Can you match the state with the marine mammal "symbol"?

Can you match the state with the marine mammal “symbol”?

Download the pdf here. I’ll post the answers next Monday. First person to comment with the correct answers (here or on Facebook) I’ll send a copy of the Smithsonian’s Whales, Dolphins and Porpoises (Flexibound).

Also, if I’ve missed a state with a marine mammal “symbol”, please don’t hesitate to let me know.

Celebrity dolphins may also give their kids bizarre names

Dolphinclicks_BCSInteresting details on how dolphins communicate came out this week. 2006 brought us research that unique dolphin clicks can be interpreted to include a name and some basic information about the individual marine mammal (see image). But even more recently, research uncovered that dolphins call each other by name, especially when they’ve become separated from one another. It was stated that other than humans dolphins are the only animals known to do this!

Are manatees and elephants related?

It might be very difficult to imagine, but manatees (also known as ‘sea cows’) share a common ancestor with elephants which might come as a surprise if you thought manatees shared a common ancestor with other marine mammals such as dolphins, whales, or sea lions. Here are 10 facts that link manatees and elephants as long-lost relatives.

1. Scientifically, manatees and elephants are classified as subungulates. Other mammals in the Subungulata superorder are hyraxes and aardvarks.
2.Manatees and elephants have an uncommon-shaped heart that is spherical. To compare, most mammals have a single-pointed tip at the base (i.e., “heart”—shaped).
3. The West Indian and West African manatee have three or four fingernail-like structures on the tip of their flippers, just like that of the toenails on the feet of elephants.
4. Manatees and elephants both have a thick, gray skin with very sparse hair.
5. Manatees and elephants have molars which move toward the front of the mouth, eventually break off, and are restored by those at the rear. Elephants have a limited number while manatees are never-ending.
6. Manatees have two incisors that bear a resemblance to elephant tusks.
7. Manatees use their large, flexible muscular lips to break apart vegetation in the water and skillfully steer food to their mouths. This is very similar to the action of the elephant eating with his trunk.
8. Manatees and elephants are herbivores. Manatees tend to feast on sea grass and freshwater plants and consume up to 100-150 pounds a day. Elephants tend to feast on small plants, bushes, fruit, twigs, tree bark, and roots and consume up to 330-375 pounds a day.
9. Male manatees and elephants are known as bulls. Female manatees and elephants are known as cows. Young manatees and elephants are known as calves.
10. Manatees and elephants are both endangered. Their numbers have dropped due in a large part to human activities.
