Sharaf al-Zamān Ṭāhir al-Marwazī, known as Marwazī, was an 11th–12th century physician and writer (fl. 1056/57–1124/25 CE). He came from Merv in the Khorasan region (today part of Turkmenistan). He wrote Kitāb Ṭabāʾiʿ al-Ḥayawān al-Baḥrī wa-al-Barrī, commonly called Nature of Animals, a five-part book about animals of land and sea. He based his work on earlier scholars such as Aristotle, Dioscorides, Galen, Oribasius, Timotheos of Gaza, Paul of Aegina, and Al-Jahiz. Al-Marwazī served as a physician at the courts of the Seljuk sultans, including Malik-Shah I, and he recorded observations of parasitic worms.
