For more than 200 years, there have been reports of a ' monster ' in central Africa in the Ubangi, Sanga and Ikelemba Rivers and Lake Tele. Mokèlé-mbèmbé is the name given to a large creature reported to live in the lakes and swamps of the Congo River basin.it has been suggested that the creature might be a dinosaur such as a brachiosaur or a stegosaur which survived extinction . It may also refer to many different creatures.Several expeditions have been sent into what is now Zaire, with no conclusive photographic or physical evidence . Though the "living dinosaur" theory for Mokele-mbembe might be the best-known explanation, it has seen very little support from mainstream scientists. The latest expeditions to the area were by two Japanese teams in 1978 and 1992 and reported seeing a larged animal. The civil wars in Zaire have cancelled more recent planned expeditions in Zaire and shifted attention to the Cameroon, where the creature is known as la Kela-bembe.  more info

This list of lake and sea monsters is by no means complete. There are many other locations with sightings as well. Some of the more common explanations for monster sightings are : logs, otters (Giant Otters can grow up to 6 ft, the otter in this video appears to be a lake monster at first glance, giant sturgeons,giant catfish, and schools of fish. 


Could some lake and river monsters be plesiosaurs

long necked reptiles that lived during the Mesozoic Era and died out with the dinosaurs and the end of the Cretaceous with the KT mass extinction

65 million years ago ? While they were marine animals, some fossils have been found in what were then rivers .

However, how could a modern day plesiosaur live in northern latitudes such as Loch Ness and Lake Champlain ? It would have to be a mammal. Some suggest it may be a type of  basilosaurus , the elongated snake like ancestor of modern day whales and lived 35-40 million years ago. 

Another explanation for Nessie and other European lake monsters is that people are sighting a large European eel (Anguilla anguilla), which live in Loch Ness in large numbers.  The common European eel grows to a maximum length of about six feet or 1.8 metres in length. These eels are generally believed to spawn in the Sargasso Sea. The larvae  (Leptocephalus) drift towards Europe in a three-hundred-day migration . These eels have the ability to 'walk' on land up to 8 hours.

  Some look for an explanation in our own minds. It is all part of our collective unconscious and as the wave of ufo sightings in the 1950s reflect an underlying fear of the Cold War going hot and a wish for an otherworldly savior, lake monster sighting reflect a deep seated need for a monster to exist.  People expect and want to see them, so they do.

In 1925, legendary explorer Percy Fawcett ventured into uncharted realms of the Amazon jungle in order to discover "The Lost City of Z," an ancient civilization that he believed could have been the basis for the mythical El Dorado. Fawcett and his party disappeared, never to be heard from again. Eighty years later, David Grann, an ordinary reporter for The New Yorker, uncovered Fawcett's diaries and found himself compelled to follow in the footsteps of the intrepid adventurer. An inspiration for The Lost World and Indiana Jones
