"Each paragraph of the text of Aristotle is printed in a new and an old translation, and is followed by the commentary of Averroes on the latter (BMC)" (ISTC No. IDia00969000).

Because of the supreme position of Aristotle in the medieval scientific and philosophical curriculum certain Aristotelian texts were among the first scientific texts to be published in print.

Includes Aristotle's De historia animalium, De partibus animalium, and De generatione animalium. Aristotle was the first scientist to gather empirical evidence about the biological world through observation. By his careful observations and excellent accounts of the natural history of those living creatures which he was able to investigate in De historia animalium Aristotle may be considered the first scientific naturalist. English translation in his Works...edited by J. A. Smith and W. D. Ross, Oxford, 1910, vol. 4.

Aristotle's De partibus animalium is the first animal physiology. English translation in his Works edited by Smith and Ross, vol. 5. That edition excluded annotations by the translator,  William Ogle, that were published in the edition of London, 1882.

Aristotle's De generatione animalium is the first textbook on embryology. "The depth of Aristotle's insight into the generation of animals has not been surpassed" (Needham). English translation in his Works, edited Smith & Ross, vol. 5. Later translations are also available.

Aristotle, at one time tutor to Alexander the Great, was, among other things, the first observational biologist, and the founder of comparative anatomy. His views had a profound influence in determining the direction of biological thought, as well as scientific thought in general. The Augsburg 1479 edition is the first of ten printed editions of Aristotle's works in Latin issued in the 15th century, and like all of them, it represents selections rather than his complete works. The 1479 edition is ISTC No. ia00960000. Digital facsimile from the Bayerische Staatsbibliothek at this link. 

First edition of the collected works of Aristotle with the commentaries of Averroes, by which Aristotle was mainly studied during the Middle Ages. The purpose of Vernia's edition was to provide an accurate edition of Averroes's commentaries. These were first printed in Padua, 1472-1473. As usual, various different translators were involved in this collected edition, and a few texts by authors other than Aristotle were added. The 8 parts of the set were:

Between November 1495 and June 1498 scholar printer Aldus Manutius (Teobaldo Mannucci) of Venice issued the first edition in the original Greek of Aristotle's Opera omnia. The set appeared in five thick quarto or small folio volumes, often bound in six. Assembling all of the texts was a major challenge for Aldus and his associates, requiring the help of scholars in different countries, and yet during the publication process Greek texts of both the Poetics and On Rhetoric, remained elusive, so they were excluded from the set. The editio princeps of Aristotle appeared at the close of a century that had witnessed a strong revival in Greek and humanistic studies; it was the first major Greek prose text, or collection of texts, to be reintroduced to the Western world in its original language by means of the printing press, and its success launched Aldus's efforts to produce further editiones principes of other Greek authors. In addition to the Aristotelian works, the five volumes contained works by Aristotle's successor, the botanist Theophrastus, the commentator on Aristotle, Alexander of Aphrodisias, the neo-Platonic philosopher Porphyrius, and Philo of Alexandria (Philo Judaeus) along with the spurious De historia philosophia attributed to Galen.

Michael of Ephesus, who completed his commentaries in or after 1138, was one of the principal Aristotelian scholars in a group organized in Constantinople by the Empress Anna Komnena. His commentary was translated into Latin by Domenico Montesauro, a physician of Verona. In the present edition Michael's work is followed (pp. 201-325) by a version in Latin of book I of the original Aristotle, with facing commentary, by the Padua philosophy professor Niccolo Leonico Tomeo (1456-1531).

Loeb Classic Library. 

The Commentaria in de motu et de incessu animalium by the Byzantine writer Michael of Ephesus are the only surviving commentaries in Greek on Aristotle's De motu animalium and De incessu animalium.

Reprinted with corrections, 1995. "The Oxford Translation of Aristotle was originally published in 12 volumes between 1912 and 1954. It is universally recognized as the standard English version of Aristotle. This revised edition contains the substance of the original Translation, slightly emended in light of recent scholarship; three of the original versions have been replaced by new translations; and a new and enlarged selection of Fragments has been added. The aim of the translation remains the same: to make the surviving works of Aristotle readily accessible to English speaking readers" (Publisher).

Critical edition based on a collation of the 26 known extant manuscripts and a study of the early Latin translations.

Volume I of the edition contains the complete text of the Historia Animalium, the critical apparatus, and Balme's introduction to the manuscripts, expanded and updated with the assistance of Friederike Berger, and in consultation with the editors of forthcoming editions of the extant medieval translations.
