Animals with radial symmetry get information
from their environment in a different way than animals with bilateral symmetry. Radially symmetric animals, such as sea anemones or starfish, have multiple limbs or tentacles extending outward from a central point. These limbs can be organized in a circular or pentaradial pattern.
As these animals do not have a distinct front or back, they receive information from all directions simultaneously. Their sensory organs, like eyespots or touch-sensitive cells, are distributed throughout their body surface. This allows them to detect stimuli from any direction, such as changes in light, water movement, or the presence of prey or predators.
In contrast, animals with bilateral symmetry, like humans or fish, have a distinct front and back, and tend to have specialized sensory organs concentrated at the front. They usually have a well-defined head with eyes and other sense organs that provide more focused information about their environment in a forward-facing direction.
Overall, the different body plans and symmetry types of animals determine how they receive and process information from their surroundings.
