embryo hatches, experiments suggest that the embryo influences other eggs to somehow also hatch. Research limitations One study focused on best practices for tracking the frogs for field research and found that neither bobbins or radio tags were perfectly suited for the frog. Initial attempts of using fluorescent dye proved ineffective as the dye had a deleterious impact on the frog. Bobbins and radio tags had no significant effect on the distance the frog traveled, even though the tracking devices were typically 15 to 20% of the frog's weight. However, frogs became lethargic and less mobile by the third day of the trial. The radio tag failed to locate the frogs in areas of high altitude or vegetation as the signal became less clear. On the other hand, placing bobbins on the frogs often led to physical harm like bruising. References trinitatis Amphibians described in 1926 Taxonomy articles created by Polbot
