First record of the glass octopus Vitreledonella richardi (Cephalopoda: Vitreledonellidae) from the Arabian Sea

Abstract

Background: Arabian Sea considered as one of the richest region of oceanic cephalopods. On conflicting information related to species diversity is still scare.

New record of Abralia (Heterabralia) siedleckyi Lipinski, 1983 (Cephalopoda: Enoploteuthidae) from south-eastern Arabian Sea with some remarks about its biology

“…Silas (1968) reported occurrence of A. andamanica from Arabian Sea throughout the year except January, September and October. Recently some new sighting records of deep-sea cephalopods have been reported from the south-eastern Arabian Sea (Rithin et al, 2015, Sajikumar et al, 2016.…”

Mated Shiny bird squid, Ornithoteuthis volatilis Sasaki, 1915 (Cephalopoda: Ommastrephidae), in the southeastern Arabian Sea

“…The Indian Ocean cephalopod fauna is still poorly described and nothing is known about the biology of various species (Paitkowski and Welsch, 1991) and is by far not as well investigated as that of the Pacific and Atlantic Oceans (Nesis, Silas (1968), Silas et al (1985), Aravindakshan and Sakthivel (1973), Piatkowski and Welsch (1991), Joseph et al (2015), Sajikumar et al (2016Sajikumar et al ( , 2017Sajikumar et al ( , 2018Sajikumar et al ( , 2023, Venkatesan et al (2023). However, all previous Indian studies fail to record the species from the Arabian Sea.…”

“…In the last few decades, studies on the distribution and abundance of oceanic cephalopods from the Indian Ocean are scarce, and only limited studies have been documented from the Arabian Sea. However, recent advances in the knowledge of the diversity of cephalopods (Sreeja, 2013;Joseph et al, 2015;Sajikumar et al, 2016Sajikumar et al, , 2017Sajikumar et al, , 2018Sajikumar et al, , 2023Venkatesan et al, 2023) of India argue for more comprehensive studies.…”

Rediscovery of Ram’s horn squid, Spirula spirula (Cephalopoda: Spirulidae), from the Arabian Se

“…Oceanic cephalopods of the Arabian Sea are poorly understood (Piatkowski and Welsch, 1991). Although in recent years detailed studies were conducted on the taxonomy and systematics of cephalopods from the Arabian Sea (Sreeja et al, 2015;Sajikumar et al, 2016Sajikumar et al, , 2017Sajikumar et al, , 2018 and researchers emphasised the need for more studies on cephalopod diversity from seas around India. Our objective was to understand the distribution and abundance of deep-sea cephalopods in the eastern Arabian Sea, and in this work, we report the presence of the uncommon cephalopod from the oceanic waters of the Arabian Sea.…”
