More than 30 Aesculapian snakes are living on the banks of Regent's Canal. The snake may have not been identified due similarity with green snake. It was only after the head keeper of reptiles at London Zoo saw one and identified it as Aesculapian snake.

There are many theories as how Aesculapian snakes came into the wild. One of the rumors suggests that these snakes escaped from London Zoo and since then, they have been living in the wild in the Camden area.

Another rumor stated that these snakes, which are counted as Europe's third largest, were released in the wild as a part of scientific experiment by the Inner London Education Authority.

The snakes have been found eating large rats and birds. London Invasive Species Initiative (LISI) manager, Karen Harper said, "Aesculapian snakes species is listed in the Wildlife and Countryside Act 1981 meaning it is illegal to allow the species to spread or escape into the wild".

For now, not much is known as how the species would affect the local ecosystems. Now, it is suggested that these snakes can be culled, but nothing is finalized for now. Ecologists were of the view that there should be a 'justification of resources' in culling the animals.

But other say steps are needed as the snakes may start entering houses. There is a greater concern for parents who think if these snakes can crush small animals then they may do the same to young children.

Aesculupian snake is an eight-foot reptile that prefers to stay in areas having mild temperature along river beds like Regent's Canal. Though these snakes are poisonous, they are capable of killing small dogs, rodents and birds.
