Aggressive sharks on the River Thames – Interesting researchers’ findings in London |

Many species such as sharks, seahorses, eels and seals appear to live in the River Thames, according to a new study published by the BBC.

Scientists from the Zoological Society of London (ZSL) conducted an analysis, which is the most detailed study of the river since the 1950s.

The study aims to capture the changes that have taken place in the bioclimatic level since the river was declared “biologically dead” in 1957.

The report revealed that aggressive shark species live in the 215-mile-long river, including those up to two meters long and those that release venom from their fins, which can cause swelling in humans.

At the same time, more than 115 different species of fish are identified.

Since the 1990s, the river has also grown in its range of birds, marine mammals and natural habitats.

However, the investigation also found that some species of fish living in some parts of the Thames have declined slightly.

Scientists say more research is needed to investigate why this decline occurred.

Climate change is also having an impact on the river as temperatures rise by 0.2 degrees per year, according to the study.

The above leads to an increase in its water level.
