The feet of a gull showing webbed toes. Webbed toes is the common name for syndactyly affecting the feet. It is characterised by the fusion of two or more digits of the feet. This is normal in many birds, such as ducks; amphibians, such as frogs; and mammals, such as kangaroos.he feet of a gull showing webbed toes.

The sporangia produce very tiny spores. Spores are different to seeds. They do not contain plant embryos or food stores. When the sporangia break open, the spores are released and dispersed by the wind.If the spore lands in a suitable environment, it can grow into a tiny plant called a gametophyte.he sporangia produce very tiny spores.

This restricts the airflow around the plant and creates an environment favorable to fungus. High humidity and a few cool nights (68-77 degrees) added to the mix and you've got heaven for fungus. Small circular spots appear on the upper side of the leaf. Septoria usually appears first at the base of the plant. Here, the humidity is the highest and the spores can easily splash up from the soil. The spots have dark edges and a grayish center. In the spot are small black or brownish spots: these are the fungal spores, ready to mature and spread to other plants.
