During our January 17 LATO Lunch Club, Santa Margarita School nature detectives had fun learning about frog biology and ecology with professional biologist and frog lover Brooke Langle.

Brooke was assisted by Cal Poly wildlife biology senior and LATO docent Keelan Dann, as well as Cal Poly Science Senior Project student Ashley Beeman, LATO docent Mike Klatt, and Oak Ambassador Chris Lawson. Ms. Beeman prepared the questions below to help us review what we learned. Thanks to Ms. Langle and all who helped with this month’s presentation.

[toggle title=”One more comment from Brooke and where to find more cool information about amphibians: “]I think one really amazing feature I didn’t focus on or discuss is the ability for frogs to breathe under water – they still breathe air on the surface, but can also conduct gas exchange in the water when they need to stay under for a period of time or in a hibernation mode.
