Paging Thal!

I have been referring to a particular shrimp as a Periclimenes zanzibaricus, which is what I see over the Internet, but now I am seeing the same shrimp referred to as a Dasycaris zanzibarica.

I don't think they can have two different scientific names for the same species.

Ideas?

interesting! The Genus change is the only difference:

http://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=612260
So are they the same? Or would Geography be enough?

The shrimp look identical and those links even have a cross references to both Periclimenes and Dasycaris, hence the confusion.

I thought scientific names were specifically to avoid confusion! lol.

As far as I can tell both names are current and valid and are not synonymous (they refer to different organisms).

If you want clearer definition call Rafael Lemaitreat, at the Smithsonian, 202-633-0667, you can e-mail him at lemaitrr@si.edu.

Don't be shy ... remember, you pay his salary.

Jim Lyle, made an awesome trip report for an expedition to the Lembeh Straits. He's a noted underwater photographer.

A direct link to his photo can be found here (http://chemistry.csudh.edu/faculty/jim/lembeh2008/xeno4.jpg)

Compare that to the shrimp I shot at the 59 second mark in the top video in this thread (http://scubamagazine.net/showthread.php?t=1825)

Now I get a great kick out of Jim writing in the scientific names of his subjects.....and he identified his shrimp shot as a Dasycaris sp, and I think it is the zanzibarica as in Dasycaris zanzibarica.

I identified the shrimp in my HD video as Percilmenes zanzibaricus.

They look identical to me, hence my confusion.

I found it listed as Dasycaris zanzibarica in my books.

So what is the difference between a Dasycaris zanzibarica and a Periclimenes zanzibaricus?

One is a Dasycaris and the other is a Periclimenes! One was found in the Seychelles and the other in the Philippines?:rolleyes:
