Marcelle Hutchins produced and edited this interview for broadcast with Tinku Ray. “And they complete whatever process they complete and they create new frogs.” “Once a student is finished with the frog, we gather them up and we send them back to the company,” she says. Plus, schools switching to synthetic frogs is good news for the vulnerable animals: A deadly fungus has pushed hundreds of amphibian species toward extinction over the past 50 years. When the abdominal cavity of the frog is opened, many organs of the digestive and urogenital systems can be observed. Along with toads, they make up the largest group of Amphibians. Frogs have similar body systems (like the digestive and circulatory systems) to other vertebrates like humans, making them a nice specimen for comparative anatomy. SynFrogs cost $150 each, but unlike real frogs, the company recycles the used specimens. Frogs are vertebrates in a class called Amphibians. Schultz and her colleagues later helped Danielson’s company, Tampa-based SynDaver, design a synthetic frog that meets Florida’s standards. David Danielson, he told Schultz about how his daughter didn’t want to dissect a frog in biology class. The synthetic frogs have anatomically-correct, removable organs. “When you cut it open, you have to cut the breastbone of the synthetic frog just as hard and put as much pressure as you would on a regular frog,” she says. Using a synthetic frog prevents this extra step, she says. Now, she says the first-of-its-kind synthetic SynFrogs give her students a “superior” anatomy lesson.įor example, when students cut open a real female frog, the egg sac can break and leave debris to clean up. Principal Jessica Schultz says her school used to buy between 200 to 300 frogs per year from a scientific supply company. “So I think that reduces some of the barriers for some of the other students in the classroom.” “When you bring these synthetic frogs into the actual classroom, nobody is going to be off-put by the fact that it was alive because it's synthetic, of course,” Koney says.

The frogs’ skin and removable organs are realistic in size and color. SynFrogs attempt to mimic the anatomy of a real frog with skin that looks and feels like live tissue. Mitchell High School in New Port Richey, Florida, is taking a new approach to this rite-of-passage educational experience: an anatomically-correct synthetic frog that teaches students about organ systems without harming living animals or using hazardous chemicals like formaldehyde. Principal Jessica Schultz says SynFrogs give her students a “superior” anatomy lesson. That wasn’t a problem when the now senior dissected a synthetic frog, but he says the “wet and slimy” creature felt like a real amphibian.

When Nabil Koney dissected a pig during his freshman year of high school, he says the most memorable part of the experience was the smell.
(Allison Hagan/Here & Now) This article is more than 3 years old. An unopened specimen is guaranteed for up to one year.A synthetic frog. Once opened, the specimen will last for a couple of weeks, do not use specimen if the specimen dries out or begins to grow mold.
If the specimen remains unopened in the vacuum-pack or pail-pack the specimen should last indefinitely.
PLEASE NOTE: Specimens should be stored at room temperature and out of direct sunlight. SHIPPING NOTICE: This item may have a lead time of 4 - 6 weeks before your item is ready to ship, please send us a message via Live Chat or give us a call, 80 for more information. This guide contains 18 pages with 14 detailed illustrations. Each guide covers the relationships between the phyla. Our invertebrate guides have been designed to cover a more comparative view of invertebrate dissection. Geared for the high school student, these guides are also used by grade schools and colleges because they cover the basics, the “take-home message”, for anatomy and comparative anatomy. Each guide is fully illustrated and conveys the complete dissection. Anatomy Lab proudly offers these very popular student guides at prices much lower than other guides.
