If you follow Dnevnik to get the most important news and stories, now your children can too. Every Monday “Detski Dnevnik” reprints the text of the site “Look – News about children’s language”informing and explaining current events from the nation and the world in a format that young readers can understand.
These articles are a suitable way for children to learn about what is happening in society and a good reason to have a conversation (why not an argument) about these issues in the family. Due to the older readership targeted by the column, the editor has decided to close the column to comments.
“look” It is also part of a platform to promote reading and literacy among children. nigovisht.bgYou can find more children’s language news at hereand more about “Library” – here.
Why are we talking about this?
Because it is also in the Black Sea.
Summer dates are a good thing. But not all of them! Some summer dates start like this:
You are swimming peacefully in the warm, clear water. Water is running down your nose. You stretch out your foot to touch the bottom and… you get pricked by a thorn! Where do you get the thorns in the sea?
Wrong. That’s not a thorn. You stepped on a sea urchin. A sea…what? Are there really hedgehogs underwater? Oh yeah. And sea cucumbers, sea cats, sea horses, and of course sea lions…all of these marine animals have no relation to land cucumbers, cats, horses, and lions (cucumbers aren’t even animals!), they just look like…something. People have big imaginations.
Back to the sea urchin. You can probably guess what it looks like to its fellow Earthlings! Well, yes, on the thorns. As you might guess, the spines help the sea urchin protect itself from its enemies. Like people who want to step on it!
Sitting on your butt and having a big foot on you can be very unpleasant. You have to protect yourself!
Beyond that, however, the spines help the urchin move along.
Their tube-like legs often have suction cups on the end, which helps them do this. A close relative of the sea urchin, the sea star (another marine animal with an unusual name!) is also very similar.
The tube feet and spines also help the sea urchin catch food. Don’t stress! He eats plants, so he’s unlikely to enjoy your thumb for breakfast.
Let’s move on to trivia. Sea urchins (unlike land urchins) are invertebrates. In other words, they don’t have a spine. However, they do have an internal skeleton. The spikes are attached to it.
How big are these sea urchins? Some are as small as the margins of a notebook. Others are longer than your Man and Nature textbook! Their colors vary, too – from almost red to black. In fact, there are many species of sea urchins in the world – and this is no surprise, as they are found in almost all oceans – except the Arctic Ocean!
You must be thinking: Hey, such a strange animal must be a very ancient species! And you are absolutely right. The ancestors of today’s sea urchins also swam in prehistoric oceans. The Sofia Paleontological Museum can prove this. There you will find many sea urchin fossils.
Back to the leg stung by the sea urchin. That must have hurt!
Wait a while for the pain to subside, then have your parents wash the area and try to remove the splinter with tweezers. You can also ask the pharmacy for a suitable ointment. If you are unable to remove the splinter, it is best to see a doctor.
How to protect yourself from sea urchins? Well, you will rarely see them in the Black Sea. But if you know some places where you go swimming, wear special swimming shoes. Happy swimming!
