occurs in shallow water when the female deposits her eggs in vegetated areas where they are fertilized and left unattended. A large female may deposit as many as 4,000 eggs at one time. Some fish as small as 5 inches may release no more than 400 eggs. They become sexually mature by at least age two. No parental care is given to the eggs. Unique characteristics: The Redfin pickerel has numerous sharp teeth in a relatively pointed snout making it perfectly designed for its ambush-type-feeding behavior. Due to small size, sport fishing for this species is limited to coastal areas where the ideal habitat for growth exists. This fish is highly prized by many low country natives who grew up eating this sweet flavored fish.

Introduction to Biology Name: Julie Maxwell Classifying Arthropods Virtual lab (Week 8) Go to the following website for completion: http://www. mhhe. com/biosci/genbio/virtual_labs/BL_18/BL_18. html Upon completion of the Classifying Arthropods Virtual Lab, please answer the following questions thoroughly using complete sentences and proper grammar and spelling. Data Table | Body Sections(1,2,3, or >3)| Walking Legs (6,8 or >8)| Other Appendages| Antennae(0,2 or 4)| Claws Present? | Jaws Present? Class| Common Name| Specimen 1| | | | | | | | | Specimen 2| | | | | | | | | Specimen 3| | | | | | | | | Specimen 4| | | | | | | | Beach Hopper| Questions: 1. Many species of arachnids are predators, but have no teeth or jaws. How do they obtain nutrients from their prey? They inject venom in the prey that paralyzes them then the predators suck out the nutrients they need. 2. Arthropods are the most diverse group of animals. Describe some characteristics of arthropods that may have cont ributed to their great evolutionary success.The body segmented, the segments usually grouped in two or three rather distinct regions – making them highly mobile. * Paired segmented appendages (from which the phylum gets its name) – making them ambulate & walk easily. * Bilateral symmetry – making them relate to the environment quite easily. * A chitinous exoskeleton, which is periodically shed and renewed as the animal grows – making them resistant to shock of hard objects. * A tubular alimentary canal, with mouth and anus – accounting for good food digestion. The circulatory system an open one, the only blood vessel usually being a tubular structure dorsal to the alimentary canal with lateral openings in the abdominal region – ensures better perfusion and less chances of hemolysis due to their being highly mobile. 3. What are some advantages and disadvantages of having an exoskeleton? Advantages are, the exoskeleton provides a bony plat e of armor for support and protection of the soft internal tissues and organs. Disadvantages; it limits the possible size of the animal.Since the weight of an animal is a function of its volume, a doubling of an animal’s size increases its weight by a factor of 8. 4. Which of the five classes of arthropods is the most diverse? Explain. Insecta or Hexopoda (insects) is the most diverse class. There are about 900,000 known insect species, three times as many as all other animal species together, and thousands of new ones are described each year. They are commonly grouped in 27 to 32 orders, depending upon the classification used. The largest order is that of the beetles (Coleoptera).Next, in order of size, are the moths and butterflies (Lepidoptera); the wasps , ants , and bees (Hymenoptera); and the flies and mosquitoes (Diptera). Other major orders are the true bugs (Hemiptera); the cicadas , aphids , and scale insects (Homoptera); the grasshoppers and crickets (Orthoptera); the cockroaches (Blattodea); and the mantids (Mantodea). 5. For each of the following characteristics, indicate whether the trait is common to Phylum Arthropoda or specific to certain classes of arthropods: wings, chewing mouthparts, jointed appendages, number of legs, segmented bodies, type of respiratory structure, exoskeleton.
