How to compare two organisms
Choose two species and trace their closest shared group. Then compare a trait with the same definition on each side. Check the units, life stage and context before interpreting a measurement or range.
Missing data means that the collection lacks a sourced value. Where a characteristic does not apply to a lineage, the comparison labels it separately. Open the two profiles for context and follow their sources before drawing a conclusion.

Compare their characteristics
| Trait | Dictyostelium discoideum | Tiger |
|---|---|---|
| Nutrition | Data unavailable | Carnivorous Source ↗ |
| Social organization | Not applicable | Generally solitary Source ↗ |
| Physical traits | Feeding cells are amoeboid. Developing aggregates, migrating slugs and stalked fruiting bodies have very different appearances. | Dark stripes break up the tiger’s outline. Stripe patterns vary from one individual to another. |
| Habitat and range | Soil-associated and decaying-organic-matter environments provide bacterial food and surfaces for development. | Tigers live in varied habitats, including tropical forests, mangrove swamps and temperate forest. |
| Diet and nutrition | Vegetative amoebae ingest bacteria. Resource depletion changes development rather than simply producing a smaller feeding cell. | Tigers mainly hunt large mammals, including deer and wild pigs. |
| Behavior and activity | Chemical signaling coordinates aggregation and collective movement during the developmental response to starvation. | A tiger usually hunts by stalking its prey and attacking at close range. A tiger can communicate without meeting another tiger directly. Scratches and scent marks leave information at places another animal may visit later. In addition to stalking on land, tigers can swim well and have been observed hunting in water. |
| Reproduction and life cycle | Feeding cells multiply individually. Aggregation leads to a multicellular stage and then stalk and spore differentiation; spores can restart feeding growth. | Young tigers stay with their mother while developing the skills needed to take prey. This prolonged period of dependence is consistent with an adult life that is generally solitary. A photograph of a female with cubs therefore describes an important life stage rather than a permanent social group. |
| Geographic distribution | Authenticated environmental isolates and laboratory strains have distinct collection histories. Research use is not a complete map of wild occurrence. | Data unavailable |
| Ecological role | Its transition between independently feeding cells and multicellular development makes environmental conditions central to its biology. The genome study identified many systems for producing and exporting small molecules, providing a genetic framework for investigating how an amoeba coordinates behavior with other cells. | Data unavailable |
| Distinctive adaptations | The transition between feeding independence and coordinated dispersal is a distinctive response to changing resource conditions. | Individual stripe patterns have practical value to field researchers. Paired cameras can photograph the sides of a passing tiger, and repeated images of the same pattern can identify the same animal. A sequence of detections across sampling locations can support a population estimate. |
