There are several species on Celebes and its offshore islands, but most have not yet been described scientifically. No, tarsiers are not dangerous to humans. On average, groups only consist of a single male, known as an alpha male by some. But observations suggest that lorises can take down these animals and eat them fairly quicklyno paralysis needed. This taxonomic discrepancy is strongly supported by data collection of physiological attributes such as coat colors, tail lengths, and size, as well as molecular data (Groves and Shekelle, 2010).
