These sea beasts look terrifying with their pointed snouts, large eyes, streamlined bodies and a greyish-brown colour. The Spurdogs' venom can cause extreme discomfort and swell in humans.

Though it might not be much comfort, you can also find non-venomous Starry Smoothhounds and Tope sharks in the Thames.

Wave hello next time you see a seal

A whopping 4000 seals live in the Thames and its estuary. The main species are harbour and grey seals, often seen on the sandbanks and coastal creeks. They feed on fish and crustaceans and are considered top predators in the country. Grey seals travel as far as 100km to look for food. No wonder there are sightings of them following the fish as far up as central London.

The Thames was incredibly polluted and declared ‘biologically dead’ 60 years ago. Today the river and its banks are home to over 125 species of fish and more than 92 species of birds, including the grey heron. Thames wildlife gets more diverse day by day. The frequent sightings of animals not seen before, such as otters or even whales, mean that the improvements in the city's infrastructure and conservation programs are a success.
