研究者发现幽灵鲨鱼的额头上有牙类结构 有助于交配 Researchers discover ghost sharks have tooth-like structures on their foreheads to aid in mating.

研究者发现, 幽灵鲨鱼, 或黑猩猩, 长出专业化的牙齿 在前额的附加物上 被称为护身符 帮助抓住雌性在交配中。 Researchers found that ghost sharks, or chimaeras, grow specialized teeth on a forehead appendage called the tenaculum to help grasp females during mating. 这些牙齿在基因上与口中的牙齿相似, 而不是鲨鱼的皮肤内核, 显示出进化在重新规划结构中的适应性。 These teeth are genetically similar to those in the mouth, not to shark skin denticles, showing evolution's adaptability in repurposing structures. 这项研究利用CT扫描和遗传分析,突显了海洋隐藏的生物多样性。 The study, using CT scans and genetic analysis, highlights the ocean's hidden biodiversity.
