Global biogeography of marine tintinnids

Abstract

Distributions at the genus level reveals several distinct biogeographic patterns: cosmopolitan, neritic, warm-water, boreal, and austral. Some of the factors that may account for these patterns are examined. At the species level, certain disjunct distributions are examined, including the bipolar distribution of Acanthostomella norvegica and the interoceanic distributions of tropical tintinnids, Endemicism of species within certain genera, such as Codonellopsis, was also found. -from Authors
