Number three hundred and thirty three, the amazing african lia. Good morning. Or is that good . afternoon? Who can I am lying down anyway? Oh. that was tired. This is the african lion king of the jungle, which is all because they don't live in jungle today. You can find lines in a small thing of india. but state in africa, in a few places. south. T, T, together in big family groups called prides. What's the kids? I'm gonna work. Uh. keep your tail on. Most of the pride is made up of liones. They do most of the hunting line. S is our excEllent stealth predators and very loving mom. when you to a couple porter, definitely your son, stop being. So cat, and what does the male lion do? He has a big Harry main, and that, I guess you could say, I have the raw talent. Yes, the law is very important, warning of other lions in their territory. And IT keeps everyone together. Where did everybody go? Did you know that lions . love fast food? The fires? They might be big for ocean ous push cat predators, but the african lion is undoubtedly an amazing animal. octopus. Optimistic have elaborate cardiovascular and nervous systems. The cardiovascular system includes three hearts to pump blood to the girls, and a third moves blood through out the rest of the body. Unlike human blood, octopus blood is copper based, which makes IT appear blue. The optimist nervous system includes a brain, but two thirds of the optimists neurons are found throughout its body, specially in its arms. This means the arms have significant local control and sensory capabilities. They may even still reach or grasp after they are severed, and their suckers are able to sense chemicals, in other words, smell or taste. Optimists are intelligent. Some scientists, the optimist intellect, can be found in their ability to use tools and exhibit foresight to retain complex memories, which helps them navigate mazes and solve puzzles, and to use visual cues, which helps them differentiate between human individuals. Octopuses have also been shown to play an activity considered a sign of intelligence. Most optimistic species only live between one and two years. Much of this short lifespan has to do with the octopus es reproduction process. When octopuses made, males may be strangled and eaten by females, males are often smaller than females, so they become overpowered and sometimes canabal. Zed, one's fertilization is complete. While females survive the mating process. They die after laying their eggs. Female octopuses got their eggs for up to eight weeks. During this time, the female's boys self destruct through cellular suicide until he dies. Octopus ink is deadly. Even for the octopus, the ink is a seemingly innocent mixture of mucus and melanin. Melanin, the same dark pigment found in skin, hair and eyes, also happens to contain the chemical compound to rosini, which can impair a predator site, taste