花斑拟鳞鲀(学名:Balistoides conspicillum):俗名小丑炮弹,栖息于珊瑚丛生之珊瑚礁区,日间活动,以小型甲壳类及软体动物为食。幼鱼全身满布斑点,成鱼后,胸鳍以上的斑点便会逐渐消失,眼睛藏在深色的头部之中。于眼睛下方有一浅色色带,有欺敌的作用,能使敌人误以为是眼睛部位,避免眼部受到直接攻击。受到惊吓与睡觉时会用背鳍及腹鳍腰带撑直卡紧珊瑚礁洞穴,增加敌人掠食的困难。在野外,主要生活在珊瑚礁地区,寻找贝类及无脊椎动物取食。肉有毒,非食用鱼。由于色彩鲜艳,为具高价值的观赏鱼。分布于印度洋至太平洋区。
Balistoides sympicillum (scientific name): commonly known as clown shell, it inhabits the coral reef area with corals. It is active during the day and feeds on small crustaceans and molluscs. The young fish are covered with spots. After the adult fish, the spots above the pectoral fin will gradually disappear, and the eyes are hidden in the dark head. There is a light color band under the eyes, which can deceive the enemy, make the enemy mistakenly think it is the eye part, and avoid direct attack on the eyes. When frightened and sleeping, they will use their dorsal fin and abdominal fin belts to straighten and clamp the coral reef caves, making it more difficult for the enemy to prey. In the wild, it mainly lives in the coral reef area, looking for shellfish and invertebrates for food. The meat is poisonous, not edible fish. Because of its bright colors, it is a high-value ornamental fish. It is distributed from Indian Ocean to Pacific Ocean.
