Zoogeographical aspects of decapod crustacea in the Indian River region of Florida [abstract]

Because of both freshwater runoff and oceanic water input the decapod crustacean fauna in the Indian River consists of freshwater, estuarine and strictly marine forms. A one year survey of this fauna in the river and adjacent shallow Atlantic waters produced over 150 species, roughly divided into three groups: 1) species primarily tropical in affinity and occurring most abundantly in the Antillean province; 2) species of .both tropical and warm-temperate affinity, occurring in both the Antillean and Carolinian faunal provinces; and 3) species whose range extends beyond both the Carolinian province northward, and the Antillean province southward.
