Mitochondrial genomes of four pelagic Chaetognaths Zonosagitta bedoti, Zonosagitta pulchra, Ferosagitta robusta, and Aidanosagitta regularis and the phylogenetic relationships on Sagittiae

open access: yesMitochondrial DNA. Part B. Resources, 2019
Chaetognaths possess simplified body plan that puzzled their morphological phylogenetic classification. Three complete mitochondrial genomes were determined for Zonosagitta bedoti, Z.

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.)

Benthic Environmental DNA Metabarcoding Reveals the Response Mechanism of Metazoan Communities to Artificial Reef Habitats

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
Our study used benthic eDNA metabarcoding to assess metazoan biodiversity, community structure, and network stability in shallow and deep artificial reefs across seasons. Results revealed distinct spatial and seasonal patterns in diversity and co‐occurrence networks, with environmental factors like temperature, nitrite, and DO driving community ...

Distribution, abundance and biomass of Chaetognaths off São Sebastião region, Brazil in February 1994

open access: yesBrazilian Journal of Oceanography, 2002
The distribution, abundance, biomass, population structure and feeding habits of chaetognaths collected off São Sebastião region, Brazil, in February 1994 are described. Bongo nets were hauled obliquely to collect zooplankton samples. Forty-three samples

Trophic interactions of chaetognaths, larval fish, and zooplankton in the South Atlantic Bight

open access: yesOceanographic Literature Review, 1997
Chaetognaths are highly abundant carnivores in manne environments, and feed both on flsh larvae and on the same foods as flsh larvae We assessed predation by chaetognaths on wlnterspawned flsh larvae and on the planktonic food of fish larvae in February ...

Distribution and abundance of zooplankton in the northern Arabian Sea with reference to oil spill in the Gulf waters [PDF]

open access: yes, 1996
Zooplankton of the northern Arabian Sea between lat. 16° and 23°N and long. 62° and 73°E was studied in March, 1991 for understanding the impact on zooplankton, of the large scale oil slick occurred in the Gulf waters during the Gulf War in January ...

The plankton of the tropical western Indian Ocean as a biomass indirectly supporting surface tunas (yellowfin, Thunnus albacares and skipjack, Katsuwonus pelamis) [PDF]

open access: yes, 1994
The biomass of available forage is a key factor in controlling the abundance and distribution of surface tropical tunas, as they have high energy demands and live in a poor environment.

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.
