Which animal is known as the ''living dinosaur''?

The animal known as the 'living dinosaur' is the crocodile. These reptiles have been around for over 200 million years, and their physical appearance has remained relatively unchanged since the time of the dinosaurs. Crocodiles are often referred to as 'living fossils' because they are the closest living relatives to the ancient reptiles that roamed the earth during the Mesozoic Era.

Crocodiles can be found in a variety of habitats, including rivers, lakes, and swamps. They are known for their powerful jaws and sharp teeth, which they use to catch their prey. Crocodiles are also excellent swimmers and can hold their breath underwater for up to an hour.

Despite their prehistoric appearance, crocodiles are an important part of many modern ecosystems. They help to keep populations of fish and other aquatic animals in check, and their habitats provide important nesting sites for many bird species.

There are several animals that are commonly referred to as "living dinosaurs". These include:

• Crocodiles. Crocodiles are large, ancient reptiles that have changed very little over the past 200 million years. They are closely related to dinosaurs, and share many of their features, such as a long tail, powerful jaws, and scaly skin.
• Tuatara. Tuatara are small, lizard-like reptiles that are found only in New Zealand. They are the only living members of an ancient group of reptiles that were once widespread, but went extinct everywhere else on Earth. Tuatara have many features that are similar to dinosaurs, such as a spiky crest on their back and a long tail.
• Horseshoe crabs. Horseshoe crabs are marine arthropods that have been around for over 450 million years. They are closely related to spiders and scorpions, but they have some features that are similar to dinosaurs, such as a hard exoskeleton and a segmented body.
• Axolotl. Axolotls are amphibians that are native to Mexico. They have a unique appearance that has earned them the nickname "walking fish". Axolotls have feathery gills, a long tail, and a wide head. They are also able to regenerate limbs and organs, which is a feature that is shared by some dinosaurs.

These are just a few of the animals that are sometimes called "living dinosaurs". These animals are all fascinating creatures that offer a glimpse into the past.
