Hello, friends! Today, we’re going to learn about some amazing animals called vertebrates. Do you know what makes them special?
Vertebrates are animals that have a backbone or spine. This backbone helps them move and keeps their bodies strong. There are five main groups of vertebrates: mammals, birds, fish, amphibians, and reptiles.
Mammals are animals that are born from their mothers. They drink milk from their mothers when they are babies. Mammals have teeth to chew their food, breathe with lungs, and are warm-blooded, which means they keep the same body temperature. Most mammals have hair or fur, and they can live on land, in water, or even fly!
Fun Facts: The blue whale is the biggest mammal and can be as long as a basketball court! Horses have teeth that never stop growing. And guess what? Humans are mammals too!
Birds are born from eggs. They have two legs and wings, which help most of them fly. Birds have light bones because they are hollow, and they breathe with lungs. They eat with their beaks and have feathers covering their bodies.
Fun Facts: The ostrich is the heaviest bird, and eagles are birds that can fly high in the sky!
Fish live in water and are born from eggs. They have fins and tails to help them swim. Fish have scales on their bodies and breathe through gills. They are cold-blooded, which means their body temperature changes with the water.
Fun Facts: Some fish, like salmon, can swim from the ocean to rivers!
Amphibians are born from eggs in water. They start life breathing with gills, but as they grow, they can live on land and breathe with lungs and through their skin. Amphibians have moist skin and are cold-blooded.
Fun Facts: Amphibians are the only vertebrates that change from having a tail to having legs as they grow, a process called metamorphosis!
Reptiles are born from eggs and have hard scales on their bodies. Some, like snakes, have no legs, while others, like turtles, have shells. Reptiles are cold-blooded and breathe with lungs. They usually live in warm places.
Fun Facts: Some turtles can live for over a hundred years!
Invertebrates are animals without a backbone. Some have hard outer shells for protection. There are six groups of invertebrates: mollusks, worms, arthropods, cnidarians, echinoderms, and sponges.
Arthropods have an exoskeleton, a hard outer shell, and jointed legs. They can live on land, in water, and some can even fly.
Fun Facts: Arthropods are the largest animal group, with over 10 million types! Some ants can lift 100 times their weight!
Mollusks have soft bodies, and some have shells. They are born from eggs and include snails, clams, and squids.
Fun Facts: Some squids can grow as tall as a five-story building!
Worms have long, soft bodies and breathe through their skin. They crawl using muscles and tiny bristles.
Fun Facts: The longest worm ever found was 180 feet long!
Cnidarians live in the sea and include jellyfish and polyps. Jellyfish have tentacles with stingers, while polyps attach to rocks.
Echinoderms live in the sea and move slowly. This group includes starfish, sea urchins, and sea cucumbers.
Fun Facts: If a starfish loses a leg, it can grow a new one!
Sponges live in the sea and have bodies full of tiny holes. They can’t swim and feed on small particles in the water.
That’s all about vertebrates and invertebrates! Thanks for learning with me today!

Backyard Safari: Go on a backyard safari to find examples of vertebrates and invertebrates. Take a notebook and draw or write down the animals you see. Look for birds, insects, worms, or even pets! Discuss with a friend or family member which animals have backbones and which do not. What makes them different? Can you find examples of each group mentioned in the article?
Animal Charades: Play a game of animal charades with your friends or family. Each person takes turns acting out an animal from the vertebrate or invertebrate groups without using words. The others must guess which animal it is and identify if it’s a vertebrate or invertebrate. After each round, share a fun fact about the animal you acted out!
Create a Creature: Use clay, playdough, or craft materials to create your own imaginary animal. Decide if your creature is a vertebrate or an invertebrate. Does it have a backbone or an exoskeleton? What group does it belong to? Present your creature to the class or family and explain its features and how it fits into the animal kingdom.

Hello, friends! Today we will talk about vertebrate animals. Do you know which ones they are?
[Music]
Vertebrates are animals that have an articulated internal skeleton. This skeleton supports the body and allows them to move. Vertebrates are classified into five groups: mammals, birds, fish, amphibians, and reptiles.
Today, I will focus on mammals. Mammals are viviparous animals, meaning they are born from their mother’s womb. Mothers have mammary glands that provide milk to feed their young. Inside their mouths, they have teeth to chew their food.
