Abstract

The post-naupliar developmental stages of Temora turbinata (Dana) (Copepodites I to VI) are described and illustrated. The differences in the meris ic characters associated with growth have been investigated. The segmentation and setation of the maxillipeds of copepodid stages offer important criteria for separating the different stages. Special attention has been given to study the developmental sequence o" the mandibular teeth as the teeth structure helps to understand the feeding habits of t lese stages.

The status and validity of the species of Temora recorded rom the Indian Ocean are also discussed. The present study as well as the previous distrib ational records provide evidence to the inference that Temora stylifera (Dana) and T. discaudata Giesbrecht are allopatric, with the former restricted in distribution to the Atlantic and its adjacent seas and the latter to the Indo-Pacific.
