וַיַּ֣עַשׂ אֱלֹהִים֩ אֶת־חַיַּ֨ת הָאָ֜רֶץ לְמִינָ֗הּ וְאֶת־הַבְּהֵמָה֙ לְמִינָ֔הּ וְאֵ֛ת כָּל־רֶ֥מֶשׂ הָֽאֲדָמָ֖ה לְמִינֵ֑הוּ וַיַּ֥רְא אֱלֹהִ֖ים כִּי־טֽוֹב׃
上帝造了地上的野獸，各從其類；造了牲畜，各從其類；又造了地上一切爬行的動物，各從其類。上帝看這是好的。
Rashi
ויעש AND HE MADE — He formed them with their full volition and in their full stature (Chullin 60a).
Radak
ויעש אלוקים, the reason why the Torah reports G’d as ויעש, completing something after having already written ויהי כן signaling that G’d’s directives had been carried out, is that G’d’s directive consisted of 3 parts in addition to the directive to create man, i.e. domestic mammals, free-roaming mammals and creeping creatures. G’d constructed each category in such a way that they would make their habitat on different parts of the earth. This has been emphasised by the words למינה, למחנה, למינהו, being inserted between the names of each category of creatures.
G’d did all this in order that one category of creature should not inflict harm, damage on its counterpart by interfering with the other’s lifestyle in its respective domain. This is also the reason why He did not bless them. How could G’d have blessed them with the formula: “be fruitful and multiply and fill the earth,” seeing that He did not want that the harmful creatures amongst them would multiply in such a fashion? Some of these animals’ very grazing on the earth would be a form of causing irreparable harm on the surface of the earth. Our sages (Rashi on verse 22) claim that the reason G’d did not extend His blessing to these beasts was on account of the serpent which became a destructive force.

“And G-d made the beasts of the earth according to their kind” – He gave to each species senses and capacities in accordance with what was necessary for that species.
