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.

Epaulard

イルカ科で最大の種であるシャチ（Orcinus orca）は体長最大9メートル、体重6トンに達し、北極から南極まですべての海洋に生息しています。独特の方言、狩猟戦略、集団間で異なる文化的伝統を持つ母系ポッドで生活する頂点捕食者です。一部の集団は魚類を、他の集団は海洋哺乳類を専門に捕食します。天敵はなく、シャチは生息するすべての海洋食物連鎖の頂点に位置します。
