Gasopod

A slow-moving lifeform, and one of the larger herbivores on the planet. Providing a substantial meal to would-be predators, the gasopod protects its domain by filling the surrounding water with poisonous and corrosive pods whose contents dissolve even synthetic fibers. 1. Filtration System: Thick, non-reactive skin and multiple gill layers render this creature impervious to the noxious acid clouds it produces. 2. Algae Gland: A bulbous, sack-like appendage on the rear end. A luminescent yellow algae grows inside the sack and produces the poisonous compound. Abdominal muscles can contract, causing the algae gland to emit the noxious compound into the surrounding water. 3. Large Pelvic Fins: Capable of powerful movement through the water when moving in small herds. 4. Behavior: Gasopods appear to be social in nature, and may even use their emissions in their relationship rituals. Their audible calls are likely signifiers of nearby threats, or food sources. Assessment: Approach with caution - Acidic pods may be retrieved and re-purposed
