Pachyzoidae is a little-known family of deep-sea ctenostome Bryozoa that until now was monospecific for Pachyzoon atlanticum. Originally described from the Atlantic Ocean, the genus was also found off southeastern New Caledonia in deep wate...

Ctenophora is the earliest metazoan taxon with neurons and muscles. Recent studies have described genetic, physiological, and cellular characteristics of the neural and muscular systems of this phylogenically important lineage. However, des...
Epimorphic development in tropical shallow-water Nymphonidae (Arthropoda: Pycnogonida) revealed by fluorescence imaging [0.03%]
荧光成像揭示的热带浅水Nymphonidae类（节肢动物：Pycnogonida）的端生发育现象

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 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

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
