In Jainism, ekendriya jiv are:

• One‑sensed living beings
• They have only the sense of touch (sparsh‑indriya).

They are also called sthāvar jiv (immobile beings). Jain scriptures describe five main types of ekendriya jiv:

1. Prithvi‑kaya – earth‑bodied beings

(living forms in natural earth, clay, stones, metals, etc.)

1. Ap‑kaya – water‑bodied beings

(living forms in natural water)

1. Tejas‑kaya – fire‑bodied beings

(living forms in natural fire/heat)

1. Vayu‑kaya – air‑bodied beings

(living forms in natural air)

1. Vanaspati‑kaya – plant‑bodied beings

(all plants, seeds, creepers, trees, etc.)

For ahimsa, Jains are taught to be very careful even with these very minute lives – in soil, water, air, fire, and plants.
