Thalia longicauda(Quoy and Gaimard) from the south-western Atlantic Ocean (31°S–38°S): distribution and population structure
Abstract Although the salp Thalia longicauda is common in the southern hemisphere, there is little information on its biology and ecology. Our study aimed to describe the morphology of the development of solitaries and aggregates and to determine the developmental stages, length distribution and pop...

The relationship between total number of aggregate buds (y) and total length of the solitary (x) was y = 3.321x − 13.489. We characterized six developmental stages for solitaries and four for aggregates. The juvenile/mature ratio of solitaries and aggregates suggested that the population was actively reproducing both sexually and asexually. Based on seawater temperature and salinity data, T. longicauda may be considered as a temperate species inhabiting the southern range of subtropical waters and the northern range of sub-Antarctic waters.
