Few animal groups can claim the level of wonder that cephalopods instill in minds researchers and general public. Much cephalopod biology, however, remains unexplored: largest invertebrate brain, difficult husbandry conditions, complex (meta-)genomes, among many other things, have hindered progress addressing key questions. However, recent technological advancements sequencing, imaging, genetic manipulation opened new avenues for exploring biology these extraordinary animals. The molecular...
Volvox rousseletii is a dioecious species belonging to sect. that has previously only been found in Africa. During field surveys large dam lake (Lake Sagami) Kanagawa Prefecture, central Japan, we encountered produces sexual spheroids the water column. Although induction of this culture did not produce adequately well-developed for identification, molecular data directly obtained from field-collected verified identity male and female as well cultured materials. Based on morphological data,...
AbstractMorphologies of animal appendages are highly diversified depending on lifestyles. In cephalopods (Mollusca, Cephalopoda), an individual possesses multiple arms that contribute to elaborate behaviors, and suckers them enable various arm functions. octopus hatchlings, sucker morphologies can be divided into two different types due alternative posthatching lifestyles, is, pelagic or benthic although the underlying developmental differences have yet elucidated. this study, therefore,...
Cephalopods have acquired numerous novelties and expanded their habitats to various marine environments as highly agile predators. Among cephalopod novelties, multiple arms are used for complex behaviors, including prey capture. Suckers on innovative features realizing these arm functions. In addition, tentacles in Decapodiformes (squids cuttlefishes) specialized capture tentacular suckers show unique morphologies. However, little is known about the developmental process of sucker formation...
Abstract Background : Morphological novelties have been acquired through evolutionary processes in relation to the acquisition of new life-history strategies together with novel functions bodyparts. Cephalopod molluscs such as octopuses, squids and cuttlefishes possess morphological characteristics their overall bodyplans numerous arms. Among those morphologies, particular, suckers arranged along oral side each arm multiple functions, capturing prey locomotion, so that sucker morphology is...
Abstract Background : Morphological novelties have been acquired through evolutionary processes and related to the adaptation of new life-history strategies with functions bodyparts. Cephalopod molluscs such as octopuses, squids cuttlefishes possess unique morphological characteristics. Among those novel morphologies, in particular, suckers arranged along oral side each arm multiple functions, capturing prey locomotion, so that sucker morphology is diversified among species, depending on...
Various lineages of arthropods have colonized land during evolution, and each lineage has independently acquired air-breathing organs. Some taxa oniscidean isopods (Crustacea, Isopoda, Oniscidea), one the most successful crustacean on land, possess organs called “lungs” in their abdominal appendages, i.e., pleopods. Although these lungs are thought to be an important innovation for adaptation terrestrial environments, lung formation process yet elucidated. In this study, therefore, focusing...
