Speed-Swimming is the ability all mermaids and mermen are shown to have. It is one of the most used ability in Mako Mermaids. It allows them to swim at the speed of 100 - 300+ km/h depending on the mermaids/mermans experience, their top speed is said to be 500 km/h. Their body is encased in bubbles and use it as a jet stream to swim faster and to reduce water pressure. This power is mostly used for racing other merpeople or escaping from boats and other merpeople. It is also used to get somewhere faster if they're upset, angry or are just doing it for fun.
