Cylisticus convexus

A species of terrestrial isopod belonging to the family Cylisticidae. It is commonly known as the curly woodlouse due to its ability to curl its body into a loose defensive shape when threatened, though not as completely as true pill bugs.

Native to Europe but now introduced to many other regions, it is a hardy and adaptable species often found in gardens, forests, urban habitats, and agricultural environments.

Scientific classification: Family Cylisticidae, order Isopoda.

Habitat: Moist terrestrial habitats including leaf litter, compost, under stones, bark, rotting wood, and garden debris. It tolerates a wider range of conditions than many delicate woodland isopods.

Typical size: 1–1.8 cm (0.4–0.7 in) in length.

Distribution: Originally Europe, now widespread across North America and other temperate regions through accidental introduction.

Diet: Detritivore feeding on decaying plant matter, fungi, dead organic material, and decomposing wood. It contributes to nutrient recycling in soil ecosystems and is especially successful in disturbed habitats due to its adaptability and resistance to environmental fluctuations.

Philoscia affinis

A species of terrestrial isopod belonging to the family Philosciidae. It is a slender, fast-moving woodlouse known for its agility compared to more heavily armored or slow species.

Native to Europe, it is commonly found in moist woodland environments where it moves quickly through leaf litter and vegetation rather than relying on heavy defensive curling.

Scientific classification: Family Philosciidae, order Isopoda.

Habitat: Damp terrestrial habitats such as forests, grasslands, gardens, and areas rich in leaf litter. It tends to prefer slightly more open and active microhabitats than strongly cryptic woodlice.

Typical size: 8–12 mm (0.3–0.5 in) in length.

Distribution: Europe, especially central and western regions, with some spread into adjacent areas.

A species of parasitic marine isopod belonging to the family Cymothoidae. It is infamous for attaching itself to the tongues of fish, where it survives by feeding on blood and mucus before functioning as a replacement tongue.

Native to warm marine waters, it is one of the most unusual known parasitic crustaceans and is widely studied for its bizarre host relationship.

Scientific classification: Family Cymothoidae, order Isopoda.

Habitat: Coastal marine environments, living inside the mouths of fish hosts.

Typical size: Up to 3 cm (1.2 in) in length.

Distribution: Eastern Pacific Ocean, especially around the Gulf of California and coastal regions of Latin America.

A species of coastal isopod belonging to the family Ligiidae. Often called the sea slater, it is considered one of the more primitive forms of isopod and acts as a link between fully marine and terrestrial species.

Native to rocky shorelines of northern Europe, it is highly adapted to life in the harsh intertidal zone where waves, salt spray, and changing tides constantly reshape the environment.

Scientific classification: Family Ligiidae, order Isopoda.

Habitat: Rocky coasts, tidal zones, sea cliffs, and crevices near the ocean shoreline.

Typical size: Up to 3 cm (1.2 in) in length.

Distribution: Northeastern Atlantic coasts, including the shores of United Kingdom, Ireland, and Scandinavia.
