Differing characteristics of zoochory syndromes include coloured fruits, scented fruits, and different textures for different animals. Some fruits with hook , bristles and sticky surface attach to the fur, hair , feather of some animals that can be dispersed to other places. Compared to mammal‐dispersed species, bird‐dispersed fruits show stronger phenotypic integration in morphological traits, probably as a result of their strong selection on fruit/seed size and mass due to their limited ability to exploit fruits larger than their gape width (Valido, Schaefer, & Jordano, 2011). The study found the fruit-bearing plants had evolved to cater to the visual capabilities of the main seed-dispersing animals in each place.
