Valpo, a crabby type locality

A while ago I found out that a whole generic group of crabs had been named after me. So, it was quite surprising to find Chirinocarcinus as a name for a new genus of xhantoid crabs. I had been honoured because I had done some work on other crustaceans before describing some new species such as the big deep-sea crab Chaceon chilensis (photo above) living off Valparaiso all the way to Easter and Juan Fernandez islands plus a few fossil south american species. Doing these studies I had to check the historical localities where many species had been collected and I found out that for many of the older ones the type locality for the holotype of the species was Valparaiso. So among other chilean localities, Valparaiso has a curious distinctive feature to be cited as the most frequent chilean type locality for many animal and botanical species, especially those from the seashore collected originally in the XIX century. This is especially true for marine invertebrates such as crabs that were the focus of my earlier learning on taxonomy. Probably, today nobody could collect most of those species found originally at Valparaiso because environmental change... i.e. pollution. Of course, despite fishing some of them still might be doing well because today there is more available food for them so there are more smaller detritus eating cancrid jaibas than in older times. Anyway, most of those fished here end in dishes such as the pastel de jaiba, but don't ask what they eat...
