Algún día me decidiré por algún tema en particular para mi tumblr, hasta entonces tendréis que conformaros con un popurrí de anime, manga, historia, arte e idioteces de todo tipo. Y muchos gatos.
I wanted to celebrate being halfway through the photos by offering five of them as a free printable download (available here). Enjoy, and spread the word!
*edit: it has come to my attention that in British English (which I use) there is a distinction between “turtle” and “tortoise”, while in American English all these guys fall under the “turtle” category. Oh well. The more you know!
It is difficult to imagine corals as animals. They are colorful and immobile. They grows like fungus and sometimes looks like a strange alien plant.
The corals are cnidarians just like jellyfishes. Yes, they are closely related with the jellies !
We know that a jellyfish can sting. Like them some corals can also have mild stings. These species of corals can catch small fishes and sea invertebrates to eat by using their tiny poison spears.
Actually, a coral is a colony of thousands of small polyps. These polyps are joined with each other by exoskeletons.
There are many types of corals. All of these can be grouped into two main categories - hard and soft coral. The hard corals have a hard, rock like exoskeleton made of calcium carbonate. They are less colorful than their soft cousins. Brain coral is a type of hard coral.
The soft coral has a soft exoskeleton. They can move and is quiet flexible.
Feel free to give your opinions or ask anything regarding corals.
