I hope all of you are wearing your swim trunks today because we are going to play in the deep blue sea.\u00a0 The good news is, you can pretty much go to the nearest ocean and find today’s animal, the Sea Urchin.\u00a0 Unfortunately, I will need to head south since they aren’t typically found this far north (and there are no oceans around here).\u00a0 When you are out splashing around in the ocean take a look around because you may just find a Sea Urchin.\u00a0 They can be found in shallow or deep waters and they usually hang out around coral reefs.\u00a0 One more reason to explore the amazing coral reefs.<\/p>\n

So what exactly is a Sea Urchin?\u00a0 Well, they are typically small, globular and spiny, however, this description may not be incredibly accurate since there are over 200 species of Sea Urchin. With that many species, you can imagine that they come in various shapes, sizes and colours.\u00a0 For example some may be spiny while others have a hard shell.\u00a0 I guess you could say Sea Urchins are like a box of chocolates, you never know what you are going to get.<\/p>\n

Sea Urchins are definitely built differently than most other animals on our planet.\u00a0 For starters they have five paired rows of little tube feet, which are usually found among their protective spines.\u00a0 Not only do the feet of the Sea Urchin help them move but the “suckers” on their feet help them catch their prey as well as keep them attached to the ocean floor.\u00a0 Not only do their spines conceal these awesome tube feet but they also hide these nifty little\u00a0 claw-like structures.\u00a0 These little “claws”, also called pedicellarines, offer additional protection for the Sea Urchin as they are capable of stinging would-be predators.\u00a0 These stingers are also useful in obtaining food and ensuring the Sea Urchin stays clean.<\/p>\n

The odd anatomy doesn’t stop there.\u00a0 The mouth of the Sea Urchin which is also known as “Aristotles Lantern” can actually be found in the middle of this animal’s underside.\u00a0 It seems like a weird place to put a mouth but what do I know?\u00a0 Like other echinoderms the Sea Urchin doesn’t actually have a brain and just relies on their water vascular systems, which basically works like are circulatory system.\u00a0 Well it works a little differently but you get the idea.<\/p>\n

Sea Urchin Fast Fact – <\/strong>The Red Sea Urchin is among the longest living creatures on earth.\u00a0 They have been known to get as old as 200 years.\u00a0 Not too shabby for an animal without a brain.<\/p>\n
