Longear sunfish are deep, slab-sided fish with a small mouth. They get their name from their long ear flap, or opercle. There are two subspecies found in Ohio, the northern longear sunfish (Lepomis megalotis peltastes) and the central longear sunfish (Lepomis megalotis megalotis). The opercle is nearly all black with a white margin. The opercle of the central longear usually runs parallel to the fishes' body and may have several small red spots in the white margin. The opercle of the northern longear is smaller and often points backward at an upward angle rather than being parallel. Northern longears also have a large red spot at the back edge of the opercle. Longear sunfish have emerald blue wavy lines running from the mouth to the rear edge of the gill cover. The back is olive-green with blue-green specks on the side, and the belly is orange, red or yellow. Breeding males are brilliantly colored with the red and blue coloration on their face and body becoming more intense during this period. Females are less intensely colored and do not have as long of an opercle as males. Members of the Centrachidae (sunfish) family. The central longear is typically 4-7 inches, but can reach 9 inches, and the northern longear is typically 2.5-4.5 inches, but can reach 5.5 inches.

长耳太阳鱼最最大长度可以达到24厘米,最重的记录是790克,寿命一般在六年以内。最大的特点便是鳃盖皮瓣延长,神似长长的耳朵,因此被称为长耳太阳鱼。英文名 longear 也是长耳的意思,国内水族商品名谐音叫嫦娥。长耳太阳鱼喜欢水草丰富的湖泊、池塘以及溪里缓流浅水区,食物包括昆虫、水生无脊椎动物以及小鱼,不过长耳太阳鱼更善在流水觅食,所以资料上讲此鱼在溪流里比湖泊更常见,我个人的经验也证明了这个说法,从小型到中型溪流,都很常见。作为太阳鱼属的成员,在繁殖期,雄鱼会筑巢、并且有护巢行为. 成年人可以长到9.5英寸的最大长度和约1.5磅的重量。
