One Single Triops isn't called a Triop.  Why?  

Well we asked our expert at the Department of Zoomorphology of Zoological Institute, University of Copenhagen, Ole Sten Møller.  Here is what he had to say on the subject:

Remember that a single member of the genus Triops is not called "a Triop" !!  The genus name Triops must considered a natural "singularis" because there's only one genus of that name. However, this gives us a problem, if we want to use "pluralis". A way around it is to use the orders name Notostraca and calling the little critters notostracans (in pluralis). The singular form then becomes "a notostracan" which sounds as an adjective but isn't. It's usable but it's not quite good.

One might go so far as to leave Latin behind by calling them shield shrimps.  This can be dangerous because one might get "wrong" ideas when using the term "shrimp". (The Notostraca is an order within the class Branchiopoda. What normally qualifies as "shrimps" (for example for eating) are members of the order Decapoda, in the class Malacostraca placing them very far, systematically speaking, from the Branchiopoda.)

The correct way of writing the binominal Latin names is using a capital first letter in the genus name and all other letters in lower case. Furthermore one should use italics (or underline) in both genus and species name . The first time one uses a binominal name it is written in full and the original author is cited (if one has this information) right behind the species name:

The parenthesis indicates that Bosc or Leconte described it first, but it has since been moved to another genus or the genus has been renamed. The species name cannot be changed.

After the first use of the name one is allowed to shorten the genus name down to a single letter eg:

(But as always both should be in italics. Remember that most modern word-processors automatically changes the first letter after the full stop to a capital one, which would be wrong in this case!!)
