15 Ancient Creatures That Are Still Alive
The animals we see around us are only 10 percent of all species that have ever lived on earth. Of these animals, some have survived the various shifts of earth’s geology through evolutionary adaptation and managed to survive extinction for millions of years. You won’t believe how long some creatures have been roaming the earth, but you will find when you join us now and watch 15 Ancient Creatures that are still alive. So, climb into your time machine and get ready for some fascinating stuff.

SANDHILL CRANE
Found in Siberia and parts of North America, Sandhill cranes are believed to have been in existence for 10 million years, as can be understood from their structural similarity with a fossil dating back to the Miocene epoch some 10 million years ago. Whether stepping singly across a wet meadow or filling the sky by the hundreds and thousands, Sandhill Cranes have an elegance that draws attention. These tall, gray-bodied, crimson-capped birds breed in open wetlands, fields, and prairies across North America. They group together in great numbers, filling the air with distinctive rolling cries. Mates display to each other with exuberant dances that retain a gangly grace.
Sandhill Crane populations are generally strong, but isolated populations in Mississippi and Cuba are endangered. Sandhill Cranes are large birds that live in open habitats, so they’re fairly easy to spot if you go to the right places. Sandhill Cranes are known for their dancing skills. Courting cranes stretch their wings, pump their heads, bow, and leap into the air in a graceful and energetic dance
Frilled Shark
This shark species has hardly changed in appearance in the 80 million years of its existence, earning it the epithet of “living fossils.” A deep-sea creature, this rarely spotted shark has 300 needle-shaped teeth. Frilled sharks are active predators and may lunge at potential prey, swallowing it whole, even if it is quite large. Their normal swimming style, however, is distinctly eel-like, as they swim in a serpentine fashion. The preferred prey of the frilled shark is squid, and they have several rows of long teeth, each with three long points, that are perfect for snagging the soft bodies of this prey. Though they specialize in squids, frilled sharks are known to eat a variety of fishes and other sharks. Frilled sharks are only very rarely encountered in the wild, so little is known about their ecology. The limited information that scientists do have is based on the dissection of individuals captured in Deepsea net fisheries and observation of the occasional live individual in captivity.
Frilled sharks reproduce via internal fertilization and give live birth. However, they do not connect to their young through a placenta, like in most mammals. Instead, embryos live off of energy obtained from yolk sacs, and only after the juveniles are able to survive on their own does the mother give birth to her young. Little is known about the population trends of frilled sharks, but they are rarely encountered by humans and are likely naturally rare.