and smell. Optimistic and other suffer apods may use their aim to distract, confuse and paralyzed their predators. This muk, this mixture, may even block of fishes gills, causing the fish to suffocate. If an octopus cannot escape its own ink, its respiratory ory systems may be compromised, causing the octopus s to suffocate and die. Octopuses are masters of mimicry and camouflage. They can trigger cells just underneath the services of their skin to change color. The cells, called creative phs, contain sex of pig men that can turn various shades within milliseconds. Some octopuses, such as the common octopus, can also imitate textures that can warp small segments of their skin, called a pilly. To match textured environments, species like the mimic optimus are able to not only cambodge themselves, but also manipulate the shape of their bodies to impersonate other animals. Their widely mimicry, along with many other curious characteristics, are just a few reasons why octopuses are captivating creatures of the deep. 大家好，今天我们要一起学习关于章鱼的一切。如果你对这种神奇的动物感兴趣，那快来跟我一起看一下。什么是章鱼？章鱼是一种非常酷的海洋生物，属于软体动物类。它们的身体很柔软，没有骨头，因此非常灵活。因为没有坚硬的骨骼，章鱼可以轻松挤过狭小的空间，就像海底的杂技演员一样，他们的身体可以弯曲和拉伸。章鱼的大脑有许多神经细胞，这些细胞分布在身体各处，帮助他们解决各种问题。更酷的是，章鱼有八只手臂，每只手臂上都有吸盘，这些吸盘能够感知化学物质、触觉和刺激。章鱼生活在海洋中，喜欢藏身于有岩石和隐藏处的地方，你可以在全球范围内的潜水和深海中找到它们。有些章鱼喜欢住在洞穴里，而有些则在开放区域生活。章鱼是独居动物，通常喜欢独自生活，但当食物充足或在繁殖季节，他们也会聚集在一起。章鱼照顾幼崽的方式很独特，在产卵后母章鱼会守护着它们，并不断轻轻的吹水来保持它们的氧气供给。在这段时间，母章鱼不吃东西，表现出对幼崽的极大奉献。当幼崽孵化后，他们就得自己开始独自在广阔的海洋中生活。章鱼吃什么？章鱼的食物很丰富。他们的胃口也很好。他们喜欢吃螃蟹和龙虾，还爱吃小鱼，用敏捷的手臂和吸盘迅速捕捉猎物。有些章鱼甚至喜欢吃蛤蜊和蜗牛，大多数章鱼都是夜间捕猎者，并且他们都有毒液，能通过类似描绘的嘴注射到猎物体内。章鱼用他们强大的吸盘紧紧抓住猎物，而吸盘上的小感应器则像一群侦探一样配合工作。吸盘这样的化学感应器能够检测到水中的化学物质，帮助章鱼找到猎物。当章鱼感觉到美味的食物靠近时，他的手臂会非常灵活的移动。触感感应器可以帮助章鱼感觉到物体的质地和形状，就像如果章鱼看到一只螃蟹或虾，他最爱的食物吸盘就会立刻启动，牢牢抓住猎物。章鱼的吸盘和感应器的配合，让它能够迅速准确的捕捉猎物，成为真正的水下捕猎高手。其他有趣的事实。章鱼的皮肤中有一种叫做色素细胞的特殊细胞，这些细胞可以让章鱼改变颜色，形成复杂的图案。这种技能不仅能帮助他们通过伪装躲避捕食者，还能与其他章鱼交流和表达情绪。章鱼是无脊椎动物。中拥有最大大脑的物种之一，非常聪明。他们的脑不仅在头部，还有一部分分布在手臂上，每条手臂里都有许多神经元或小脑细胞帮助章鱼协调动作。章鱼独特的分散式大脑结构让它们能够解决问题，适应不同的环境变化。就像每条手臂都有一个帮助它行动的智囊团，使得他们在面对变化时游刃有余。为了保护自己，章鱼可以使用一种叫做自断手臂的策略。如果遇到危险，章鱼会主动断掉一只手臂，用来转移捕食者的注意力，然后趁机逃脱。更令人惊奇的是，章鱼还能再生新的手臂。为什么章鱼对。生态环境很重要？章鱼在他们的环境中扮演的重要角色，它们帮助控制其他海洋生物的数量，同时也是大型捕食者的重要食物来源。虽然大多数章鱼物种没有濒临灭绝的风险，但污染和过度捕捞可能会影响它们的栖息地，人类也喜欢吃章鱼，因此我们需要确保可持续捕捞。保护他们的栖息环境。哇，我们已经学到了很多关于章鱼的知识，现在让我们来复习一下吧第一题，章鱼为什么会变色？是为了伪装交流和表达情绪。第二题，章鱼是不是所有无脊椎动物中大脑最大的，而且非常聪明？没错，答案是正确的。第三题，你觉得章鱼是怎样的动物？A不灵活的，B脊椎动物，C陆地生物，D濒危的，E独居的。答案是E独居的章鱼专家们干得好。今天我们学到了许多关于章鱼的知识，赶快跟家人或朋友分享一下。如果你对学习其他生物的知识感兴趣，记得关注我。下次见。 INTERNATIONAL DAYOF THE SEAL Reading plus Unit 1 Animal Friends Why are animals important? 阿黎老师原创课件,请勿侵权！微Alilaoshi68 小红书号：阿黎老师小助手 抖音号：阿黎老师3 节日介绍 01 海豹知识 02 海豹知识 03 Learning Objectives 了解大自然中令人惊叹的动物和大自然的奇妙，认识到保护动物和保护大自然的重要性。（迁移创新） 通过本节课的学习，了解章鱼的身体和能力，同时了解介绍类说明文的特征。（学习理解） 通过阅读拓展文章，快速获取文章主旨大意；运用略读寻读阅读技巧，获取文章细节信息；能够根据所给信息，提取和整合文章中的关键信息, 并复述文章和描述其他令人惊异的动物。（应用实践） Wonderful Journey of the Ocean 海洋奇妙之旅 Boys and girls, welcome to our wonderful journey of the ocean!
