Isolines Map (with a Bonus)

http://www.scielo.cl/fbpe/img/rchnat/v76n2/img14-07.gif
Isolines are akin to contour lines. Both are types of hypsometric maps, which we have seen earlier. Isolines form lines based on equal value. (Elevation lines are one type of isolines and were described in a previous post.)
This maps shows ocean depth and Caprellidea (skeleton shrimp and whale lice http://animaldiversity.ummz.umich.edu/site/accounts/classification/Caprellidea.html).
It is a nice GIS sample; it also uses porportional circles for the Caprellidea population.
