Read full description

Designed for institutional use by animal care specialists, ZooMorphTrak allows estimation and comparison functions for the bodyweight of Bottlenose Dolphins (Tursiops truncatus). The inputs to the calculations are the dolphin's sex, age (if known), length, and girth. Weight can be estimated from these measurements using a simple tape measure, and without requiring a scale nor to train the dolphin to cooperate with weight measurement. * The “Approximate” feature allows users to input measurements (sex, age, length and girth) and receive an approximate bodyweight. * The “Management” feature compares the bodyweight of a managed individual to the bodyweights of wild dolphins. The user enters the sex, age, length, and girth, and the measured weight. A comparison is made against reference ranges observed in wild dolphins. The prediction equations in this program were derived from long-term studies of dolphins both in the wild and in professional managed care.

Then print it, share it or save it to Files. • FOUR RELEASE TYPES — adult model, talent / performer (name, likeness, voice and performance), minor model with parent or guardian, and property release. • YOUR DETAILS FILLED IN — photographer or company, subject name and address, plus optional date, location, project name and consideration (for example “$1” or “a copy of the photos”). • CLEAR LAYOUT — a titled document with Parties, Agreement, optional Additional Notes and a Signatures section with signature, printed name and date lines for each party, plus an optional witness line. • PRINT, SHARE OR SAVE — print with AirPrint, share the PDF, or save it to Files. • NO BLANK GAPS — anything you leave out is simply omitted from the wording, and if no consideration is entered the standard “good and valuable consideration” phrase is used.
