Crocodiles and caimans have spine-like protrusions along the top of their bodies. So it helps to study all trees of Mesoamerica which have conical spines or other rough surfaces on their trunks. It took several years to find the elusive Hura polyandra trees and very quickly we noticed that the polyandra species had only very few spines; it was mainly Hura crepitans which had the frankly amazing conical spines everywhere on its trunk. But Hura crepitans is not known for Guatemala; it is further south.

Donations can be sent via wire transfer or through our American Express or Visa accounts. These pods explode with a loud noise and throw their seeds many meters. No one believes that any seed pod can explode with this violence, so we have begun to experiment. Our goal is to study the internal structure of the pod and hope that a student will do a thesis on the internal structure and how the pod explodes in milli-seconds.

We are experimenting with various manners to record this. Clearly our video equipment is rudimentary. Hopefully donations to our institute, FLAAR, will allow us to buy video equipment with stop-motion capability.

Here are first experimental videos. We hope you enjoy learning about the wonders of nature. First set of Videos.

But we quickly learned that there are many more trees with conical spines, most obviously other relatives of the Ceiba pentandrasuch as Ceiba aesculifolia.