[Music]
Mammals breathe through their lungs and are warm-blooded. Most of them have hair covering their bodies, and they can live on land, in water, and some can even fly.
Here are some fun facts about mammals: The biggest mammal is the blue whale, which can measure up to 30 meters long, a little more than a basketball court. Horses are another type of mammal, and their teeth do not stop growing throughout their lives. And yes, humans are also mammals!
Now, let’s learn about another group of vertebrate animals: birds.
[Music]
Birds are oviparous animals, which means they are born from eggs. They walk on two legs and have two wings that allow them to fly, although some birds, like ostriches and penguins, do not fly despite having wings. Birds have a lightweight skeleton because their bones are hollow. They breathe through their lungs and are warm-blooded. Birds eat with their beaks, which do not have teeth, and their bodies are covered in feathers.
Did you know that the heaviest bird in the world is the ostrich? And the eagle is a bird that can fly.
Next, we will discuss fish.
[Music]
Fish are aquatic animals that can live in fresh or salt water. They are oviparous, meaning they are born from eggs. Fish have fins to move in the water and a tail that helps them swim easily. Their bodies are covered in scales, and they breathe through gills. Fish are cold-blooded, meaning their body temperature varies with the water temperature, and they have a simpler skeleton than other vertebrates.
Did you know that some fish, like salmon and eels, travel from saltwater to freshwater?
Now, let’s talk about amphibians.
[Music]
Amphibians are oviparous animals, which means they are born from eggs. The babies are born in water and breathe through gills. As they grow, they can live on land or in water and breathe through their lungs and skin. Amphibians have moist skin and do not need hair. They are cold-blooded, meaning their body temperature varies with the air temperature.
Did you know that amphibians are the only vertebrates that are born with a tail and live in water? As they grow, they develop four legs and live on land. This change is known as metamorphosis.
Now, let’s learn about reptiles.
[Music]
Reptiles are oviparous animals, meaning they are born from eggs. Their bodies are covered in hard scales, and some reptiles, like snakes, do not have legs. Some reptiles have shells, like turtles. They are cold-blooded, meaning their body temperature varies with the air temperature, and they breathe through their lungs. Reptiles usually live in warm places. Did you know that some reptiles, like turtles, can live for over a hundred years?
Now, let’s move on to invertebrate animals.
Invertebrates do not have a backbone or skeleton. Some invertebrate animals have hard outer shells for protection. Invertebrates fall into six groups: mollusks, worms, arthropods, cnidarians, echinoderms, and sponges.
Let’s start with arthropods.
[Music]
Arthropods are very diverse but share common features. They have an external skeleton called an exoskeleton, which protects the soft parts of their bodies. Some arthropods shed their exoskeletons several times throughout their lives, a process known as molting. Arthropods have jointed legs and can live on land, in water, and even fly.
Did you know that arthropods are the largest group in the animal kingdom, with more than 10 million different types? Some ants can lift 100 times their body weight!
Next, let’s discuss mollusks.
[Music]
Mollusks have soft bodies, and some are protected by shells while others are not. Mollusks are oviparous and are classified into three groups: gastropods, cephalopods, and bivalves. Gastropods, like snails, move using a muscular foot. Bivalves, like clams, have shells that close tightly for protection. Cephalopods, like squids, have long tentacles and live in water.
Did you know that some squids can grow as high as a five-story building?
Now, let’s learn about worms.
Worms have long, soft bodies and moist skin. They breathe through their skin and do not have legs, so they crawl using body muscles and tiny bristles called setae. Worms can live on land, like earthworms, or in water, like leeches. Earthworms are important for soil health as they help aerate the soil and transport nutrients.
Did you know that the largest worm ever found measured 180 feet long?
Next, we will talk about cnidarians.
Cnidarians are marine animals divided into two groups: jellyfish and polyp animals. Jellyfish have gelatinous bodies and tentacles with toxic substances for capturing prey. Polyps attach themselves to rocks and have tentacles and a mouth for feeding.
Finally, let’s discuss echinoderms.
Echinoderms are exclusively marine animals that move slowly on the seabed using tiny tube feet. Starfish, sea urchins, and sea cucumbers belong to this group. Did you know that when a starfish loses a leg, a new one will grow in its place?
Lastly, sponges have bodies full of pores and live in the sea. They cannot swim and were once thought to be plants because they cannot make their own food. Instead, they feed on plankton and tiny particles in the water.
