What Does Your Sawfish Eat?
There are 5 species of sawfish, determined by their body shape and teeth placement on the rostrum. Based on these differences, students will attempt to answer if there is an affect on the diets of these species. Students will design and build scale models of the rostrums of the five species (dwarf, long tooth, green, small tooth, narrow) and test which size marine wild life can be caught with those models. Students will explore scale models, species diversity, and adaptations. Students will also be engineering the rostrums from diverse materials, allowing for creativity in their model design. To construct their models, students will be using data from wildlife biologists who have categorized sawfish based on tooth size and tooth placement on sawfish rostrums.
