0:00.0	Hi, it's Elise Hugh with Ted Talks Daily.
0:06.2	Ted is on vacation this week.
0:07.9	So here's something a little different.
0:09.8	TEDx Shorts, a podcast that shares a quick new idea each day.
0:13.9	Did you know that baby fish and other ocean animals like clams, oysters and crabs,
0:19.3	use sound to select their best habitats.
0:22.3	It's all about listening to the soundscapes of the ocean.
0:26.2	Hear all about it in this episode,
0:28.0	and if you like what you hear,

0:49.3	We can hear which species live there.
0:51.4	We realize that the fish at sea are doing much what we would do if we were

0:59.2	suburbs that we might want to live in. We think fish can do the same thing by listening to their
1:04.6	environment and choosing where they want to live. We now know that reefs all sound different.
1:10.3	They have signature sounds. Babyfish can select
1:12.6	the best habitat for their kind by using sound. And amazingly, it turns out so can many other
1:19.5	animals on coral reefs. Crabbs, lobsters, clams, oysters, even corals themselves. Now I'm going to take you to a few places that we've worked.
1:29.7	This is Balakasag, which is a marine protected area in the Philippines. You can see it's full of life.
