The outcome of aggressive contests between alpheid shrimp
depends strongly on the difference in size between contestants (Schein 1977), and in the field, heterosexual pairs of alpheids are more closely matched by chela size than by body length (Knowlton 1980).
Mechanisms for the snapping behavior of two alpheid shrimp
, Alpheus californiensis and Alpheus heterochelis.
The nine chapters in the sections on General Biology and Ecology review an array of topics for which gobies are already well-known, such as the mutualistic association between gobies and alpheid shrimps
, the cleaning behavior of Elacatinus species, and the excavation of burrows by mudskippers, and those for which they are less so, such as their life as predator and prey.
Morphological phylogeny of alpheid shrimps
: parallel preadaptation and the origin of a key morphological innovation, the snapping claw.
We thank Mike Neumann for his assistance in collecting and photographing the type specimens of the new species, Arthur Anker for the identifications of the symbiotic alpheid shrimps
, and Gerald R.
Species found in shallow waters are known to live with alpheid shrimps
. Information is presented here to clarify the identity of some of the previously described species, which have been confused or believed incorrectly to be undescribed.
Taxonomic review of four alpheid shrimps
belonging to the genus Athanas with reference to their sexual phenomenona.
