在东方鲀属的几种河豚鱼的皮肤中发现了独特的外分泌腺或腺样结构。T. pardalis和T.虫体由分泌细胞和大液泡组成。这些细胞完全封闭的上皮细胞与发达的微丝，除了在其开口的管腔。当刺激河豚鱼时，其特有的分泌细胞中的大空泡中的内容物被挤出。在皮肤中还发现有外分泌腺或腺样结构，并有特殊的分泌细胞。poecilonotus、T. niphobles和T.辐射虫直接从活的T. pardalis。因此，我们得出结论，这些腺体是TTX分泌腺。
Unique exocrine glands or gland-like structures were found in the skin of several species of puffer fishes of the genus Takifugu. The glands of T. pardalis and T. vermiculare porphyreum consisted only of secretory cells with a large vacuole. These cells were completely enclosed by epithelial cells with developed microfilaments, except at their opening to the lumen. The contents of the large vacuole in the peculiar secretory cell were forced out when the puffer was stimulated. Exocrine glands or gland-like structures with peculiar secretory cells were also found in the skin of T. poecilonotus, T. niphobles and T. vermiculare radiatum. A high concentration of TTX was detected in the gland contents collected directly from live specimens of T. pardalis. We therefore conclude that these glands are TTX secreting glands.
