Which larger animals have not been reported as pollinators in some species ?

Options

A. Tree-dwelling rodents
B. Some primates (lemurs)
C. Gecko lizard and garden lizard
D. Shrews

Answer

**Step-by-Step Solution:**

1. **Understanding Pollinators**: Pollinators are organisms that help in the transfer of pollen from the male part (anthers) of a flower to the female part (stigma) of the same or another flower, facilitating fertilization.

2. **Analyzing the Options**:
- **Tree-dwelling Rodents**: These rodents live in trees and have adaptations that allow them to consume plant material. They can carry pollen grains on their fur or bodies while feeding on flowers, thus acting as pollinators.

- **Lemurs**: These primates are known to interact with flowers by using their hands to open them and their long snouts to access nectar. Pollen grains can stick to their fur, allowing them to transfer pollen between flowers, making them effective pollinators.

- **Gecko Lizard and Garden Lizard**: Lizards are primarily attracted to the nectar of flowers but do not have the adaptations necessary for effective pollen transfer. They do not actively collect or transport pollen, thus they are not considered pollinators.

- **Shrews**: These small mammals visit multiple flowers and can carry pollen grains on their fur, contributing to pollination.

3. **Conclusion**: Among the options provided, the gecko lizard and garden lizard are the larger animals that have not been reported as pollinators in some species, as they do not effectively transfer pollen.

**Final Answer**: Gecko lizard and garden lizard.
