The Asian giant softshell turtle, Pelochelys cantorii (Trionychidae), is endangered and was designated as a First Grade Protected Animal in China in 1989 and listed as Endangered on the International Union for Conservation of Nature Red List in 2000; the species has suffered a gradual reduction in its range, its total population has decreased, and the need to protect this species has been ignored. We investigated 13 nature reserves with P. cantorii as the main object of protection and 5 captive-breeding centers; we also present the results from a questionnaire sent to one nature reserve. We summarize the distribution and habitat characteristics, evaluate the species' conservation status in each nature reserve, analyze the causes of extinction, and put forward our proposal for the protection of P. cantorii.

The understanding of developmental and reproductive migrations of sea turtles is essential for effective protection and conservation efforts. Flipper tags remain a valuable method for detecting movements and migrations because they are cost-effective and conspicuous, allowing the detection of a tagged animal by any person worldwide. Here we report 13 flipper-tag recoveries for Brazilian hawksbill (Eretmochelys imbricata) turtles that augment the body ofinformation on the migratory nature of this species and provide new growth-rate data.

Swimming behavior and speed of green turtle (Chelonia mydas) and hawksbill turtle (Eretmochelys imbricata) hatchlings swimming offshore were compared between individuals that were free swimming and the same individuals towing a float. Towing a float did not influence swimming behavior in either species, but decreased swimming speed by 20% in green turtles and 50% in hawksbill turtles.
