Today, we’re going to learn about some really cool and unique animals. Let’s dive into the world of the axolotl, the aye-aye, and the blobfish. Get ready for some fun facts and exciting discoveries!
Have you ever heard of an axolotl? It’s not a lizard or a fish, but a special kind of amphibian called a salamander. Unlike most salamanders, axolotls live their whole lives in water. They are often called “Mexican walking fish” because they keep their gills and look like tadpoles even when they grow up.
Axolotls are meat-eaters, or carnivores. They love munching on worms, insects, small fish, and crustaceans. They used to be at the top of their food chain, but now other fish like perch and tilapia have moved in.
Did you know axolotls can regrow parts of their bodies? If they lose a leg, they can grow it back! They can even fix parts of their brain if they get hurt. Sadly, axolotls are endangered in the wild, but they are doing well in places where people take care of them.
Next up is the aye-aye, the world’s largest night-time primate. These animals are about 16 inches long and have dark fur that helps them hide in the forest. They have big eyes and ears to help them see and hear in the dark.
Aye-ayes have a special thin finger they use to find food. They tap on trees to listen for insects inside. When they find some, they use their finger to pull them out. They also use their strong teeth to open hard fruits and nuts.
Aye-ayes walk in a funny way because they lift their clawed fingers to keep them safe. Their name might come from the sounds they make when they’re scared. Aye-ayes help forests grow by spreading seeds and eating insects that could harm trees.
Finally, let’s meet the blobfish. These fish live deep in the ocean, where they look like regular fish. But when they’re out of water, they look a bit strange. Blobfish don’t have muscles and float because they’re made of a jelly-like substance.
Blobfish are like the “sloths of the sea.” They stay still and wait for food to come to them. When something tasty floats by, they open their mouths and gobble it up!
Blobfish don’t have many predators because they live so deep in the ocean. They spend their lives relaxing on the sea floor. Even though they lay lots of eggs, only a few survive to grow up. Blobfish help keep the ocean clean by eating dead plants and animals.
Let’s see what you’ve learned! Why are axolotls no longer at the top of the food chain? It’s because of invasive species. Which word best describes these animals? If you said “unique,” you’re right! And do blobfish have many predators? Nope, that’s false!
Great job learning about these fascinating creatures! If you enjoyed this, check out more fun lessons at learn.org. Keep exploring and discovering new things!
Axolotl Observation Journal: Create your own axolotl observation journal! Draw a picture of an axolotl and write down what you think it would be like to have one as a pet. What would you feed it? How would you take care of it? Share your journal with your family and discuss why axolotls are endangered and how people can help protect them.
Aye-Aye Finger Hunt: Pretend you are an aye-aye and go on a “finger hunt” around your home or garden. Use your finger to tap on different surfaces and listen carefully. Imagine what it would be like to find food this way. Discuss with a friend or family member how the aye-aye’s special finger helps it survive in the wild.
Blobfish Float Experiment: Try a fun experiment to understand how blobfish float. Fill a bowl with water and gather objects like a sponge, a small rock, and a piece of plastic. Predict which items will float or sink. Place them in the water and observe what happens. Talk about how the blobfish’s jelly-like body helps it float in the deep ocean.

Hello, animal lovers! Today, we are going to learn about some unique animals. If you want to follow along with us, head over to learn.org to download this lesson plan.
Let’s start off with our friend, the axolotl. What is an axolotl? Is it a lizard? Is it a fish? An axolotl is one of the most unique amphibians in the world. It is a type of salamander, but unlike other salamanders, axolotls spend their entire lives in the water. They are often referred to as Mexican walking fish because of a rare condition called neoteny. The adult axolotl remains aquatic and retains its gills instead of going through a normal amphibian life cycle. As a result, the adults keep the features of tadpoles, with feathery gills and long dorsal fins.
What do axolotls eat? Axolotls are carnivores; they primarily eat worms, insects, crustaceans, and small fish. Axolotls were at the top of the food chain in their environment for a long time, but with the introduction of invasive species like perch and tilapia, they are no longer at the top.
Other interesting facts: Axolotls can regenerate almost any of their body parts. For example, if the leg of an axolotl is wounded or cut off, it will form a blood clot and regrow a new leg. Scientists have also found that axolotls can even regenerate part of their brain if it gets damaged.
Why are axolotls essential to the environment? Sadly, axolotls are critically endangered, meaning their numbers are in sharp decline, and there is a real threat that they may become extinct. However, this only applies to wild axolotls; they thrive in captivity, so there are now more axolotls in captivity than in the wild.
Next, what is an aye-aye? The aye-aye is the world’s largest nocturnal primate. It spends 80% of the night foraging for food. Aye-ayes are about 16 inches long and have coarse dark brown or black fur, which acts as camouflage in the dense forest. They have bulging eyes, large ears, and a bushy tail. Their large ears help them listen for the movement of grubs and larvae to eat, and their large eyes have a reflective layer on the back to improve their night vision. Aye-ayes have teeth like rodents; their incisors grow perpetually, which means they never stop growing throughout their lives. They use their incisors to burrow through hard bark, exposing grubs and insect larvae. Aye-ayes also use their teeth to pry open hard shells of coconuts and other fruits and nuts.
What do aye-ayes eat? Aye-ayes have a unique thin middle finger that they use to find food. For example, they tap on trees and carefully listen for the hollow sound of grubs inside the wood. When they hear the right sound, they create a small hole in the tree and then insert their specialized finger to extract the insects. They also use this middle finger to dig the pulp out of fruit.
Other interesting facts: When moving on the ground, aye-ayes raise their clawed fingers to avoid damaging them. Because of this, they have a strange, clumsy gait. People think the name “aye-aye” comes from their high-pitched vocalization when fleeing danger. Aye-ayes were originally classified as rodents because their incisors grow perpetually.
Why are aye-ayes important to the environment? Aye-ayes help disperse fruit tree seeds throughout their territory, which helps regenerate forests. They are also important because they eat wood-boring beetle larvae, which could overtake the woods without a natural predator.
Now, what is a blobfish? Outside of the water, blobfish can look quite strange, but they resemble regular fish in the ocean’s depths at 2,000 to 3,900 feet below. However, a blobfish is much different from typical fish. It does not use a gas bladder like other fish to create buoyancy. A blobfish can float like a balloon because it is made up of a gelatinous mass with a lower density than water. The blobfish also lacks any muscle.
What do blobfish eat? Since blobfish remain almost entirely still, they have been called the “sloth of the sea.” They are often referred to as “lying-in-wait predators,” meaning the blobfish will hang around with its mouth open and wait for anything edible to float into its jaws, then suck it in.
Other interesting facts: The blobfish has no natural predators because they live so far down in the ocean that the water pressure is too intense for most predators. They can spend their entire life peacefully sitting on the sea floor, and humans don’t eat them either. Chefs don’t like to cook blobfish because they lack muscles and bones like other fish, and the gelatinous flesh isn’t easy to cook. However, those who have eaten them say they taste like lobster.
Why are blobfish important to the environment? Blobfish are an endangered species. Even though these fish lay thousands of eggs, only a few of their young survive to adulthood. This low survival rate, combined with overfishing and deep-sea trawling, has caused the blobfish population to decline quickly. Nevertheless, blobfish are essential because they are bottom feeders and help balance the plant matter and mesopelagic population.
Wow! We have learned some cool facts about some strange animals. Let’s review: Why are axolotls no longer at the top of the food chain? Because of invasive species.
Choose the word that best describes these three animals: A) defenseless B) venomous C) unique D) endangered predator. If you said C) unique, you are correct!
True or false: Blobfish have many predators. If you said false, that’s correct!
