There are n number of sharks, where n is between 0 and the maximum number of possible sharks.

SHARKS!

At least three that I can think of and know personally. I can't comment on the rest.

thanks for your help so far. i'm thinking of taking this project in a slightly different direction, since there are no dinosaurs left my graph looks silly, and i don't want to discount dinosaurs as an anomaly as they are my favourite.

so instead i'm going to construct a similar graph, plotting rating from 1 to 10 on the x-axis (this will help by creating 10 'categories' so that i'll be able to do standard deviation more easily when drawing my line) against the number of that animal that has existed ever, in comparison to sharks, with sharks being 1.00, as it they are the most numerous in history that i like enough to be included in the graph, and all other animals being related to that number, for example dinosaurs would be 0.351. you will notice that i'm using 3 significant figures, this is so that the results are more accurate, otherwise there would be multiple 0.4s or 0.35s.

i'm doing this* instead of my real assignment, which looked a bit hard so i decided i wouldn't do it.

*i'm not really doing this.
