Product Description

Life Cycle of Frog Model on Board – Educational Amphibian Teaching Model

The Life Cycle of Frog Model on Board is an educational zoological relief teaching aid engineered to demonstrate the developmental stages, physiological adaptations, and metamorphic transformation of an amphibian (Hoplobatrachus tigerinus / Rana sp.). Cast in high relief from high-density, unbreakable medical PVC polymer or reinforced fiberglass and mounted securely on a finished display baseboard, this model accurately represents embryonic and larval development from aquatic beginnings to terrestrial maturity. It serves as an essential teaching benchmark across secondary school biology classrooms (SSC/HSC), university zoology departments, teacher training academies, and primary science laboratories throughout Bangladesh.

Understanding amphibian metamorphosis, gill-to-lung respiratory transition, and tail resorption can be difficult for students when relying solely on flat textbook sketches or temporary aquarium observations. This relief board model resolves that learning barrier by providing an open, chronologically organized progression of frog development. The sequence begins with fertilized egg clusters encased in protective gelatinous envelopes (frogspawn), progressing into early cleavage stages, embryo formation, and freshly hatched aquatic larvae clinging to aquatic weeds with adhesive suckers.

The model details subsequent larval adaptations, showcasing external gill formation, functional finned swimming tails, and the transition to internal gills covered by an opercular fold. Further relief figures capture key metamorphic transformations: the eruption of muscular hindlimbs, followed by forelimb emergence, mouth widening with developing horny jaws, progressive tail shortening (autolysis/resorption), and finally, the emergence of a fully formed, lung-breathing adult frog. Each developmental stage is sculpted in raised 3D relief and finished with non-toxic, chip-resistant pigments that highlight external morphology and structural transitions. The board features numbered identification indices paired with an attached laminated reference key card, making it ideal for classroom lecture demonstrations, group self-study, and practical viva-voce assessments. Victor Scientific Co. supplies precision-crafted zoological and biological models nationwide with guaranteed durability and secure packaging.

✹ Key Features

Complete Metamorphic Life Cycle Sequence

Depicts 8 to 11 progressive relief stages illustrating eggs, cleavage, early tadpoles, gill respiration, limb emergence, and adult morphology.

Clear Respiratory & Locomotor Transition

Highlights morphological adaptations including tail fins, external gill filaments, opercular folds, hindlimb development, and tail regression.

High-Definition 3D Relief Detailing

Magnifies minute embryonic and larval features, making small morphological changes easily visible across large classrooms.

Durable Medical-Grade PVC / Fiberglass Build

Cast from high-impact, washable PVC plastic mounted on a finished wooden or heavy-duty polymer baseboard that resists tropical humidity.

Vibrant Biological Color Coding

Finished with non-toxic, fade-resistant pigments that clearly contrast jelly capsules, aquatic larvae, skin pigments, and adult coloration.

Numbered Demonstration Key Card

Features clear numerical callouts stamped beside each developmental stage corresponding to an included laminated reference legend for spot tests.

Wall-Mountable and Benchtop-Ready

Designed with a balanced footprint suitable for demonstration easels or secure wall hanging in school biology and zoology laboratories.

✹ Applications
