Product Description

Hydra Model – Biology Teaching Aid

The Hydra Model on Board is an essential biological teaching aid crafted to demonstrate the external morphology, internal histological layers, and reproductive structures of the freshwater polyp Hydra. Cast from high-density, unbreakable PVC plastic or reinforced fiberglass and mounted securely on a finished demonstration board, this magnified relief model depicts the anatomy of a diploblastic cnidarian. It serves as an essential teaching benchmark across secondary school biology classes (SSC/HSC), college botany/zoology departments, and university biological sciences faculties throughout Bangladesh.

Understanding coelenterate morphology, cellular differentiation, and asexual budding can be difficult for students when relying solely on two-dimensional textbook sketches or delicate whole-mount microscope slides. This physical model resolves that learning barrier by magnifying the organism hundreds of times in longitudinal section (L.S.). Key structural elements—such as the hypostome with oral aperture, whorled hollow tentacles, gastrovascular cavity (coelenteron), ectoderm (epidermis), non-cellular mesoglea, and inner endoderm (gastrodermis)—are distinctly sculpted and color-coded.

In addition to basic digestive and sensory structures, the model clearly showcases typical reproductive organs, including conical testes near the oral end, developing ovaries near the basal disc, and a lateral bud demonstrating asexual budding. The board includes numbered identification points paired with a printed key card, making it ideal for classroom lecture demonstrations, group revisions, and practical viva-voce tests. Victor Scientific Co. supplies durable, hand-painted biological and zoological teaching models nationwide with guaranteed quality and secure packaging.

✹ Key Features

Magnified Longitudinal Section (L.S.) Display

Features a highly enlarged 3D cutaway showing internal anatomical architecture from the oral cone down to the basal pedal disc.

Diploblastic Body Wall Detailing

Clearly differentiates the outer protective epidermis, acellular middle mesoglea layer, and inner nutrient-absorbing gastrodermis.

Complete Organ System Representation

Accurately depicts the hypostome, mouth, gastrovascular cavity (coelenteron), tentacles with nematocyst batteries, testis, ovary, and a developing bud.

Durable, Impact-Resistant Construction

Fabricated from medical-grade PVC plastic and fiberglass mounted on a rigid baseboard that resists cracking, chipping, and tropical humidity.

High-Contrast Hand-Painted Finish

Coated with fade-resistant, non-toxic colors that clearly separate cell layers and tissue types under standard indoor classroom lighting.

Numbered Demonstration Key Card

Features clear numerical callouts stamped beside each anatomical part corresponding to an included reference card for practical assessments.

Wall-Mountable and Benchtop-Ready

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