A systematic account of the chaetognatha of the Indian coastal waters, with observations on their seasonal fluctuations along the Malabar Coast. [PDF]

open access: yes, 1952
Material for this investigation was collected mainly from the triweekly plankton hauls from the foreshore and offshore waters, off West Hill, three miles north of Calicut in the Malabar District along the West Coast of India (750 46' E. and 110 17' N.)

Predation Strategies of the Portuguese Man‐of‐War Physalia physalis

open access: yesMarine Ecology, Volume 46, Issue 6, November/December 2025.
ABSTRACT The Portuguese man‐of‐war Physalia physalis is widely known for causing poisoning on human beings. Physalia physalis is mostly described as a predator of fish eggs and larvae. Here, we report for the first time that large fish can also be preyed by P. physalis.

Chaetognath community structure in the coastal Central Mexican Pacific: persistent seasonal signals amid ENSO variability (2010–2016)

open access: yesDiscover Oceans
Chaetognaths are abundant carnivorous zooplankters that play a pivotal role in structuring and regulating the pelagic ecosystem, yet long-term studies of their ecological dynamics in the Mexican Pacific are limited.

Chaetognaths (Chaetognatha: Sagittoidea) at the Boundary of the Pacific Ocean and the Gulf of California: Their Relationship with the Summer Circulation Pattern

open access: yesOceans
Chaetognaths play an essential role in zooplankton communities and significantly contribute to their overall biomass. Changes in the hydrographic properties of the water column, driven by hydrodynamic processes, affect their species richness and ...
