Juvenile and adult Tambja abdere

May 26, 2002
From: Peter Ajtai

Dear Bill,
Here is a photo of a juvenile (I think, it was much smaller than the adults) Tambja abdere and an adult T. abdere. What are continuous straight lines of yellow in the juvenile, seem to break up into discontinuous lines in the adult.

Unfortunately, these aren't pictures of the same individual, so I don't know what the juvenile is going to grow up to look like...
The photos were taken by Ingo Wehrtmann.

The juvenile was found in tide pools at neap tide in Tamarindo, Costa Rica in March. The adult was found on April 25, off of Isla Pelada at 40ft, in the Islas Murcielago chain. Isla Pelada is composed mostly of serpentine rock.

Just thought the photos were interesting. Especially with the continuous blue line and blue spot variability in Tambja eliora.
Take care,
Peter Ajtai.

Thanks Peter,
Photos showing colour variation are always of interest. The juvenile hasn't as yet developed any yellow on the outside edge of the gills.
Best wishes,
Bill Rudman
