TRUE: Electric eels are actually fish that breathe by gulping air from the surface.
TRUE: Some fish start their lives as males but grow into females.
FALSE: Despite their unusual shape, sunfish are some of the sea’s strongest swimmers

Sunfish, or molas, do not have a swim bladder and steer themselves by squirting a jet of water out of their mouth or gills. For this reason, sunfish maneuver poorly and are not strong swimmers. Have you ever seen a sunfish before? Where did you see it? And who’s surprised to learn that electric eels aren’t actually eels?

TRUE: Ancient Greek dentists used the venom from the stingray’s spine as anesthetic.
TRUE: Doctors once used Asian carp as a test for pregnancy.
FALSE: Amazon explorers took a medicine derived from coral to fight off malaria.

Coral has not been used to fight off malaria, but that doesn’t mean it doesn’t have real medicinal promise. In fact, coral reefs are often called “the medicine cabinet of the 21st century.” Coral reef-based medicines are being developed to treat cancer, arthritis, heart disease, viruses, and more–yet another reason to protect these delicate ecosystems. You can learn more about why coral reefs are so important from NOAA here.

Pearls of Wisdom: Sharks Answer http://blog.oceanconservancy.org/2012/05/27/pearls-of-wisdom-sharks-answer/ http://blog.oceanconservancy.org/2012/05/27/pearls-of-wisdom-sharks-answer/#comments Mon, 28 May 2012 00:00:35 +0000 Guest Blogger http://blog.oceanconservancy.org/?p=808

TRUE: One of the rarest sharks is called a megamouth shark.
TRUE: Some sharks can increase their size by swallowing large amounts of water.
FALSE: Like dolphins, sharks do not have scales.

Sharks are covered with small, tooth-like scales called dermal denticles. Sharks feel smooth to the touch because their scales are designed to reduce drag. Megamouth sharks and swell sharks are both real animals! Megamouths sound scary, but they’re filter feeders and prefer plankton. Swell sharks, as their name implies, can swell up to twice their normal body size just by swallowing water. What’s your favorite shark?

Pearls of Wisdom – Walruses Answer http://blog.oceanconservancy.org/2012/05/20/pearls-of-wisdom-walruses-answer/ http://blog.oceanconservancy.org/2012/05/20/pearls-of-wisdom-walruses-answer/#comments Mon, 21 May 2012 01:12:01 +0000 Guest Blogger http://blog.oceanconservancy.org/?p=706

TRUE: Both male and female walruses have extended tusks.
TRUE: Walruses can slow their heartbeat while diving underwater to keep warm.
FALSE: To maximize the ratio of insulating blubber to body size, walruses have a lower blood volume than most land animals their size.

Because walruses spend so much time underwater, they store oxygen in their blood and muscles. They actually have an enormous blood volume–two to three times as much as other land animals their size. Do you know any interesting ways other animals have adapted to their surroundings?
