Habitat & Geographic Range

Cultivated Mushroom

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Distributed across Austria, Belgium, Norway, and Sweden.

Green Sea Turtle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 8 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Australia, Brazil, Costa Rica, Indonesia, and Mexico. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Cultivated Mushroom

The most widely cultivated mushroom globally, the button mushroom in its various growth stages — white button, cremini, and portobello — accounts for approximately 40% of world mushroom production. Domesticated from wild Agaricus species found in grasslands across Europe and North America, they are grown commercially in controlled environments on composted straw and manure. Rich in B vitamins, selenium, and dietary fiber, they are one of the most nutritionally versatile fungi in human cuisine.

Green Sea Turtle

The green sea turtle is one of the largest sea turtles. They are named for the green color of their cartilage and fat, not their shells.
