マナティは怪我をしたマナティを保護しているので、みんなひれが半分なかったり、大きな傷があったりする。たあくんはゆっくり動くマナティが息をする為に水面に上がるときに、水面を走るボートにぶつかり、ボートのスクリューにぶつかり怪我をしてしまう事を学んだ。さらに、マナティとゾウの祖先は一緒で、マナティの足ひれが、ゾウの足にそっくりなのを学んだ。
セイウチは、彼らの大きな牙のこと。シーワールドにいたセイウチには牙が無かった。普通、オスにもメスにも牙がある。この牙は頭蓋骨と繋がっているらしく、虫歯になるとばい菌が脳にいってしまい、危険なのだそう。で、シーワールドにいるセイウチは虫歯になった牙は切り取ってしまうのだそうですよ。
Taka brought the book about sea animal from school library. He told me he wants to see some of them not just pictures and he made a copy. So we went to Sea World to see those animals but he picked really rare ones. We enjoyed genuine aquarium even though we could not fined any animal Taka wanted to see. We saw swimming sea otters and dolphin, touched stingrays, saw moray eels, touched starfish, sea urchin and anemone, checked World of the sea Aquarium, checked Aquarium de la Mer, checked freshwater Aquarium, saw sharks, saw Manatees and checked Wild Arctic Interaction. This time my boys eagerly checked Manatee and Walrus and Taka learned a lot about them.
Manatee and elephant have a same ancestor. So Manatee's front fin and elephant's legs are look-alike. Also Taka learned about Manatee gets hurt by boat when they come to the surface of the water when they breath.
Walrus (both male and female) have two big tusk. But what we saw was Walrus with no tusk. Walrus' tusks are connected with their skull. When the tusk has a cavity, the germ goes to brain and it is very dangerous for them. So that walrus had cavity and tusks are surgically removed.
