Abstract

The zonation and distribution of crabs were studied in Pichavaram mangrove
swamp. The season-wise distribution of crab species was maximum among the
managal trees, especially Rhizophora and Avicennia species and open mud flats
with mixed forests. Twenty three species of crabs were recorded from the mangrove.
The species richness of crabs was higher in creek mangrove vegetation than
in fringe mangrove types. Comparisons showed that the species composition of
the crabs in the Sesarma zone was widely varied when compared to other
Cardisoma, Ocypoda, Uca in mixed zones. More population and high species composition
were recorded in the postmonsoon period. Each zone exhibited in characteristic
species diversity. Distribution and zonation of crabs were based on the
substratum, water level and floral distribution.
