Zeeshan Ayaz Mirza (born March 1988) is an Indian herpetologist and arachnologist, who is a doctoral candidate at the Max Planck Institute for Biology in Tübingen, Germany. Specializing in systematics, molecular phylogenetics, and taxonomy, Mirza is recognized for having described more than 60 new species of reptiles and arachnids, including snakes, tarantulas, geckos, and scorpions. His discoveries include species of significant media interest, such as the snake Trimeresurus salazar, named after the Harry Potter character Salazar Slytherin, and Anguiculus dicaprioi, named in reference to actor Leonardo DiCaprio. Mirza also described the tarantula genus Cilantica in 2024, endemic to the Western Ghats of India. His research focuses primarily on the biodiversity of the Western Ghats and the Himalayas, two of India's most important biogeographic regions.
Early life and education Zeeshan Ayaz Mirza was born in Mumbai in March 1988 and grew up near Aarey Milk Colony, an urban green area located in the city's suburbs. His interest in nature developed from childhood, when he explored local biodiversity and conducted snake rescues in the Mumbai metropolitan area. By age 22, Mirza had accumulated field experience equivalent to that of researchers twice his age and had published more than 20 scientific papers. Mirza graduated with a Bachelor of Science in zoology from Bhavan's College, affiliated with the University of Mumbai, and subsequently completed a master's degree in life sciences. His academic journey was marked by an unconventional path, with strong emphasis on field work and independent research from his undergraduate years. During this period, he initiated collaborations with Indian and international research institutions, establishing the foundations for his prolific scientific career. Currently, Mirza is a doctoral candidate at the Max Planck Institute for Biology in Tübingen, Germany, where his research has shifted focus to developmental biology, studying developmental plasticity in nematodes of the genus Pristionchus. Despite this shift in research area, he maintains active collaborations in herpetology and arachnology, continuing to describe new species and revise complex taxonomic groups.
Career and research Mirza's scientific career began in earnest during his undergraduate studies, when he started documenting the reptile and arachnid fauna near Mumbai. His first taxonomic paper on snakes not only described a new species but also established a new genus, marking the beginning of a series of significant contributions to Asian vertebrate and invertebrate systematics. Before joining the Max Planck Institute, Mirza was a research associate at the National Centre for Biological Sciences (NCBS), affiliated with the Tata Institute of Fundamental Research in Bangalore. At this institution, he developed much of his research in reptile and arachnid systematics, with emphasis on integrative approaches combining morphology, molecular phylogenetics, and biogeographic analysis. His field research spans various regions of India, with special focus on the Western Ghats and the Himalayas. Between 2014 and 2024, Mirza conducted extensive expeditions through states including Arunachal Pradesh, Mizoram, Himachal Pradesh, Kerala, Tamil Nadu, and Karnataka. A single month-and-a-half expedition to Arunachal Pradesh in 2019, for example, resulted in the discovery of three new snake species, two new bent-toed gecko species, and an entirely new genus of lizards. Mirza works regularly in collaboration with other researchers, with Rajesh Sanap being one of his main collaborators in arachnid studies. His methodologies include detailed morphological analyses, DNA sequencing, phylogenetic studies, and comprehensive taxonomic revisions. Notably, Mirza has also incorporated unconventional tools into his research, such as using social media for species identification. In 2020, during the COVID-19 pandemic, a photograph of a snake posted on Instagram by Virender Bhardwaj led Mirza to identify a new species, Oligodon churahensis, from Churah Valley in Himachal Pradesh. His areas of expertise include the snake genera Trimeresurus, Oligodon, Liopeltis, and Gongylosoma, as well as various groups of arachnids, including tarantulas from the subfamilies Thrigmopoeinae and Eumenophorinae, and geckos from the genera Cnemaspis, Gekko, and Hemidactylus. With over 70 published scientific papers and 857 citations on Google Scholar, Mirza has established himself as one of the leading authorities on Indian subcontinent biodiversity.
Notable discoveries
Snakes One of Mirza's most widely publicized discoveries was Trimeresurus salazar, a green pit viper found in Arunachal Pradesh in 2020 and named after Salazar Slytherin, a character from J.K. Rowling's Harry Potter series. The species was discovered near Pakke Tiger Reserve and is characterized by a unique orange-red stripe along the head and body of males. The name choice was motivated by Slytherin being a wizard capable of speaking to snakes (Parselmouth) and founder of Slytherin House, whose symbol is a serpent. In 2024, Mirza described Anguiculus dicaprioi, a Himalayan snake named in honor of actor Leonardo DiCaprio for his environmental activism. The discovery was initiated when a photograph of the snake was posted on Instagram by Virender Bhardwaj in June 2020, during the COVID-19 pandemic. Mirza, upon viewing the image in his timeline, recognized it as a potentially new species, leading to three years of detailed investigations that confirmed not only a new species but an entirely new genus, Anguiculus. Another notable case involving social media was the discovery of Oligodon churahensis, from Churah Valley in Himachal Pradesh, also resulting from a photograph shared on Instagram. In 2016, Mirza described the genus Wallaceophis, named in honor of Alfred Russel Wallace, the British naturalist who formulated the theory of natural selection independently of Charles Darwin. The species Wallaceophis gujaratensis was discovered in Gujarat, a region considered less biodiverse in India, highlighting the need for scientific exploration in neglected areas. Mirza is a great admirer of Wallace, stating that "everybody knows Darwin, but nobody knows his contemporary genius, Wallace".
