An Octopus briareus specimen was recorded off Port Sisal, Yucatán, Mexico. This finding represents the first record of O. briareus in the southern Gulf of Mexico, expanding the currently known westernmost distribution area for this species on the American continent. The specimen was captured by scientific divers performing routine maintenance at underwater facilities in the area of the discovery. The collected specimen was an adult female weighing 25.3 g. The presence of O. briareus could be related to changes in the environmental conditions in the Caribbean Sea and the Gulf of Mexico.

“…The blue-lined octopus Hapalochlaena cf. fasciata is a small octopus that has been reported to be distributed in Australia, Korea, and Japan [ 15 , 16 , 17 , 18 ]. The blue-ringed octopus contains TTX throughout the body, including the posterior salivary glands (PSGs), gonads, and arms, with the PSGs being the most highly toxic organ [ 15 , 19 , 20 ].…”

The xanhid crab Atergatis floridus and the blue-lined octopus Hapalochlaena cf. fasciata have long been known as TTX-bearing organisms. It has been speculated that the TTX possessed by both organisms is exogenously toxic through the food chain, since they are reported to have geographic and individual differences. The source and supply chain of TTX for both of these organisms, however, remain unclear. On the other hand, since crabs are one of the preferred prey of octopuses, we focused our attention on the relationship between the two species living in the same site. The aim of this study was to determine TTX concentrations and TTX profiles of A. floridus and H. cf. fasciata, collected simultaneously in the same site, and examine the relationship between them. Although there were individual differences in the TTX concentration in both A. floridus and H. cf. fasciata, the toxin components commonly contained 11-norTTX-6(S)-ol in addition to TTX as the major components, with 4-epiTTX, 11-deoxyTTX, and 4,9-anhydroTTX as the minor components. The results suggest that octopuses and crabs in this site acquire TTX from common prey, including TTX-producing bacteria and/or may have a predator–prey relationship.

“…Among them, the shallow-water benthic octopus Hapalochlaena fasciata, which is also called as the blue-lined octopus, is most commonly found around intertidal rocky shores and coastal waters between Australia and the Pacific Ocean north to Japan (Williamson et al 1996;Kohtsuka 2006;Kim et al 2012). In Korea, the appearance of H. fasciata is increasing every year (Kim et al 2018), but there are very little scientific records. In this study, we reported the complete mitochondrial genome (mitogenome) of the highly venomous blue-lined octopus, H. fasciata from the southern coastal waters, Korea.…”

The complete mitochondrial genome of the highly venomous blue-lined octopus, Hapalochlaena fasciata (Hoyle, 1886), was analyzed by the primer walking method. Its mitogenome was 15,479 bp in total length, comprising 13 protein-coding genes, 2 ribosomal RNA genes, and 23 transfer RNA genes. In the phylogenetic tree, the gene content and order were congruent with those of typical octopodiform species. The mitogenomic sequence presented could be very useful as the first record of the complete mitogenome for the genus Hapalochlaena.
