More than 4,000 different species of jellyfish have been identified, many of which have been around for 500 million years.

Other invertebrates have existed for at least 500 million years. There are already more than 4,000 species of these organisms in the oceans across the world.
These are not fish, despite the word “fish” appearing in their name. Like virtually all fish, and don’t have gills, scales, fins, or backbones. Sometimes congregate in enormous clusters known as blooms.

In the past, sure Southeast Asians consumed crabs often.

Over the last several decades, their appeal in cuisine has declined. The fact that these creatures are utilized as bait has significantly decreased their population in specific locations.

The coelacanth is a little-known fish that has existed for 410 million years and dwells at depths of around 2,300.

Fish with lobed bodies, known as coelacanths, have existed for around 410 million years. They are deepwater fish that live 2,300 feet below the surface of the ocean. One of the oldest instances of a fish with a jaw is this one.
They have tiny brains occupying only 1.5% of their cranial cavity, with fat occupying the remaining 95%. After believing this species had gone extinct millions of years before, it recovered in 1938.

These fishes reside close to the ocean floor. They descend far into the water and may survive between 600 and 5,000 feet below the surface.

Elephant nose fish, or the Australian ghost shark, has been around for over 400 million years. Although they share a cartilaginous structure with sharks and are closely related to them, they are not sharks. They are lonely creatures that spend their days searching the ocean bottom for tiny food, including shrimp, mollusks, and other shellfish.

They occupy a transitional space between modern lizard characteristics and those of dinosaurs. They are neither a lizard nor a dinosaur and have distinct ancestry.
Because they provide information on the evolution of lizards and snakes, scientists are interested in them. They are the planet’s last of their type. They have a lengthy lifespan and often pass away around age 60.

Gharials swallow their prey whole rather than chewing it despite having numerous sharp teeth.

Since 200 million years ago, gharials have lived in the slow, muddy rivers of the Indian subcontinent. Tiny northern India and Nepal are included in the drastically restricted range. They risk becoming extinct since probably less than 100 survive in the wild.

They only come to the beach to nest and sunbathe since they spend most of their time in the water. They are unable to control their body temperatures. Thus, they must sunbathe or cool down in the water, depending on the weather.

Even though they cannot eat, these reptiles have over 100 sharp teeth. They clamp down on food with their formidable teeth before devouring it whole.

The sturgeon fish has been around for 100 million years and may be in fresh and saltwater. The Northern Hemisphere’s temperate zones are home to more than 25 distinct kinds.

It is used to produce some of the greatest caviar in the world, but doing so has placed certain species in danger of extinction. Even though they have few predators due to their size, lampreys utilize them as their blood-feeding supply. Most giant sturgeons weigh well over a thousand pounds.
