1. Glass Frog: The glass frog is a fascinating amphibian known for its unique transparent skin, which allows observers to see its internal organs. These intriguing creatures belong to the family Centrolenidae and are primarily found in Central and South America, inhabiting rainforests, cloud forests, and tropical montane regions. With their translucent bodies and vibrant green colouration, glass frogs have captured the curiosity of researchers and nature enthusiasts alike.

The name “glass frog” is derived from their remarkable skin, which resembles glass or frosted glass due to its translucency. The skin is thin and delicate, allowing light to pass through and revealing intricate details of their anatomy. The extent of transparency can vary among species, with some appearing almost entirely see-through, while others have more opaque areas on their bodies.

Glass frogs typically have a vibrant lime green colour on their dorsal surfaces, providing excellent camouflage against the lush green foliage they inhabit. This green pigmentation helps them blend seamlessly with their surroundings, making them difficult for predators to spot. Some species may also exhibit yellow, brown, or reddish markings on their bodies.

The most striking feature of glass frogs is undoubtedly their ventral surface, which showcases their internal organs. This unique adaptation serves various purposes, including communication, courtship, and protection. Males often use their transparent skin to display their reproductive organs, such as testes and vocal sacs, during mating rituals. This visual display allows potential mates to assess their suitability as partners.

Glass frogs possess a semi-arboreal lifestyle, spending much of their time in the understory vegetation near streams, rivers, and wetlands. They are primarily nocturnal creatures, becoming more active during the night when they search for insects, spiders, and other small invertebrates to feed on. Their long, slender limbs and adhesive toe pads enable them to climb and cling to leaves and branches, granting them access to their prey and protection from ground-dwelling predators.

Reproduction in glass frogs is an intriguing process. Males typically initiate courtship by vocalizing from exposed perches, such as leaves hanging over water bodies. Their vocal sacs amplify their calls, which are unique to each species. Females are attracted to the calls and approach the males for mating. Once a suitable partner is found, the female lays her eggs on the underside of leaves, often above running water. This strategic placement helps protect the eggs from terrestrial predators.

After laying the eggs, the male glass frog takes on the responsibility of guarding them. He remains vigilant, periodically moistening the eggs with water from his bladder to prevent them from drying out. This behaviour continues until the eggs hatch into tadpoles, which then drop into the water below. The tadpoles undergo metamorphosis over a few weeks or months, gradually developing their transparent skin and eventually transitioning into miniature versions of their adult forms.

While glass frogs have captivated the interest of researchers, there is still much to discover about their biology and behaviour. Studies have focused on understanding the mechanisms behind their transparent skin and its role in their ecological interactions. Additionally, ongoing research seeks to determine the conservation status of different glass frog species, as many face threats from habitat destruction and climate change.

The life cycle of the Glasswing butterfly follows the typical pattern of other butterflies. The female butterfly lays her eggs on the undersides of leaves, usually selecting host plants that provide food for the emerging caterpillars. The caterpillars undergo several moults as they grow, shedding their old skin to accommodate their increasing size. After the final moult, they form a chrysalis, within which the transformation from caterpillar to butterfly occurs.

The duration of the pupal stage varies depending on environmental conditions and species. Once the transformation is complete, the adult Glasswing butterfly emerges from the chrysalis. Its wings, initially crinkled and soft, gradually expand and harden, ready for flight. The adult butterflies then engage in courtship rituals, with the males engaging in aerial displays to attract females.

While the Glasswing butterfly’s transparent wings offer protection and beauty, they also present a challenge. The delicate nature of the wings makes them vulnerable to damage, reducing their lifespan. Predators, such as birds and spiders, pose a constant threat.
