Comparison of Limbs in Vertebrates
Product Code : SCL-BLE-11716
Comparison of Limbs in Vertebrates (SKU SCL-BLE-11716) is an enlarged three-dimensional model that sets the limbs of 5 types of vertebrates side by side, so students can compare the bones and see the shared pattern behind very different uses. Moulded in PVC and coloured with non-toxic dyes, it supports evolution and comparative anatomy lessons from Class 12 to B.Sc. zoology. Science Lab Supplies can deliver it from Ambala, India to schools, colleges, contractors and distributors on request.
Specifications
The model's specification is set out in the table that follows. In short, the limbs of 5 vertebrate types are reproduced in enlarged form as one three-dimensional model, moulded in PVC and finished with non-toxic dyes, ready for a teacher-led comparison of their bones.

Applications and Experiments for the Vertebrate Limb Comparison Model
The model is used to show homologous organs: limbs built on the same basic plan of bones that have been adapted for different jobs such as walking, swimming, flying or grasping. Students match corresponding bones across the 5 limbs and discuss how common ancestry explains the similarity.
- NCERT Class 12 Biology, Evolution: anatomical evidence and homologous organs.
- Class 9–11 biology: diversity and classification of vertebrates.
- B.Sc. zoology, comparative anatomy: the pentadactyl limb and its modifications.
- Naming the human arm bones first on the Human Skeleton Model, Life Size PVC, and covering bone structure with the Anatomical Construction of the Bone chart.
Standard Scope of Supply
Supply covers one enlarged PVC model showing the limbs of 5 types of vertebrates, coloured with non-toxic dyes. Skeletons, preserved specimens and evolution charts are separate items; they can join this quotation when a comparative anatomy or evolution corner is being assembled.
Packing, MOQ and Lead Time
One model is enough for a teacher-led demonstration, and several can be quoted for group work or multiple schools. Each quotation from Science Lab Supplies covers packing, delivery time and price for the quantity named, and skeletons or evolution charts can be included on the same quotation.
Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in Zambia, Rwanda, South Africa, Qatar, Sri Lanka and Vietnam. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Price requests for the limb model are welcome on the contact page or through the enquiry cart, while the lab tender page sets out how bids are handled.
Frequently Asked Questions
What does the model teach?
It teaches homology. By comparing the limbs of 5 vertebrate types, students see that the same set of bones has been adapted for different functions, which is a classic piece of anatomical evidence for evolution.
Is the model life size?
No. The limbs are reproduced in enlarged form so the individual bones are easier to point out and compare across all 5 vertebrate types. The model is moulded in PVC and coloured with non-toxic dyes.
Who supplies the Comparison of Limbs in Vertebrates model?
Biology buyers obtain this model from Science Lab Supplies, operating from Ambala, India, which prices it, packs it and dispatches it alongside skeletons, specimens and charts ordered for the same laboratory.
Can it be quoted with preserved specimens?
Yes. The frog, lizard and chicken dissections in this range let students compare whole vertebrate bodies, and they can be priced together with the limb model on a single quotation.
Related Comparative Anatomy and Evolution Aids
Skeletons, evolution charts and preserved vertebrates extend the limb comparison into full lessons on anatomy and evolution. Each item below can be added to the same quotation as the limb model, so a biology department can equip a comparative anatomy display from one supplier and one document.
