Hey there! Squeaks and I were watching some cool videos of people throwing boomerangs. A boomerang is a special toy that, if thrown just right, comes back to you! We learned that boomerangs come from Australia, and we thought it would be fun to try one out ourselves.
While thinking about boomerangs, we remembered an animal called Diplocaulus, which lived over 250 million years ago, even before dinosaurs! Diplocaulus had a head shaped like a boomerang. It was an amphibian, which means it could live both in water and on land, just like frogs and salamanders today.
Amphibians usually start their lives in water, hatching from eggs and breathing through gills. As they grow, they develop lungs to breathe air and can live on land. Diplocaulus likely lived in or near water, similar to modern amphibians.
Scientists study fossils, which are remains of ancient animals, to learn about creatures like Diplocaulus. By comparing fossils to living animals, they discovered that Diplocaulus had a long, flat body similar to alligators and salamanders, suggesting it was a good swimmer.
Some scientists thought its boomerang-shaped head made it hard for predators to eat, but evidence showed that predators like Dimetrodon could still bite it. Others believe the head shape helped Diplocaulus swim fast, like how airplane wings lift planes into the air.
After learning about Diplocaulus, Squeaks and I talked about another interesting amphibian called the axolotl. Axolotls are special because they live underwater their entire lives and have gills that look like feathers on their heads.
Unlike most salamanders, axolotls don’t lose their gills as they grow. They can also regrow body parts like legs and even their heart! Axolotls come in various colors, including pink, which makes them look unique and fun.
Axolotls are native to only one lake in the world, Lake Xochimilco in Mexico. They face many dangers in the wild due to habitat changes. Keeping an axolotl as a pet is challenging because they need specific conditions to thrive, and it’s important to protect their natural habitat.
Next, we explored the world of poison dart frogs, known for their bright colors and patterns. These frogs use their colors to warn predators that they are poisonous. Some indigenous people have even used their poison for hunting.
Poison dart frogs get their poison from the insects they eat, like ants and beetles. In captivity, without these insects, they can lose their poison over time.
Some non-poisonous animals mimic the bright colors of poison dart frogs to trick predators into thinking they are dangerous too. This is called mimicry. For example, the mimic poison frog looks like its poisonous relatives, even though it isn’t as dangerous.
We also learned about snakes that use mimicry. The harmless scarlet kingsnake looks similar to the dangerous coral snake, making predators think twice before attacking.
