Coloured SEM of a marsh slug, Agriolimax laevis
Marsh slug. Coloured scanning electron micrograph (SEM) of the head of a garden or marsh slug (Agriolimax laevis). At centre left is the mantle which is a fold of skin which covers the internal organs. The optical tentacles (top centre & top right corner) can be seen just above the sensory tentacles (upper centre & upper right). The mouth (centre right) includes a tooth covered tongue (radula, not seen here) which it uses like a rasp to grate food. Slugs, unlike snails, have no shell which makes slugs far more agile and hence are a greater threat to crops and plants. This species of slug is often found in gardens and crop fields.

EDITORS COMMENTS
This print showcases the intricate details of a marsh slug, Agriolimax laevis, captured through a colored scanning electron microscope (SEM). The image focuses on the slug's head, revealing fascinating features that contribute to its survival and behavior. At the center left of the image lies the mantle, a protective fold of skin enveloping the internal organs. Above it, we can observe two sets of tentacles. The optical tentacles are positioned at the top center and top right corners while just below them are sensory tentacles. These specialized appendages play crucial roles in detecting their surroundings. Moving towards the center right, we encounter an intriguing sight—the mouth of this marsh slug. Here lies a tooth-covered tongue known as a radula (not visible in this image), which acts like a rasp to grate food for consumption. Unlike snails, these slugs lack shells but compensate with enhanced agility. This absence allows them to navigate swiftly across various terrains and poses significant threats to crops and plants—making them notorious garden pests. Agriolimax laevis is commonly found in gardens and crop fields where they can cause considerable damage if left unchecked. This remarkable species belongs to mollusks' diverse family called gastropods—a group encompassing animals such as snails and slugs. With magnifications ranging from x14 at 7x5cm size up to x37 at 7x5ins size, this SEM photograph provides us with an extraordinary glimpse into nature's microscopic
