Please leave the area cleaner than you found it. If surveying more than one site, wash your net and sampling bucket between sites. A distinction is now generally drawn between malformations those distorted features arising from developmental errors, and deformities the distortions resulting from trauma, such as a limb which has been bitten off. Trauma related deformities are less frequently found, and may difficult to distinguish. As you begin to see more and more frogs, malformations will be easier to spot.
Some malformations are quite subtle.
A good example is a missing digit. You need to count the digits on each foot to spot this one. Abnormal skin color has also been recorded. If you find malformations not listed on page two of the survey, please note them in the section reserved for comments. Because of the possibility of broken bottles in the water, footwear is recommended.
