The Brno Zoo has achieved a significant milestone, successfully breeding the San Martin Island rattlesnake—a first for any Czech zoo. This exotic snake, native to North America, is notable for its unusual defense mechanism: it both hisses and screams when threatened. The breeding program represents a considerable success for the zoo’s herpetological team and contributes to the conservation of this species. The newly hatched rattlesnakes are currently being carefully monitored by zoo staff. This birth is a rare event, highlighting the zoo’s commitment to the preservation of biodiversity. Experts believe this accomplishment will aid in future research and breeding programs for this unique reptile. The zoo is proud to contribute to the species' survival.
