The Diet of the Texas Tortoise

What do Texas Tortoise eat​?

Texas tortoises are omnivores, and their diet includes a range of plants and small invertebrates. Here are the most common foods in their natural diet:

Plants and Grasses:

  • Dandelions (Taraxacum officinale): Rich in vitamins A and C, and calcium. These are commonly available in spring and summer.

  • Clover (Trifolium spp.): High in protein and minerals. It grows abundantly during spring and early summer.

  • Alfalfa (Medicago sativa): Contains essential vitamins and minerals. Found year-round in many habitats.

Cacti and Succulents:

  • Prickly Pear (Opuntia spp.): Texas tortoises eat both the pads (nopales) and the fruits (tunas). They are high in water content, vitamins A and C, and calcium. The spines of the nopales are typically avoided or removed by the tortoises before consumption. These are available mainly in late summer and early fall.

  • Other Succulents: Various species that provide hydration and nutrients like calcium and magnesium.

Flowers and Fruits:

  • Wildflowers: Such as bluebonnets (Lupinus texensis) and Indian paintbrushes (Castilleja indivisa), which bloom in spring and early summer.

Invertebrates:

  • Insects: Such as beetles and ants, providing a good source of protein.

  • Small Invertebrates: Including earthworms and snails, which are available year-round, especially after rain.
