Bregmaceros mcclellandi species, abundant along the north-west coast of India, are economically valuable and ecologically vital marine resources. A comparative analysis of an malpigmentation specimen and a normal specimen indicated no differences in the morphometric and meristic characteristics. The specimen recorded in the present study was a mature female with a total length of 101 mm and a total weight of 4.6 g. The hyperpigmentation was recorded around the pectoral region, covering approximately 6% of the total body surface of the anomalous specimen. The present observation of hyperpigmentation in B. mcclellandi is the first recorded instance of hyperpigmentation in the family Bregmacerotidae, and the finding is novel due to the rarity of such a phenomenon in the wild population.

Bregmaceros mcclellandi种，沿印度西北海岸丰富，是经济价值和生态重要海洋资源。对色素沉着标本和正常标本的比较分析表明形态测量和分生特征没有差异。本研究中记录的标本是一只成年雌性，总长度为 101 毫米，总重量为 4.6 克。胸廓周围记录了色素沉着过度，覆盖了异常样本全身表面的约6%。B. mcclellandi色素沉着过度的现状观察 这是 Bregmacerotidae 家族中第一个记录到的色素沉着过度实例，由于这种现象在野生种群中很少见，这一发现是新颖的。
