## Traits

- [Shade Tolerant](https://www.snappit.app/explore/traits/shade-tolerant): Shade tolerant plants are adapted to grow and thrive in areas with low light levels, requiring less direct sunlight.
- [Coniferous](https://www.snappit.app/explore/traits/coniferous): Coniferous plants are typically evergreen, bearing needles or scales and reproductive cones.
- [Evergreen](https://www.snappit.app/explore/traits/evergreen): Evergreen plants retain their foliage throughout the year, never shedding all their leaves at once.
- [Ancient Lineage](https://www.snappit.app/explore/traits/ancient-lineage): This trait signifies organisms belonging to a very old evolutionary group with ancestors dating back millions of years.
- [Forest](https://www.snappit.app/explore/traits/forest): Forest habitats are terrestrial environments dominated by dense tree cover, supporting a high diversity of plant and animal life.
- [Longevous](https://www.snappit.app/explore/traits/longevous): This trait characterizes organisms with an exceptionally long lifespan compared to others of their kind.
- [Toxic](https://www.snappit.app/explore/traits/toxic): Toxic organisms contain substances that are poisonous and can cause adverse effects upon exposure.
