  author={Karu. Pasupathi and T. Kannupandi},
Larval development of Metopograpsus maculatus under laboratory conditions is described. Five zoeal stages and a megalopa stage appeared at salinity 30 ppt and temperature 29-32 degrees C Larval characters are compared with other known Indian species viz Metopograpsus messor and M. latifrons 
The complete larval development of the Mangrove Ocypodid crab Macrophthalmus depressus Ruppell, 1830 (Brachyura: Macrophthalminae) reared in the laboratory
Macrophthalmus depressus reaches the first crab stage after passing through five zoeal and a megalopa stage requiring 22–23 days, compared with other known species of the genus.
Larval development ofMacrophthalmus erato De Man, 1887 (Brachyura ocypodidae)
The zoeal and megalopal stage of Macrophthalmus erato were obtained under laboratory conditions and are described and figured and their features are compared with those of known species of the genus.
Zoeal stages of the intertidal crab Pachygrapsus marmoratus (Fabricius, 1787) (Brachyura, Grapsidae) reared in the laboratory
This study describes and illustrates zoeas three to six of Pachygrapsus marmoratus and compares them with those in other descriptions of Pachecocephaluslarvae and with undetermined zoea of Grapsidae s.
First zoeal stages of Grapsus adscensionis (Osbeck) and Planes minutus (Linnaeus) (Brachyura: Grapsidae) described from laboratory hatched material, with notes on larval characters of the Grapsinae
The first zoeal stage of Grapsus adscensionis and Planes minutus is described and illustrated and the presence of minute knob-like or hooked projections on the carapace of the zoea I, which in subsequent zoeal stages develop into lateralCarapace spines is proposed as a typical larval feature for subfamily Grapsinae.
First zoeal stages of Geograpsus lividus and Goniopsis pulchra from Panama confirm consistent larval characters for the subfamily Grapsinae (Crustacea: Brachyura: Grapsidae)
Zoea I larvae of the eastern Pacific Goniopsis pulchra and the western Atlantic G. cruentata exhibit differences in size, morphometrics, and setation of the antennule and telson, rendering support to the taxonomic distinction of this trans-isthmian species pair.
Morphology of the megalopa and first crab stage of the mediolittoral crab Pachygrapsus marmoratus (Brachyura, Grapsidae, Grapsinae)
Les caracteristiques morphologiques de la megalope de P. marmoratus sont comparees avec celles des autres megalopes deja decrites d'autres crabes de the sous-famille Grapsinae.
The megalopa and juvenile development of Pachygrapsus transversus (Gibbes‚ 1850)(Decapoda‚ Brachyura) compared with other grapsid crabs
A review of the available information indicated that settlement of large megalopae and fast juvenile development, preceding a precocious sexual maturity, are trends in Grapsinae and Plagusiinae.
A review of studies on Pichavaram mangrove, southeast India
The mangrove harboured a large number of juvenile fishes, especially during summer and post-monsoon, and 90% of the mangroves cover in the study area was degraded, suggesting possible factors that cause degradation of the ecosystem are detailed and remedial measures suggested.
Morphology and growth of the larval stages of Geograpsus lividus (Crustacea, Brachyura), with the descriptions of new larval characters for the Grapsidae and an undescribed setation pattern in extended developments
The larval development of Geograpsus lividus originating from Jamaica and reared under controlled conditions in the laboratory is investigated, representing the longest recorded developmental pathway for any brachyuran.
Molecular phylogeny of the crab genus Metopograpsus H. Milne Edwards, 1853 (Decapoda : Brachyura : Grapsidae) reveals high intraspecific genetic variation and distinct evolutionarily significant units
A phylogenetic inference reconstructions confirmed monophyly of the six species of Metopograpsus and recorded a high intraspecific genetic variation and strong phylogeographic structure within M. thukuhar and M. quadridentatus, indicating the occurrence of distinct evolutionarily significant units within these two taxa.
