Speed-Swimming is the ability that all merpeople are shown to have.
It is one of the most used merperson abilities in H2O: Just Add Water and Mako: Island of Secrets. It allows them to swim at the speed of 600 km/h. Their body is encased in bubbles and use it as a jet stream to swim faster. Zac describes Speed-Swimming as "fly".
This power is mostly used for racing other merpeople or escaping from boats and other merpeople. It's also used to get somewhere faster or if they are upset or angry.
Siren Singing is a musical/voice-related magical ability that allows the user to put a person (usually a man) into an irresistible, hypnotic trance in which he will follow the mermaid around or obey the mermaid's whim and desires without question.
In this trance, the person does whatever they are told. In myths, sirens would sing their hypnotic tunes to attract and lure sailors to their deaths under the seas. The mermaids in the pod made the Enchantment Song strictly forbidden. However, Rita mentioned that sometimes when sailors or humans accidentally saw a mermaid, they need to be drowned and killed to preserve the secret, but since the Mako pod forbid the Enchantment Song, they drown them by making a storm. In other mermaid pods however, it is unknown whether they allow the Enchantment Song to drown sailors.
The only way to reverse the Enchantment Song is to blow into a particular seashell.
When a mermaid used the Siren Song during the Full Moon effect, then the songs are reversed only when the full moon sets.
