Zebrafish Models in Toxicology and Disease Studies

Area of Science:

• Ichthyology
• Aquatic Biology
• Zoology

Background:

• The zebrafish (Danio rerio), also known as Brachydanio rerio, is a small tropical freshwater fish.
• First described by Francis Hamilton in 1822 from the Ganges River.

Discussion:

• The species is now widely distributed across the Great Himalayan region of Southeast Asia.
• Its ecological adaptability contributes to its broad geographic range.

Key Insights:

• Danio rerio exhibits significant adaptability to various freshwater environments.
• Historical records trace the initial scientific description of the zebrafish to the early 19th century.

Outlook:

• Further research can explore the genetic and environmental factors driving zebrafish's widespread distribution.
• Understanding the ecological role of Danio rerio in Southeast Asian freshwater ecosystems is crucial.
