Document Summary
Animals come in a range of body sizes. Rotifer: 0. 0001g (10-4g), blue whale: 177 000 000g (108g) 12 orders of magnitude difference huge ratio of sizes. Blue whale is the largest animal that ever lived. Compare: bee hummingbird 1. 8g vs african ostrich: 130 000g. Even invertebrates come in a range of body sizes (i. e. colossal squid: 495 000g) Relationship between size and other things is not necessarily a 1:1 relationship (cid:498)structural and functional consequences of changes in size or scale among otherwise similar organisms(cid:499) leg length: body length doesn(cid:495)t change with size. Proportions stay the same with changes in size. As a frog grows in size, the ratio between its body size and leg length remains the same. Get a line with a slope of 1 body that is twice as long, you get a leg length that it twice as long.
