[2][3][4] In a 2012 interview, Shuker stated that three of the most important zoological discoveries of the twentieth century were the okapi, the coelacanth and the saola (or Vu Quang ox).

"[6] Shuker engages in what he describes as the scientific investigation of "animals still awaiting formal zoological detection and description in the 21st century.

Having investigated the mystery of the chupacabra, Shuker noted in an interview with Benjamin Radford that the inconsistencies surrounding descriptions and accounts of the creature made it difficult to separate actual reports from folklore.

"[11] In June 1997 Shuker criticized Fortean Times publisher Mike Dash, who has described most reports of strange phenomena to be products of the imagination, to which Shuker stated, "there are some intriguing pieces of evidence for the existence of a large underwater mammal in Loch Ness, not least the sonar soundings of 1972 which showed the presence of a 6-ft flipper.

"[13] Reviewing Shuker's 2003 book The Beasts that Hide from Man, Mark Bayless described the work as "thought provoking and well researched," contrasting Shuker's work favorably against other cryptozoology texts as providing a "scholarly, reader-friendly format," and addressing a wider range of cryptids that are not covered in comparable sources.
