Sensory cells in the fish lateral line organ are similar to human inner ear sensory cells, leading to the use of zebrafish for ear drug toxicity testing.

“And fish, for example, we talked about fish and other species that live in the seas and oceans. They have this lateral line organ along their side that detects vibration, and it's very similar to the sensory cells in the inner ear to the point that we sometimes use, for example, zebra fish as animal models because they are transparent.”
