Abstract Bobtail squid are emerging models for host–microbe interactions, behavior, and development, yet their species diversity distribution remain poorly characterized. Here, we combine mitochondrial transcriptome sequences with morphological analysis to describe three of bobtail (Sepiolidae: Sepiolinae) from the Ryukyu archipelago, compare them related taxa. One Ryukyuan type was previously unknown, is described here as Euprymna brenneri sp. nov. Another morphologically indistinguishable...
Abstract The origin and dispersal of cultivated wild mandarin related citrus are poorly understood. Here, comparative genome analysis 69 new east Asian genomes other mainland reveals a previously unrecognized sexual species native to the Ryukyu Islands: C. ryukyuensis sp. nov. taxonomic complexity mandarins then collapses satisfying simplicity, accounting for tachibana, shiikuwasha, traditional Ryukyuan types as homoploid hybrid formed by combining with various mandarins. These reproduce...
Abstract Although the camera-type eyes of cephalopods and vertebrates are a canonical example convergent morphological evolution, cellular molecular mechanisms underlying this convergence remain obscure. We used genomics single cell transcriptomics to study these in visual system bobtail squid Euprymna berryi , an emerging cephalopod model. Analysis 98,537 transcriptomes from nervous identified dozens types that cannot be placed simple correspondence with those vertebrate or fly systems, as...
Bobtail and bottletail squid are small cephalopods with striking anti-predatory defensive mechanisms, bioluminescence, complex morphology; that inhabit nektobenthic pelagic environments around the world's oceans. Yet, evolution diversification of these animals remain unclear. Here, we used shallow genome sequencing thirty-two bobtail squids to estimate their evolutionary relationships divergence time. Our phylogenetic analyses show each Sepiadariidae, Sepiolidae, three subfamilies Sepiolidae...
Cephalopod research remains limited by the inability to culture species under laboratory conditions for multiple generations provide continuous access animals at all stages of life cycle. Here, we describe a multi-generational system two emerging cephalopod models: hummingbird or Berry’s bobtail squid, Euprymna berryi Sasaki, 1929, and Morse’s morsei Verrill, 1881, which are primarily found off mainland Japan. E. wild adults were spawned raised third filial generation, second generation in...
Animals adopt various forms of hunting according to their ecological, morphological, and cognitive features, specific skills are acquired ontogenetically in relation these features. It is noted that cuttlefish squid hunt prey through the elongation tentacles used specifically capture prey. However, two cephalopods have different lifestyles, leading questions such as whether skill similarly after birth tentacle behaviorally identical. To address questions, we observed compared how captive...
Cephalopod have large brain, lens eyes and numerous chromatophore. They accomplish observational learning with this information processing system. In spite of sharing the well-developed system, there are big variations for their cognitive ability among octopus squid. Solitary benthic should good spatial cognition long arms. On other hand, gregarious nektonic squid communication school members. Although knowledge about inter-individual relationship squids will help deep understanding...
