Background: Extant lineages of sea spiders (Pycnogonida) exhibit different types of development. Most commonly, pycnogonids hatch as a minute, feeding protonymphon larva with subsequent anamorphic development. However, es...
Color vision evolution in egg-laying mammals: insights from visual photoreceptors and daily activities of Australian echidnas [0.03%]
产卵哺乳动物的颜色视觉进化：从澳洲鸭嘴兽的视觉感光细胞和日常活动中得到的启示
Shiina Sakamoto,Yuka Matsushita,Akihiro Itoigawa et al.
Shiina Sakamoto et al.
Egg-laying mammals (monotremes) are considered "primitive" due to traits such as oviparity, cloaca, and incomplete homeothermy, all of which they share with reptiles. Two groups of monotremes, the terrestrial echidna (Tachyglossidae) and se...
Comparative analysis of Hmx expression and the distribution of neuronal somata in the trigeminal ganglion in lamprey and shark: insights into the homology of the trigeminal nerve branches and the evolutionary origin of the vertebrate jaw [0.03%]
七鳃鳗和鲨鱼三叉神经节中Hmx表达及神经元胞体分布的比较分析：对脊椎动物颌的起源以及三叉神经分支同源性的新认识
Motoki Tamura,Ryota Ishikawa,Yuki Nakanishi et al.
Motoki Tamura et al.
The evolutionary origin of the jaw remains one of the most enigmatic events in vertebrate evolution. The trigeminal nerve is a key component for understanding jaw evolution, as it plays a crucial role as a sensorimotor interface for the eff...
Homology of the head sensory structures between Heterotardigrada and Eutardigrada supported in a new species of water bear (Ramazzottiidae: Ramazzottius) [0.03%]
水熊虫新物种（Ramazzottius，Ramazzottiidae）支持了Heterotardigrada和Eutardigrada头部感觉结构的同源性

Ji-Hoon Kihm et al.
Phylum Tardigrada is represented by microscopic eight-legged panarthropods that inhabit terrestrial and marine environments. Although tardigrades are emerging model animals for areas of research including physiology, evolutionary biology, a...
A review of the genus Muusoctopus (Cephalopoda: Octopoda) from Arctic waters [0.03%]
北极海域穆氏章鱼属（cephalopoda: octopoda）一览

Alexey V Golikov et al.
We report two Arctic species of incirrate octopods new to science. One is formally described here as Muusoctopus aegir Golikov, Gudmundsson & Sabirov sp. nov. while the other, Muusoctopus sp. 1, is not formally described due to a limited nu...
Cell type specific polyploidization in the royal fat body of termite queens [0.03%]
散金蜂宫腔细胞多倍体现在白蚁后群中的特异性分布

Tomonari Nozaki
Tissue-specific endopolyploidy is widespread among plants and animals and its role in organ development and function has long been investigated. In insects, the fat body cells of sexually mature females produce substantial amounts of egg yo...
Male spiny frogs enter the underwater battlefield with loose skin exhibiting enhanced penetration of capillaries into the epidermis [0.03%]
雄毛脚蛙通过皮肤变脆进入水下战场：皮下血管扩张导致表皮易刺穿
Shuang Xu,Qiang Dai,Yuchi Zheng
Shuang Xu
The skin has multiple functions, and capillaries can penetrate the epidermis to shorten the diffusion path while allowing maintenance of overall epidermal thickness for nonrespiratory roles. However, a method for quantifying the capillary p...
Difference in sulfur regulation mechanism between tube-dwelling and free-moving polychaetes sympatrically inhabiting deep-sea hydrothermal chimneys [0.03%]
同域分布的深海热液环境中栖管与自由移动环节蠕虫硫调节机制差异性研究
Tomoko Koito,Yusuke Ito,Akihiko Suzuki et al.
Tomoko Koito et al.
The environment around deep sea hydrothermal vents is characterized by an abundance of sulfur compounds, including toxic hydrogen sulfide. However, numerous communities of various invertebrates are found in it. It is suggested that inverteb...
