Nectar Drops from Srila Prabhupada
"Out of 8,400,000 different forms of life, we civilized human beings are very few. But others, their number is very great. Just like in the water: jalajā nava-lakṣāṇi (Padma Purāṇa). There are 900,000 species of life within the water. Sthāvarā lakṣa-viṁśati: and 2,000,000 different forms of life in the vegetable kingdom, plants and trees. Jalajā nava-lakṣāṇi sthāvarā lakṣa-viṁśati, kṛmayo rudra-saṅkhyayaḥ: and the insects, they are 1,100,000's different species of form. Kṛmayo rudra-saṅkhyayaḥ pakṣīṇāṁ daśa-lakṣaṇam: and birds, they are 1,000,000 species of forms. Then beasts, paśavas triṁśa-lakṣāṇi, 3,000,000 types of animals, four-legged. And catur-lakṣāṇi mānuṣaḥ, and the human being, the forms are 400,000."
