Invertebrates include crayfish, grasshoppers, earthworms, clams, sea stars, squid, sea urchins, and cockroaches. Most animal species used in dissection are predominantly taken from the wild. These include frogs, spiny dogfish sharks , mudpuppies and other salamanders, birds, snakes, turtles, fish, and most invertebrates. Other animals used in dissection, like fetal pigs and mink, are acquired from slaughterhouses and fur farms. Cats used for dissection are purchased from 'Class B' dealers who obtain cats from a variety of legal and illegal sources, such as animal shelters, 'free to good home' ads, and pet theft.
Seeing and cutting into dead animals, who may once have been someone's companion, can be very traumatic or otherwise difficult for students. Use of animals from slaughterhouses, fur farms, or shelters and pounds neglect the greater problems of animal cruelty, why these animal lives have been wasted, and the animal overpopulation crisis. It instills a utilitarian view of animals, disregarding the study of life, and it promotes desensitization towards animal suffering.
The purchase of cadavers for dissection creates another demand for these cruel industries. Many educators are now questioning the value of the use of animals in education. Dissection specimens for sale includes fish heads, lamb and pig organs, specifically; brain, heart, lungs, eyes, kidney, testicle, tongue, liver and pig trotters as well as whole pluck, lites and tops.
We aim to provide you with all of the necessary dissection samples that you will need whether you are a school, college, university or laboratory. We provide dissection supplies, supplying frozen animal organ samples throughout the UK with next day delivery. If you are already dissecting in lessons, we hope to make your life a lot easier by providing a quick, reliable and easy to use service when sourcing your specimens. All of our specimens are vacuum packed and frozen rather than preserved; making for a safer, odourless and more natural specimen.
Hello Cameron, Thank you very much. It used to be such a trial trying to source decent plucks, eyes etc. Many thanks Lisa. Thank you very much for our delivery. I was very pleased with the ordering process, the delivery and the package and last not least with the quality of the material!
We will definitely order again with you! German School Association ltd. Hi Cameron and colleagues, I have just received the recent order of hearts and fish heads etc. Please may I compliment you on the care of packaging and quality of the items. As students activate many of their senses while dissecting an animal, their memory or recall increases, which helps boost their overall academic performance.
Students who pursue careers in biology including researchers, medical doctors, and teachers will benefit from remembering dissection details. Incorporating activities into your lesson plans is an important thing to do as an educator. Doing an activity, like an animal dissection, brings some FUN into the home or classroom , encourages student participation , and teaches important life concepts.
While it may seem complex, intimidating, or difficult to do, incorporating dissections into your lesson plans is actually pretty easy to do! They fit well into content units, grade and age curriculum, or individual lab projects. With the proper tools and guidance, dissecting an animal is a surprisingly doable and eye-opening learning experience. Use our step-by-step, photographic dissection guides to help you every step of the way! If you'd like to receive a dissection specimen, a dissection guide, and the essential dissection tools all in one, browse our selection of dissection kits and find the perfect one s for you.
Finally, and perhaps most importantly, animal dissections can help students develop a deeper respect for the complexities of life and the natural world.
Remember that icky, overpowering smell from your middle school, high-school, or college life science dissection? It's wasn't the specimens that smelled bad; that foul smell actually came from a chemical preservative called formaldehyde. The smell of formaldehyde in classroom dissections probably turned more than a few students away from studying biology further! Fortunately, most of our animal suppliers use formalin to embalm their dissection specimens.
Formalin is a colorless and mostly odorless solution of formaldehyde in water. We understand that humane practices are a concern for many when it comes to dissection.
It is important for us to communicate that source most of our dissection specimens from companies in the United States. Because of this, most of our suppliers are subject to inspections and compliance orders from the US Department of Agriculture, under the Animal Welfare Act. In addition, many of the animals used for educational dissections are often the byproducts of other industries. For example, fetal pigs come from pork manufacturers and skinned minks come from fur ranches.
Rather than sending the bodies of these animals to the landfill, suppliers use them for educational purposes. Ordering small animal specimens for your dissections is an affordable choice. These specimens save you money, arrive at your door quickly, take up less room in storage, and require less working space in the lab!
Because small animals have shorter life cycles and reproduce more quickly than large animals, their anatomies are more simple and less "human-like. Small specimens are perfect for first-time dissections!
Some excellent smaller specimens include earthworms , crayfish , starfish , clams , grasshoppers , and frogs! For the slightly more experienced dissection explorers, larger animals are a great way to go. These animals have more complex organs and internal anatomies, making them perfect for more advanced biological studies. Plus, some of their organs i. Finding anatomical similarities helps enhance a student's comprehension and tangible application. Another benefit of dissecting a larger animal is greater visibility!
