Morelet's crocodile (Crocodylus moreletii), also known as the Mexican crocodile, is a modest sized crocodilian found only in fresh waters of the Atlantic regions of Mexico, Belize and Guatemala. It usually grows to about 3 metres (9.8 ft) in length. It is an endangered species.

Morelet's crocodile was discovered in Mexico in 1850 and named after the French naturalist who made the discovery, P.M.A. Morelet (1809–1892). It was long confused with the Cuban crocodile and the American crocodile because of similar characteristics. It was not realized that they were a separate species until the 1920s. Present day crocodilians come from an ancient lineage comprising over 125 genera.

Morelet’s crocodile is small in size compared to some other crocodiles. The males can become larger than the females; this is known as sexual dimorphism. The adult crocodile averages around 3 metres (9.8 ft) in length with a maximum reported length of 4.3 metres (14 ft) and is similar to American and Cuban crocodiles in appearance.

Shawn Heflick (born June 17, 1969) is an explorer, adventurer, biologist and current TV host for Python Hunters on National Geographic Wild.

Heflick was born in Akron, Ohio. He grew up on a farm outside of Marion, Ohio living the life most farm boys did, which was running the woods and fields with his dogs. At age 7, he knew he wanted to be a biologist and to work with animals. He attended Pleasant High School, after moving into a more residential farming community. He graduated in 1987. Wanting to go to college to earn his biology degree, but not having the money for it, Heflick joined military service and volunteered to go to Central America. He was not disappointed with what he found and his love for exotic exploration and adventure was born. He enrolled in Wright State University to gain a degree in biology and met his future wife, Jennifer, the first week he was there. During these college years, he worked multiple jobs to make it through. Heflick worked at a vet clinic, a physiology lab and was security at a bar to name a few. He graduated in 1994 and married Jennifer before moving down to Melbourne, Florida to enter graduate school at the Florida Institute of Technology.
