## Appearance

The Riccia is a small, flattened green plant, often forming rosettes or intricate mats on surfaces. Its body, called a thallus, can be bright to dark green and may have tiny air chambers visible on its upper surface, making it look slightly textured. It lacks true stems, leaves, or roots.

## Taxonomy

- **Kingdom:** Plantae
- **Phylum:** Bryophyta
- **Class:** Marchantiopsida
- **Order:** Ricciales
- **Family:** Ricciaceae
- **Genus:** Riccia

## Interesting facts

- It breathes through tiny pores on its surface, like miniature mouths!
- Riccia helps scientists understand Earth's very first land plants from millions of years ago!
- Riccia is a liverwort, named for its liver-like shape! (Ancient people thought it looked like one.)
- Some Riccia species can float and grow entirely underwater in ponds and aquariums!

## Special abilities

- **Direct Sip:** Riccia can absorb water and nutrients directly through its flat body, as it lacks complex roots to do so.
- **Spore Sprinkler:** Riccia has tiny capsules that release spores into the wind or water, helping it spread to new damp places.
- **Fragment Fix:** Riccia can grow new plants from tiny pieces that break off, making it super good at spreading quickly.

## Measurements & details

- **Height:** 0.1-0.5 cm
- **Spread:** 1-10 cm
- **Edible:** No
- **Toxicity:** None
- **Lifecycle:** Perennial

## Ecological connections

- **Eaten by:** [Garden snail](https://www.snappit.app/explore/garden-snail) (*Cornu aspersum*) — Snails graze on Riccia mats.
- **Eaten by:** Great grey slug (*Limax maximus*) — Slugs feed on the soft plant tissues.
- **Symbiotic with:** Nostoc (Cyanobacteria) (*Nostoc commune*) — Often found growing alongside Riccia in wet areas.

## Traits

- [Nonvascular](https://www.snappit.app/explore/traits/nonvascular): This trait characterizes plants lacking specialized vascular tissues (xylem and phloem) for transporting water and nutrients.
- [Spore Producing](https://www.snappit.app/explore/traits/spore-producing): Spore-producing organisms reproduce by releasing small, often single-celled, reproductive units called spores.
- [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.
- [Wetland](https://www.snappit.app/explore/traits/wetland): This habitat trait identifies species found in wetlands, which are areas of land saturated with water, either permanently or seasonally, including marshes, swamps, and bogs.
- [Threatened](https://www.snappit.app/explore/traits/threatened): Threatened status denotes a species likely to become endangered in the foreseeable future without effective conservation interventions.

## Safety

**Danger:** 1/5 · Very low

Enjoy looking at Riccia, but avoid picking or stepping on it to let it grow and help the environment.

## Frequently Asked Questions

1-10 cm

### Is Riccia edible?

No

### Is Riccia toxic?

None

### What is Riccia's lifecycle?

Perennial

### Where is Riccia usually found?

Wetlands
