Species that are absent include all of the numerous varieties of snails in Taiwan, the various kinds of edible animal species that are being endangered by over-fishing and over-culling along the coasts, and even Taiwan's endemic ruanchih moth (Neopseustis meyricki), which has a history of more than 100 million years.
至於台灣特別豐富的特有種陸貝，與沿海許多遭竭澤而漁的生物，甚至有上千萬年生存歷史、仍保持遠古蛾類型態的台灣特有卵翅蛾，完全缺席。
