Chittagong Croton

The Chittagong Croton (Croton chittagongensis) is a Critically Endangered plant species in the family Euphorbiaceae, named for the Chittagong region of southeastern Bangladesh where it was first documented. The genus Croton is one of the largest in flowering plants, containing over 1,200 species of trees, shrubs, and herbs distributed across tropical and subtropical regions worldwide. Members typically produce alternate leaves that are often covered in stellate (star-shaped) hairs, and small unisexual flowers arranged in racemes or spikes. Like many Croton species, C. chittagongensis may produce aromatic oils or latex in its tissues. The critically endangered status of this species reflects the catastrophic scale of deforestation in the Chittagong Hill Tracts and surrounding lowland forests of Bangladesh, where remaining natural forest cover has been severely fragmented. The Chittagong region historically supported rich mixed-deciduous and semi-evergreen forest, but decades of agricultural expansion, fuelwood extraction, and urban growth have reduced forest extent dramatically. With an extremely restricted known range and severely degraded habitat, this species faces genuine risk of extinction without targeted conservation intervention. Formal population surveys, ex situ seed banking, and habitat protection or restoration efforts within the remaining forests of the Chittagong Hill Tracts and adjacent Myanmar border areas are urgently needed.

koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.
