Monographs and Interactive Keys

Introduction

Amphipods are extremly diverse, abundant and widespread crustaceans. They are found in nearly all marine and freshwater habitats. They are paticularly important as herbivores, detritivores, micropredators and scavengers in marine environments and they are almost always an important component of marine and freshwater environmental surveys. For these reasons and many others it is important to be able to identify amphipods. This has always been a problem for non-amphipod specialists because they are usually small, they all "look alike" and they often need to be dissected to be identified. Consequently they are often referred to in published ecological studies and environmental surveys as Amphipods or gammaridean Amphipods.

As far as we know there has never been a family level key to all amphipods. The basis for this work is: Barnard & Karaman (1991) for gammaridean marine familes; Barnard & Barnard (1983), Holsinger (dates) and Barnard & Williams (dates) for the freshwater gammaridean families; Bowman & Gruner (1973) and Zeidler (1992) for the hyperiidean amphipods and Laubitz (1993) for the caprellidean amphipods.

These keys make minimal use of mouthparts for identification purposes and they should almost never have to be used. This means that dissection is minimal and may be confined to taking off the head to get a better look at the anteroventral corner, taking off an anterior leg to see it chelation or a urosome to evaluate the cleftness of the telson.

This monograph currently includes 99 family or family level groups, including freshwater amphipods and the pelagic hyperiideans. A revised version will include all family level taxa except the european freshwater gammarid-like groups.

The family structure of the gammaridean amphipods is problematic. Reanalysis of family structure is currently going on in several laboratories around the world. The basis for the gammaridean family structure used here is Barnard & Karaman (1991), but in some cases there are modifications.

For instance Myers & Lowry (unpublished data) are currently reanalysing the corophioid families which were amalgamated in Barnard & Karaman (1991). Based on these analyses we are using some pre-1991 corophioid families. Lowry & Stoddart (unpublished data) are currently developing a family structure for the lysianassoid amphipods. Not all lysianassoid family groups are formally recognised yet.

We know there are problem areas in these keys and we are trying to solve them. Let us know of any problems you have with the interactive keys and we will try to help solve them.
