This is such a terrible idea I have no option but to share it. We all need to know how good a site or destination is, but it's hard to get across in a succinct manner. I thought - why not a points system, based on points accrued for sightings of certain marine creatures? The idea is not to find as many of one type as possible, but to note that at least one has been seen, tick it off your list and add the points up.
The problem, of course, is how many points to ascribe to said critters. For instance, how would you rate a bobtail squid as opposed to, say, a harlequin ghost pipefish? In the end, subjectivity is the only route (and probably also the reason why my idea is terrible, and thus doomed). I drew up a list of critters and gave them all points out of 10, based on rarity and general appeal. Vulgar, eh? Anyway, I did it, and here's the list. Additions, opinions and outrage are all welcome.
