WebThis collection details the anatomy of a sea star (starfish). WebIn this dissection lab, your students will step into the role of a biologist and examine the anatomy and physiology of a fish critical to habitats in the Great Lakes region. Students perform an external and internal physical examination to determine the health of their specimen based on fish anatomy and physiology.
WebA fish swimming in the water expends less energy if it is neutrally buoyant (that is, it neither sinks nor floats). If this fish starts to descend, the increased pressure from the water surrounding the fish results in a compression of the gas inside the swim bladder. The fish becomes negatively buoyant and will tend to sink. WebFish dissection guide Internal Anatomy: 1. Incision at anus. Begin by inserting a fine scalpel blade into the anus (also called the vent) of the fish. The anus is located just anterior to (in front of) the anal fin, on the ventral (lower) side of the fish in most fishes. 2. Cutting anteriorly. The incision is then extended anteriorly
