Habitat & Geographic Range
Christmas Cactus
Typically found in diverse terrestrial habitats from tropical forests to temperate regions.
Found in Brazil. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
Delfín tonina
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 12 distinct biome types. Populations are also found in montane and highland environments at higher elevations.
Widely distributed across Asia (Taiwan), Europe (6 countries), and South America (Colombia, Ecuador, Venezuela).
Christmas Cactus
The Christmas cactus (Schlumbergera opuntioides) is a species of epiphytic cactus in the family Cactaceae, native to the Atlantic Forest region of southeastern Brazil. It is notably distinct among Schlumbergera species in having more cylindrical stem segments that bear small spine-bearing areoles, giving it a superficial resemblance to opuntia cacti and accounting for its specific epithet. Most other species in the genus have flattened, segmented phylloclades largely lacking true spines. Schlumbergera opuntioides grows in humid montane forests as an epiphyte, anchored to tree branches or rock faces. Its flowers are tubular and zygomorphic, attracting hummingbird pollinators. The species has a more restricted distribution than some better-known relatives and is found at moderate elevations within its Atlantic Forest range. Habitat loss is the principal threat to all Brazilian Schlumbergera species, as the Atlantic Forest biome has been massively reduced through centuries of human activity. Schlumbergera opuntioides is of considerable interest to cactus taxonomists due to its morphological distinctiveness within the genus and has contributed to scientific understanding of evolutionary relationships within Schlumbergera.
Delfín tonina
La especie de delfín más estudiada y reconocida, los delfines mulares habitan océanos cálidos y templados de todo el mundo, desde las aguas costeras poco profundas hasta el mar abierto. Altamente inteligentes con grandes cerebros en relación con el tamaño corporal, demuestran autoreconocimiento, comunicación compleja y aprendizaje social. Viven en sociedades fluidas de fisión-fusión y cooperan para arrear peces. Una especie indicadora clave de la salud del ecosistema marino.
