{QTtext}{timescale:30}{font:Arial}{width:240}{size:10}{justify:center} [00:00:00.02] [00:00:04.28] NARRATOR: Sea horses, like these [00:00:06.29] at the National Aquarium in Baltimore's new exhibit, [00:00:10.05] never cease to astonish. [00:00:12.26] Even stranger than their bizarre appearance [00:00:15.17] is the startling observation that the smooth-bellied males [00:00:18.28] get pregnant and give birth. [00:00:21.14] [00:00:25.01] It's just one of the puzzles presented to scientists [00:00:27.24] trying to understand and save sea horses. [00:00:31.00] [00:00:36.29] One species of sea horse is native to the Chesapeake Bay. [00:00:41.06] [00:00:43.17] At the Calvert Marine Museum in Solomons, Maryland, [00:00:47.04] aquarist Carin Stringer is charting unknown waters [00:00:50.20] in her research on this species. [00:00:54.01] STRINGER: Hippocampus erectus is the only species of sea horse [00:00:57.15] in the Chesapeake Bay, [00:00:59.02] and nobody knows much about it at all. [00:01:01.21] They're hard to raise. [00:01:03.06] Nobody has, to this point, published anything [00:01:06.14] about raising the species or has any good data on it, [00:01:10.12] and we'll be the first ones if we get any good information. [00:01:14.16] [00:01:17.06] I think people are fascinated with sea horses [00:01:19.26] because they have a head that looks like a horse, [00:01:22.24] they have a tail that can wrap around things like a monkey, [00:01:26.23] and they have these eyes that move independently [00:01:29.02] like chameleons do. [00:01:30.27] And they also share with chameleons [00:01:32.19] the fact that they can change their color readily. [00:01:35.24] Plus, they move so gracefully through the water. [00:01:38.23] "Hippocampus," their species name, [00:01:40.23] actually means "sea monster." [00:01:44.03] NARRATOR: This species of sea horse is also known [00:01:46.15] as the lined or northern sea horse. [00:01:49.12] Its range in North America [00:01:51.03] is thought to lie along the Atlantic [00:01:53.01] from Canada to Florida. [00:01:54.18] [00:02:04.10]
