Predator–prey interactions and defensive adaptations can be queried directly from biological entity data. This example retrieves species based on (i) predator relationships, (ii) observation location constraints, and (iii) anti-predator adaptation traits, and visualizes the resulting food-web structure.

Retrieve and display animal species that list the cheetah as a predator:
