🐍Eastern green mamba
ヒガシグリーンマンバ（学名：Dendroaspis angusticeps）は、コブラ科に分類されるヘビ。別名はトウブグリーンマンバ。強力な毒蛇であり、東アフリカ南部の海沿いに分布する。体は細長く、背側は黄緑色、腹側は黄色である。雌の方が大型であり、全長2mに達する。 攻撃的で素早く、人を追いかけると言われることもあるが、実際には性質は大人しく、木に隠れているため見つけるのも難しい。緑色の体色は、生息地である木の中で擬態の役割を果たす。強い毒を持つものの、猛禽類や他のコブラといった天敵が存在する。積極的に狩りを行う他のコブラ科のヘビとは対照的に、クサリヘビ科のような待ち伏せ型捕食者である。鳥類とその卵、コウモリ、ネズミなどを捕食する。 毒は神経毒と心臓毒の両方を含む。腫れ、めまい、吐き気、脱水症状、呼吸困難、嚥下障害などの症状を引き起こす。その後は不整脈や痙攣、呼吸不全によって、脳への酸素供給が致命的に不足する可能性もある。重度の場合は素早く治療しなければ死に至る可能性もある。
