My last visit to Venezuela was in 2005 during which my cousins took me to visit the massive Las Macaguas Dam in Ciudad Guayana. As we walked the site, we eventually entered, in the “innards” of the structure, a small museum dedicated to the creatures encountered during the years of study and construction of Las Macaguas and also the even greater Guri Dam, the second or third largest in the world — sadly saddled with colossal incompetence resulting in far reaching failures for the entire country.

Corporate media reports, including Wikipedia, blame droughts for these life-threatening failures. However, to put it as diplomatically as possible, droughts did not suddenly show up with Chavez and Maduro. For further reading on the deterioration of Venezuelas electrical grid, refer to my posts on the Cuba-Venezuela nexus, such as here.

As we walked the museum we were awed by the variety and gigantic sizes of the insects on display. Childhood memories flooded back as I recalled seeing many of those or similar specimens live-and-in-color as we tramped about El Pao or fished in the Caroní or Orinoco rivers.

A recent email exchange with George and Richard Scheipe, the sons of a gentleman who taught school in El Pao in the 1950s, brought those memories back. George tells of John Tuohy, one of the “older kids” in El Pao, who had come to visit his brother, Ted Heron, Jr., in Pennsylvania, and had brought a dead giant centipede in his suitcase. The mischievous ones hid the critter in aluminum foil in the backyard and “would torment the local kids, including me, with it.” 

These centipedes are the Scolopendra gigantea and are found almost exclusively in South America (but also southern Mexico) with many in Venezuela. They are venomous and their bite can be fatal to small children. In 2014 a 4-year-old in Venezuela died from a bite he incurred when he picked up an empty soda can into which a Scolopendra had hid. In 2015 a 19-year-old man was hospitalized in San Tomé and when he worsened he was taken to a major city for better care. He recovered.

These centipedes can grow as large as 12 inches and are very quick. They are carnivores who feed on any other animal it can overpower and kill, including other arthropods, insects, small birds, lizards, frogs, and snakes. Students have investigated their feeding on bats, something which was not known until relatively recently.

They “climb cave dwellings and hold or manipulate their heavier prey with only a few legs attached to the ceiling.” A study done in southern Mexico discovered that, contrary to earlier belief, bats were killed by these giants pursuant to clever hunting tactics.

It had been believed that the centipedes killed the bats in reaction to being disturbed by the latter when flying in or out of their caves. Careful observation disclosed that the hunters attach themselves to the high walls or ceilings waiting for their prey to fly close, upon which the Scolopendra pounce. “We have observed that, during the trajectory taken by the bats, some perch momentarily. It is during such brief stops that the giant centipede attacks and kills [he who hesitates is lost!].” Also, it is probable that as a bat flies very close to the walls it is also attacked and killed.

I appreciate the recollections of folks who lived in or who have some connection with mid-20th-Century El Pao. Truly we were blessed and had memorable — sometimes frightening — encounters with a unique flora and fauna which so fascinated great explorers such as Alexander Humboldt and others.
