Netflix's newest release, Under Paris, has been making waves with its thrilling plot centered around a shark wreaking havoc in the Seine river. It may sound far-fetched, but critics are raving about this film that has been compared to the legendary "Jaws".
According to one review, it is "one of the best shark movies of all time", while another boldly declares it to be "a shark movie worthy of swimming in the wake of 'Jaws'". This high praise is a testament to the film's ability to inject life into a genre that has been lacking in excitement for a long time.
However, one cannot help but question the plausibility of a shark swimming freely in a river that ultimately leads to the sea. Or can they? After all, the Seine does connect to the Atlantic ocean, which is home to great white sharks. And with no walls in the sea, who's to say a shark couldn't make its way into the river?
But before we get carried away with the possibilities, let's consider the fact that there are, in fact, walls in the Seine. These locks act as barriers between the open ocean and Paris, making it nearly impossible for large sea creatures to enter. Ali Hood, director of conservation at the Shark Trust, explains that while some marine wildlife may occasionally wander into these tidal waterways, it is highly unlikely for a shark to make its way into the heart of Paris.
But what about the freshwater found in the Seine? Ali points out that many sharks and rays can thrive in estuarine environments, where the water remains salty. However, they are not equipped to handle the drastic changes in salinity that come with venturing into a river. The lack of adaptation to freshwater would ultimately lead to dehydration, making it difficult for sharks to survive in these environments.
Of course, Hollywood may have us believe that a dehydrated shark would become even more bloodthirsty, but in reality, it is unlikely for a shark to go on a killing spree in freshwater. The last time a large shark was caught in central London was in 1787, and it wasn't in the best condition. However, there are some species of sharks that have evolved to thrive in freshwater habitats.
Ali explains that there are three recognized species of freshwater shark: the Ganges shark, the New Guinea river shark, and the speartooth shark. Additionally, there are reports of unidentified species in Borneo. But the most impressive of all is the bull shark, which is known for its ability to adapt to different environments. This species has been spotted in freshwater rivers and lakes far from the ocean, such as the Mississippi, the Gold Coast in Australia, and even Lake Nicaragua.
Unfortunately, like many other shark species, the bull shark is facing threats from human activities such as habitat loss and overfishing. One-third of all shark and ray species are endangered, including the critically endangered Borneo shark, smalltail shark, and lost shark. These majestic creatures are often caught as bycatch in fishing nets or deliberately targeted for their fins, which are used in shark fin soup.
But there is hope for the future of sharks, as conservation organizations like the Shark Trust are working tirelessly to protect these incredible animals. With over 500 species of sharks and rays, it is important to recognize the vital role they play in our oceans and take action to ensure their survival.
So while a shark swimming through the Seine may not be in the realm of possibility, Under Paris offers a thrilling and sharktastic experience that is sure to entertain audiences. And who knows, maybe one day we will see sharks swimming freely in the city of love. But until then, let's continue to appreciate and protect these fintastic creatures.
