Marshall Islands Shrimp

This page links to shrimp we have photographed in the Marshall Islands. This is by no means complete coverage of Marshall Islands shrimp. We did not specifically seek out shrimp, but simply photographed those we ran across if it was convenient. In addition, the identifications are often not certain. We have made a few guesses on genera and families of some of our unknowns, but no doubt there are many errors and the names should not be taken as certain. We welcome corrections at uwkwaj@yahoo.com.

Measurements were rarely taken in the field and animals were not collected, so any sizes given are usually very rough eyeball estimates often based on distant memories, and are provided only as a general guideline of what to look for. Estimated lengths include the body from head to tail, but generally not the anterior appendages.

The thumbnails below link to pages with more photos and information on that species.
