The southern black racer will eat just about any prey that it can subdue including insects, rodents, frogs and lizards. Occasionally these large nonvenomous snakes will also eat birds and other snakes when they get the chance.
The southern black racer or Coluber constrictor priapus is one of the most frequently spotted snakes in Florida because it is active during the day and is also relatively large for a snake. On average, southern black racers grow to about 5 feet long but can grow to a length of over 6 feet. This snake gets its name from its sleek, black color and its swift movements.
Its scientific name gives rise to the misconception that these snakes constrict their prey. However, southern black racers just subdue their prey with their size and strength, then eat them alive. These snakes are aggressive and will charge at humans in an attempt to scare them. Despite their size and aggressive nature, these snakes are also preyed upon by predatory birds and larger snakes like the black king snake and larger black racers.
