Presence of the Wondrous Jewel Squid Histioteuthis miranda (Cephalopoda: Histioteuthidae) in the Eastern Arabian Sea and Determination of its Age from Statoliths

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

“…Recent studies highlight the need of dedicated research to improve knowledge of oceanic cephalopods of Arabian Sea and Indian EEZ (Sajikumar et al, 2018). Abralia siedleckyi is a poorly known species and Hidaka and Kubodera (2000) recommend further investigation to understand the range and distribution for the species.…”

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

“…Following this, Bruun (1943) studied the distribution and biology of the species from Indo-Pacific waters. Recent investigations for understanding cephalopod distribution in the Arabian Sea failed to record this species (Silas, 1968;Aravindakshan and Sakthivel, 1973;Piatkowski and Welsch, 1991;Sajikumar et al, 2017Sajikumar et al, , 2018. The specimens of this species are rare due to their deep-dwelling habits and small size.…”

“…Compared to other seas, the studies on the cephalopod diversity of the Arabian Sea are few and need a comprehensive investigation for a better understanding of the distribution and status (Sajikumar et al, 2018). Much earlier, Chun (1910) reported the Spirula sp.…”

“…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.…”

Mated Shiny bird squid, Ornithoteuthis volatilis Sasaki, 1915 (Cephalopoda: Ommastrephidae), in the southeastern 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.…”
