WebbIn some species cutaneous respiration accounts for 5 to 40 percent of the total respiration, depending on temperature. Cutaneous respiration is more important in species that breathe air, such as mudskippers and reedfish, … The skeleton is cartilaginous. The notochord is gradually replaced by a vertebral column during development, except in Holocephali, where the notochord stays intact. In some deepwater sharks, the column is reduced. As they do not have bone marrow, red blood cells are produced in the spleen and the epigonal organ (special tissue around the gonads, which is also thought to …
WebbThe shark has evolved efficient structures to minimize energy consumption during respiration. The shark has evolved a way to move water steadily in one direction, instead of in and out of gill slits. During inspiration, lampreys must pump water into the external gill … WebbQuick summary: This lesson incorporates clips from Blue The Film as learning inspiration. Students examine and compare the respiratory systems of humans, sharks and marine turtles. They begin by working as a class to brainstorm what they already know about respiratory systems, and then investigate how human respiratory systems work.
