Chaetognatha of the Brazil-Malvinas (Falkland) confluence: distribution and associations
Iheringia: Série Zoologia, 2004 The planktonic chaetognaths from the Brazil-Malvinas (Falkland) confluence, extending between 36º 30' - 50º 5' S and 60º 33' - 41º 7' W, were studied. Ten species were found: Eukrohnia hamata (Möbius, 1875) (Eukrohniidae), Pterosagitta draco (Krohn, 1853)
