Distinguishing between Stage I and Stage II nauplii of the copepods Metridia and Pseudocalanus from the Bering Sea

Stage I nauplii of Metridia pacifica , Stage I and II nauplii of Metridia lucens , and the equivalent stages of Pseudocalanus mimus were reared from eggs to find morphological characters for separating the genera at these stages. Differences in naupliar body shape and caudal armature permit the diff...

Description
Summary:Stage I nauplii of Metridia pacifica , Stage I and II nauplii of Metridia lucens , and the equivalent stages of Pseudocalanus mimus were reared from eggs to find morphological characters for separating the genera at these stages. Differences in naupliar body shape and caudal armature permit the differentiation of Stage I and II Metridia from Pseudocalanus in southeastern Bering Sea plankton.
