Panama lobster

[Jennifer Anna Bossung]

Hello all- I have a question regarding two types of lobster found in 
Caribbean waters (specifically off the coast of Panama).  The first is a 
migratory form, locally known as "pinky," which travels (or used to 
travel) south from Nicaragua to Panama in large groups.  They are supposed 
to be characteristically pink in color (when alive).  The second type is 
locally called "obia," and has green-tipped appendages.  Can anyone tell 
me what the scientific names of these critters are?  Thank you, Jenna
