==外形特征==
婆罗洲象是亚洲象四个亚种中体型最小的,成年雄性身高也不超过2.5米。它们的面孔象其他象种的婴儿,耳朵很大,尾巴很长,几乎垂到地面。体型更小、更丰满,且性情比其他亚洲象更加温和,婆罗洲的大象种群看上去与其它亚洲象有很大差异,拥有较小的头盖骨和牙齿的变形等。<ref>[http://www.iltaw.com/animal/1186 婆罗洲象Borneo elephant] </ref>
==生态习性==
过去40年来,由于砍伐、改建种植园以及人类居住等原因,位于婆罗洲东北部的马来西亚沙巴州40%的森林消失了,而这里是大多数野生侏儒象生存的栖息地。 调查表明,象群活动显然受到人类活动和森林破坏的影响。收集到的数据显示,生活在沙巴州的侏儒象很可能不到1000头,这比之前估计的1600头要少许多。低京那巴当岸野生动物保护区作为重要的象群栖息地,可能由于面积较小且栖息地破碎,而无法长期满足大量象群的生活需要。
 
==婆罗洲象的英文介绍==
The Borneo elephant, also called the Borneo pygmy elephant, inhabits northeastern Borneo. Its origin remains the subject of debate. A definitive subspecific classification as Elephas maximus borneensis awaits a detailed range-wide morphometric and genetic study. Since 1986, Elephas maximus has been listed as endangered by IUCN as the population has declined by at least 50% over the last three generations, estimated to be 60–75 years. The species is pre-eminently threatened by habitat loss, degradation and fragmentation.
