Question

Cryptozoology is the study of and search for animals that science has yet to acknowledge
exist and animals thought to be extinct. The word cryptozoology literally means "the study of
hidden animals." Bernard Heuvelmans (1916–2001) is considered the father of
cryptozoology and often credited with creating the words to describe his own research in the
1950s. While most people associate cryptozoologists with those who hunt for Bigfoot, the
Chupacabra, and the Loch Ness Monster, there are respected scientists who search for new
species of insects, reptiles, birds, and mammals in the little explored region of the tropics.
These scientists, however, are not likely to call themselves cryptozoologists because most
consider the field a pseudoscience. Colleges do not offer degrees in cryptozoology and rarely
offer elective courses on the topic.

But even though the International Society of
Cryptozoology ceased its operations in 1998, avid cryptozoologists continue their searches
and consider their studies and methods as valid as those of recognized scientists
