Labelings of the Spiny Dogfish Shark
Organs of the Spiny Dogfish Shark
- Gallbladder- functions in storage and flotation
- Heart- two halves; the atrium and ventricles, special muscle
- Kidney- balance salt and water; and eliminate toxic wastes
- Liver- holds the oil that gives the shark buoyancy many digestive functions happen here such as strong nutrients and food molecules that arrive at the gut
- Pancreas- secreases many digestive enzymes
- Small Intestine-there is a fold in the intestine that allows the shark to eat more food and it is stored here
- Large Intestine-the waste goes into the large intestine and also reclaims water here
- Stomach-storing food eaten by the shark, until digested
- Esophagus-passing food from the pharynx to the stomach
- Rectum-the elimination of feces
- Claspers-a finger like projection, that help with sperm transfer during mating, only in males!!!
- Lateral Line- can sense tiny water movements, such as those made by swimming prey
- Gills- they take oxygen in from water passing over them and let out carbon dioxide
