  1. Percidae Family Phylum: Chordates

  2. Unique, Shared Characteristics of the Chordates Most chordates have a notochord – rod of cartilage that in found inside the body which turns into the spine Dorsal neural tube which creates the spinal chord Pharyngeal slits or the pharynx found behind the mouth with the throat A tail that extends from the anus Endostyle – a groove in the ventral wall of the pharynx

  3. Habitat Perch live in a wide variety of habitats. - Mainly found throughout Canada and North Eastern United States - Prefer fresh waters with lots of vegetation - Generally live in warm or cool waters - Shallow waters

  4. Adaptations of the Perch • Large eyes • Spines • Thin, shorter disc shapes • Striped colouration • Light coloured bellies

  5. Food Processing and Excretion • Food ingested in mouth • Broken down in esophagus • Digested in stomach • Processed in pouches called pyloric caecum • Pyloric caecum excrete digestive enzymes and absorbs nutrients • The liver and pancreas adds more chemicals to the food as they move through the digestive tract • Finally the food reaches the intestines to finish the digestive system • most fish excrete nitrogenous waste such as ammonia • Other waste diffuse within the gills of the fish and blood waste is filtered by the kidney

  6. Osmoregulation • Saltwater fish tend to lose to the outside due to osmosis but the kidney returns the lost water • The reverse is done for the freshwater fish

  7. Sensory system • The Brain is divided into mainly three parts • Forebrain, Midbrain, and Hindbrain • Forebrain – controls and processes signals that come from the nostrils • Midbrain – associated with signals that are involved with sight • Hindbrain – largest part of the brain; involved in balance and swimming • Chemoreceptors – create the sense of taste and smell • They also have sensitive receptors outside their bodies to detect vibrations and currents to notice other fish nearby

  8. Circulatory System • Fish have a closed loop circulatory system • Heart pumps blood in a single loop throughout the body • The heart is made up of four parts • Sinus venous, atrium, ventricle and the bulbous arteriosus • Sinus venous – a sac that collects blood from the veins before moving it to the atrium • Atrium – muscular chamber that sends blood to the ventricle • Ventricle – another muscular chamber that pumps blood to the bulbous arteriosus and then out of the heart • Bulbous arteriosus – large tube that connects to the aorta and allows blood to flow to the gills

  9. Respiratory System

  10. Fertilization and Reproduction - External sexual fertilization - Spawn in the spring time - Generally at night time - Do not care for their young • Eggs are laid in aquatic vegetation

  11. PREPARE FOR DISSECTION
