Staff at Houston Zoo released more than one million Houston toad eggs in a protected habit as part of a species recovery program, recent footage shows.

The Houston toad, an endangered species, is a small, brown amphibian. The toad was typically located in more than a dozen counties but can only be found only in a narrow stretch of east-central Texas, Houston Zoo said.

The eggs were released as art of a conservation effort by Houston Zoo, Texas Parks and Wildlife, the US Fish and Wildlife Service, and staff at Dallas Zoo and Fort Worth Zoo.

Staff counted and documented the eggs using a automated software and released them in a protected habitat in Bastrop County, Texas. Credit: Houston Zoo via Storyful
