David M. Schleser was trained as a dentist, a profession which he practiced for 19 years. In 1982 he changed careers to aquatic biology, and later served for over five years as the Curator/Aquatic Biologist for the Dallas Aquarium, Dallas, Texas. He recently resigned this position to work full time for Nature's Images, Inc., a natural history photography and writing company which he helped establish. Since 1988, he has traveled regularly to the rain forests of Costa Rica, and the Amazon regions of Peru and Brazil, for purposes of research and photography. He frequently serves as the tour leader for Amazon River ecological and tropical study expeditions. David Schleser photographs and writings have appeared in many scientific and popular publications. He is also a Tetra speaker and presents many lectures on aquatic subjects to aquarium societies throughout the United States and Canada. His major ichthyologic interests are South American characins, the Centrachids of North America and desert fishes.

It is my personal opinion that Piranhas, A Complete Pet Owner's Manual is the best amateur piranha book published in the last 40 years. I highly endorse it to anyone interested in learning about piranhas as home pets.

This caught specimen is a bit controversial. It is not found in the river locale that Schleser said he found the fish in. Slide has this remark: P. striolatus Rio Nanay (October 1988).

This caught specimen is a bit controversial. This fish was captured in an area where it is not found at all. Schleser wrote this on the back of the slide, "P. striolatus, Rio Nanay, (October 1988)."
