Weāre living in a world devoid of ancient horrors that haunted prehistoric people, and while it may be true to some point (T-Rex is gone for sure), there are still some creatures left around that havenāt changed much since they first appeared millions of years ago. Most of these creatures look so god-damned frightening as if Mother Nature has completely forgotten about their existence. Here are some weird creatures that havenāt changed much for the last few millions of years.
Ever wondered what kinds of animals have been walking the Earth before the dinosaurs first appeared? Well, this is what some of them looked like. These incredible survivors are 540 million years old and have successfully outlived some of the more menacing and aggressive species. Maybe it was the fierce-looking shell that has protected them for millions of years, or maybe it were the 5 pairs of eyes they have. Two of them you can actually see poking from the shell. Horseshoe crabs are related to the more ancient trilobites that once inhabited our planet. Their blood is even used for testing vaccines and drugs.
Giant Squid
While scientists are still not sure as to the age of this species (it might very well turn out to be a more āmodernā animal), this Giant Squid surely looks like it belongs in the prehistoric era. Caught in the waters of Antarctica, this huge animal weighed 770 pounds and was as long as a huge bus. Colossal squid sightings are something you only read about in books or hear from salty mariners, but here it is ā the stuff of legends!
Nautilus
Only 6 species of Nautilus remain today, out of hundreds that used to inhabit the oceans. Nautilus has an incredible shell that works as a submarine and has chambers that can be filled with water or gas when the creature needs to go deeper or ascend. Apart from ādrivingā the very first āsubmarineā thatās ever been invented, these creatures havenāt really changed at all during the past 500 million years or so.
Tuatara
Tuatara is probably the closest thing to dinosaurs you can still see roaming the Earth. Scientists sometimes refer to them as āliving dinosaursā because of their similarity to the giant lizards that once populated our planet. Being almost 220 million years old, they really havenāt changed much during the course of history. This un-evolved species can be found in a number of islands around New Zealand and sometimes on the mainland as well.
Tadpole Shrimp
You donāt need to know the exact age of tadpole shrimps to see that these creatures are prehistoric. They just have this weird āancientā look that canāt be confused with something else. Tadpole shrimps (also called āshieldā shrimps because of their look) develop quickly from an egg into an adult and it takes them mere three weeks to grow up. Itās easy to see how theyāve survived for 250 million years, outliving dinosaurs and other big prehistoric creatures.
Coelacanth
This menacing species of fish was recently re-discovered in 1938. Scientists believed they have gone extinct along with the dinosaurs millions of years ago, but these creatures re-emerged on the coasts of South Africa, proving they were still pretty much alive and kicking. Just like most of prehistoric animals that can be found today, Coelacanths havenāt changed much and bear great likeness to the fossils that are 350 million years old.
