Behavioral responses of larvae of the crab Neopanope sayi to hydrostatic pressure

Abstract

ABSTFWCT Responses of Stages I and IV zoeae of the crab Neopanope sayi (Smith) to changes in hydrostatic pressure were s t u d e d using a closed circuit video system to describe the behavior underlying depth regulation. This species occurs as an adult in estuaries but larvae develop in lower estuarine and coastal areas. Larval responses changed little throughout zoeal development.
