(NISCAIR, CSIR, 2000)
The relationships observed between total carapace length with carapace width, carapace weight, telson length, body weight were found statistically significant (p < 0.05) in the male and female horseshoe crab, Tachypleus ...
Effect of lunar periodicity on the abundance of crabs from the Goa Coast
Lunar periodicity showed a significant influence on the occurrence of edible crabs (@iPortunus pelagicus, Charybdis cruciata and Portunus sanguinolentus@@). High density of these crabs was recorded in the trawl catches ...
A freak twin trilobite larva of the Indian horseshoe crab Tachypleus gigas (Muller)
(Bombay Natural History Society, 1993)
Early embryonic stages of a horseshoe crab Tachypleus gigas were studied using micrographs of live embryo. A freak egg showing two trilobite larvae bridged with each other was noticed on 38th day after fertilization. ...
