Ancient animals are a term for animals that lived hundreds to millions of years ago. Due to the constantly changing condition of the planet, many ancient animals were unable to adapt and struggled to survive in the ever-changing conditions of the planet. However, some species of these animals were able to survive and adapt to the changes that occurred on Earth.

"Even some of the following animals have been living for hundreds of years, you know! Here are the oldest living prehistoric animals on earth until now, summarized from various sources, on Wednesday (03/07/2024)."

The following is the translation of the given 'Bahasa' text to 'English' while preserving any html tags: "This ant is blind and likely lives underground or deep within the forest floor litter. Only one individual has ever been found, so their life is still mysterious."

Population of freshwater prawns in the wild is indeed decreasing, but they are resilient and may survive environmental disasters in the future. Their eggs can dry out and become dormant, surviving in poor conditions for years before rehydration and hatching.

Together with hagfish, they are the only jawless fish that still live on Earth. Lampreys are not endangered and are an invasive species that thrives in temperate waters worldwide. They have become a problem in several regions, including the Great Lakes in the United States, as they damage the local ecosystem.

Their lungs are like unique swimming bags that also filter waste and collect oxygen from the air. The anatomy of lungfish is interesting to scientists as an example of animals transitioning from aquatic to terrestrial environments.

This fish is not protected by nerve spines. Instead, they have a notochord that runs along their backbone. This notochord serves as a body support similar to a backbone, considered as a precursor to the evolution of modern backbones.

At present, this species lives scattered in rainforests worldwide as a wandering carnivore, sometimes kept as a pet that feeds on spiders, fleas, and termites, or in captivity, they are given crickets as food.

"They gather on the beach during the mating season in the summer in large groups that reach more than ten thousand individuals per day. Although not closely related to true crabs, they are close relatives of ancient trilobites that once reproduced more than 20,000 species over 3."

The Great Permian Extinction about 250 million years ago significantly affected them, and since then, they have never recovered. Although similar to clams, brachiopods actually do not have a close relationship with them, and they can be found in deep and cold oceans worldwide.

One type of comb jelly that is still alive, Mnemiopsis leidyi, is known to cannibalize its offspring to survive in winter when food sources are scarce in northern waters. The large larvae of these comb jellies survive in the water column after consuming all available prey. This strategy may be the key to the survival of comb jellies for centuries on Earth.

They filter seawater through their porous bodies made of canals. In the past, kitchen sponges were made from this animal, but now they are replaced with synthetic materials for commonly used cleaning sponges.
