Life Cycle of the Red-Eared Turtle

Red-eared sliders are hardy turtles found near ponds and streams throughout the United States. These turtles eat both plant and animal matter. They are considered semiaquatic, as they live both in and out of the water.

  1. Breeding

    • Red-eared sliders (RESs) breed through sexual reproduction. The female makes a nest and may lay up to 20 eggs at at time.

    Eggs

    • Once laid in the nest of dry soil, RES eggs need temperatures between 81 and 86 degrees Fahrenheit. Eggs hatch within 60 to 80 days, at which point the hatchling turtle breaks free of the eggshell.

    Hatchlings

    • Hatchlings usually emerge in late summer or early fall, but may remain in the warm nest through winter. These tiny turtles are mostly carnivorous, eating worms, insects and minnows. Due to their small size, they are very susceptible to predators and disease.

    Adults

    • Adult RESs grow to be between seven and12 inches in length (seven to nine inches for males; nine to 12 for females). RESs reach sexual maturity at age two to four years for males and three to five years for females. Adult RESs consume more plant matter than animal matter.

    Lifespan

    • RESs have a long lifespan both in the wild and in captivity. In the wild an RES may live up to 20 years or more, while in captivity an RES may live 40 years or more.
