Thai waters comprise two tropical zones, Gulf of Thailand, Southwest Pacific Ocean and Andaman Sea, East Indian Ocean. Although the cephalopod fauna from Thai waters was firstly recorded in 1928 but the first taxonomic study covering both zones was in 1974, 48 years later, reporting 5 families, 10 genera and 22 species. At present, 22 families, 36 genera and 81 species are recorded by various authors. One idiosepiid and one sepiolid squids, and three octopods are new to science. Five taxa are considered to be complex species due to difference in morphology and life histories from the literature. The present checklist is the third revision since 1995.

Updated Taxonomic List of Teuthofauna of Thai-Malay Peninsular: Gulf of Thailand and Andaman Sea, In...

July 2016

The teuthofauna of 2 subclass, 8 orders, 32 families, 68 genera and 134 species from Thai-Malay Peninsular are listed in this study. The fauna comprises 67.2% decapods and 32.1% octopods and 0.8% nautiloid. The decapod fauna include 0.8% spirulid squid, 9.7% sepiid cuttlefish, 9.0% sepiolid squids and 2.2% idiosepiid squids, 11.2% myopsid squids and 34.3% oegopsid squids. The group of oceanic ... [Show full abstract] oegopsid squids is the most diverse one and the second rank is the octopods. The percentage of neritic species is 58.2% and of oceanic species is 41.8%. Most of the species, 67.2%, have been recorded from both sides of the Peninsular, 14.2% only in the Gulf of Thailand and 18.6% only in the Andaman Sea. The number of teuthofauna recorded in this region is 87.6% of that reported from the South China Sea. The number of neritic species is also similar indicating the uniformity of ecological conditions throughout the Sunda Shelf. This study also reflects the necessity for taxonomic expertise in the region for this economic group of animal.

New records of the bobtail squid, Euprymna hyllebergi Nateewathana, 1997 with designation of a neoty...

January 2011 · Phuket Marine Biological Center Research Bulletin

A total of 265 specimens, 118 males and 147 females, of the bobtail squid, Euprymna hyllebergi, are registered in the Reference Collection, Phuket Marine Biological Center, Thailand. Nearly all specimens were collected from Thai waters, the Andaman Sea and the Gulf of Thailand. The species is here reported as a new record for Myanmar waters and the distribution in the Indian Ocean has been ... [Show full abstract] extended to the west of the Andaman Islands. A male neotype is designated on a specimen collected from the original locality in order to replace the lost male holotype specimen. The neotype is deposited in the Reference Collection of Phuket Marine Biological Center, Thailand, as is the remaining female paratype, whereas selected specimens are deposited in National Science Museum Tokyo, Japan, U.S. National Museum, Washington D.C., USA and the Zoological Museum, SNM, University of Copenhagen, Denmark. Measurements of the neotype, paratype, and selected specimens are presented and discussed.
