Goddamn taxonomy

Well I have not posted in a while and so today I will post some complaints I have with the work I do... Now just to clarify, I like my job... And I understand the work we do is important, and I do not want to sell it short... But I do have serious issues about the way things get identified...

For example, Thor shrimp... My problem is this... Supposedly 2 species occur in the area, Thor manningi and Thor floridanus... The former has a rostrum that is armed but sometimes unarmed and has the 4th pair of walking legs it 3, sometimes 4 or 5, spines, not including the dactyl pair.... The latter is unarmed but can be armed, has 4 or 5 but sometimes 3 spines on the fourth walking leg... Honestly, wtf??? Both can look exactly identical, occur in the same areas and still be different... Who came up with this anyway??? Especially when carridean shrimp can be sexually dimorphic and we rarely, if ever, get gravid T floridanus... I just think its quite possible that they are the same species and want to know how people 100 years and 30 years ago came up with something otherwise...

Similarly Hippolyte shrimp that we get are very much the same... H zostericola and H pleuracanthus exhibit similar rostrums, however, the latter is supposedly much shorter (not extending beyond the antennule scale)... The problem I have with this is that we often get large batches of Hippolyte shrimp... And all the large ones are always H zostericola, and usually over 65% gravid, and all the supposed H pleuracanthus are small, juveniles and never, ever gravid... Again, many carridean shrimp are sexually dimorphic.... I just want to know where these people came up with the separate species (some literature suggests its a mistake that they should be considered the same species)...

And I don't even want to start on mud crabs, which a recent paper suggests through DNA sequencing that they aren't as many species or even genera as we are calling them...

I guess my big problem is that we are trying to identify things that we cannot identify, especially with none of us being carridean shrimp experts... And with all this information that perhaps they are the same that we still have to call them differently really bothers me... But oh well... I am just venting... Needed to post something, so this is it... Now you know a little more about what I do at work....
