They are considered animals, predatory freshwaters microorgranisms; they can be found in ponds, lakek and other slow-moving waters. They feed on different creatures (e.g. insect larvae and small crustaceans) and they die only because of injuries, diseases, starvation or being eaten. '''Interesting feature''': they can develop a mutualistic relationship with algae > the hydra feed on things that would otherwise predate on the algae, while the algae produce photosynthetic compounds that can be utilized as a food source by the hydra. ♥️ | They are considered animals, predatory freshwaters microorgranisms; they can be found in ponds, lakek and other slow-moving waters.
