What is Opabinia?

Opabinia was a truly bizarre and ancient creature that lived hundreds of millions of years ago. It belonged to a group of extinct animals that swam in Earth’s early seas, long before dinosaurs or even fish as we know them today. With its unusual body and strange features, Opabinia stands out as one of the oddest animals ever discovered.

How big was Opabinia?

Opabinia was not very large compared to some prehistoric giants. It grew up to about 7 centimetres (less than 3 inches) long. Despite its small size, it had a striking appearance that set it apart from anything alive today.

What did Opabinia eat?

Opabinia was a carnivore, meaning it ate other animals. Scientists believe it used its long, flexible snout to grab small prey, such as worms or other soft-bodied creatures, from the muddy sea floor. It would then bring the food to its mouth, which was located underneath its head.

Opabinia appearance

Opabinia looked like something from a science fiction film! Its body was soft and segmented, and it had five eyes on top of its head, which helped it spot danger and find food. Its most famous feature was its long, tube-like snout ending in a claw, perfect for reaching into burrows or grabbing prey. On its back, it had flaps that helped it swim through the ancient Cambrian seas.
