Terrifying Creature Spotted in River That Has Everyone Questioning What It Is

While this creature looks like something straight out of a graphic horror movie, the species is one that dates back 340 million years ago and sparks fascination among those lucky enough to spot it. Craig Evans has been guiding tours in South West Wales for seven years now and he recently shared a picture of the mysterious fish on his Instagram page, which quickly garnered attention.

From its many-toothed mouth to its eel like texture, this species is certainly one worth taking note of – especially if you ever come across one in British rivers.

The sea lamprey is a jawless fish belonging to the Petromyzontidae family which can grow up to two feet long. They are also known as ‘vampire fish’ due to their parasitic behavior and ability to suck the blood from larger fish with ease.

Despite their intimidating appearance, they lead short existences spawning in May or June before dying soon after – usually days later. The creatures can only swim in fast-flowing waters with no barriers and otters are the only animals that will eat them – and even then they only dare to munch on the last few inches of its tail.

Sea lampreys are most commonly found along the shores of North America, Europe, and in the Great Lakes region but thanks to Evans’ expert knowledge on what lives around Welsh coastlines (and his faithful dog Llew) people have become more aware of these ancient species being found closer than expected.

While some may find them terrifyingly fascinating others may be hesitant about trying out their ‘weak watery flesh’ as suggested by Evans himself.

Despite how creepy they may appear at first glance sea lampreys actually help maintain healthy eco-systems by providing food for other aquatic life forms such as salmonids and sturgeon whilst aiding oxygen levels within waterways – making them an important part of our environment despite not being particularly attractive.

In some parts of the world such as Portugal, they are even considered delicacies due to their unique texture so don’t forget that next time you stumble across one during your fishing trips.
