Try to picture a tiny, transparent crustacean that looks like a hybrid of a centipede and a horseshoe crab with a zillion writhing legs. While they’re not likely to win any beauty contests, triops are impressive little critters. The genus Triops has been around for as long as 300 million years—that’s about 200 million years older than T. Rex—making them the oldest known animals on the planet. Here are some other fun facts about these resilient creatures. 1. TRIOPS ARE OFTEN CALLED "LIVING FOSSILS,” BUT THAT'S A MISNOMER. Commonly known as tadpole shrimp, they appear to be almost identical physically to their fossilized ancestors. But appearances can be deceiving. Recent research shows that their DNA and reproductive techniques are constantly …show more content…
THEY CAN HAVE AS MANY AS 140 (SURPRISINGLY MULTIPURPOSE) LEGS. What what they do with them is far more impressive than walking or swimming. Some legs act as antennae that help them find food, while others create a water current to direct food toward their mouth. Females have capsules on some of their legs to carry eggs. Some triops have lobe or leaf-like extensions on their legs that function similarly to gills, allowing them to breathe. 6.THEY EAT A LOT—INCLUDING EACH OTHER. iStock Triops have a varied diet, from mosquito larvae to aquatic plants and tiny invertebrates to, um, other triops. Yes, to support their rapid growth, larger triops will cannibalize smaller ones if food supplies run low. Hey, when your home is perpetually in danger of drying up, you have to eat as much as you can so you can grow and breed before it’s too late. 7. THEY GROW QUICKLY—AND THAT CAN BE DEADLY. Many reaching maturity in one to two weeks—but their exoskeletons do not. That requires them to molt regularly as they outgrow their exoskeletons. Young triops grow so quickly that molting is a daily experience, and a dangerous one: They can die if they don’t successfully shed the old exoskeleton. 8. TRIOPS EGGS CAN LAY DORMANT FOR DECADES, AND THEN HATCH IN …show more content…
These cysts allow triops to move into new territory by hitching a ride with some pretty far-out modes of transportation, including inside migrating birds and in the feet and poop of animals that pick them up from puddles and pools. 9. THEY CAN SURVIVE IN OUTER SPACE FOR 18 MONTHS. Tests on the International Space Station (ISS) prove this hardiness. Those findings led to a NASA high school experiment last year that sent Triops Longicaudatus back to the ISS to test whether it could be grown in space and serve as a high-protein food source for astronauts on future long-term missions. 10. CHARMED? YOU CAN HAVE YOUR OWN! There is a wide assortment of triops starter kits out there to choose from. They’re low-commitment, too: Triops only live for 1–3 months (less if they eat each other). And when one batch dies out, you can dry out the soil or sand in the tank and transfer it to fresh water. If resting eggs are in the sand, with the proper care, you'll soon have another group of

In the lab the isopods were observed in a way to where behavior and structures could be properly recorded. The isopods were revealed to two dissimilar scenarios, normal temperature water vs. warm temperature water, to calculate which environment was most preferred. In each distinct scenario ten isopods were placed ten a choice chamber, one side being normal temperature (26.7celsius) and the other being warm temperature (43.3 celsius) , and observed for a total of ten minutes with thirty second intervals which was when we recorded our observations. After observations, it was seen that normal conditions was the most preferred environment by the isopods. In the scenario the Isopods exhibited taxis behavior, which is behavior caused by factors such as light, temperature, water and such. Nothing physical, but rather environmental.
Adult bearded dragons average 15 to 24 inches in length, while hatchlings are between 3 to 4 inches at birth. Young dragons grow fast and are sexually mature by one year of age. Juvenile beardeds usually start showing their coloration by two months of age. The initial cost of starting a habitat and establishing a food source colony is the most expensive part of breeding Bearded Dragons. The cage itself should be a terrarium large enough for two full-grown Bearded Dragons.
There is no doubt that arthropods are an extremely successful group of animals, with an estimated 5-10 million species worldwide[1], and this can be attributed to having an exoskeleton; it provides many benefits, such as protection from parasitism and other threats. However, one major disadvantage of having an exoskeleton is the limitations that an inelastic cuticle can place on growth. The exoskeleton provides protection, but when freshly moulted the animal is soft and vulnerable, as well as having limited mobility and use of appendages; many seek shelter before moulting[2]. There are similarities and differences between the moult cycles of all the arthropods, however only crustaceans and insects will be discussed here.
Many students who are enrolled in FFA are already heading in the right direction to a bright future. FFA has many career benefits within the program. Any of the career development events (CDE’s) have something that will tie to a career in agriculture or to a career of other sorts. According to the National FFA Organization, “FFA members embrace concepts taught in agricultural science classrooms nationwide, build valuable skills through hands-on experiential learning and each year demonstrate their proficiency in competitions based on real-world agricultural skills”(“Statistics”). There are so many careers that tie into FFA, and many of them have to do with agriculture. Not every career that has to do with agriculture is about farming. There are so many different aspects of the agriculture industry that many people never think twice about. Most people are not interested in agriculture because they think it is just about farming or
Before tetrapods existed, all vertebrates were confined to living in aquatic habitats. The only animals that lived on land were arthropods. Through natural adaptations, the fish developed into amphibians. This colossal stage of change made necessary the evolution of new ways of breathing, locomotion, and reproduction. Paleontologists needed to understand how this transition took place. If the changes in anatomy of the fish developed on land, then they served the same purposes they serve today, such as walking. But what advantages would those same body parts give to the aquatic creatures still living in water? This is one of the questions the scientists are asking themselves. There have been a few hypotheses on this matter. The most recent one states that the transformations of the aquatic creatures happened underwater in order to help them survive. This time period is very difficult to study because there is a very small amount of fossils preserved. A...
Do you ever look at the sky? When the sun makes a pink hue inof the sky and you think to yourself that nothing could go wrong. What if I told you that you could never see that great big ball of gas ever again? There is a story about a hero who saved the world. This is how it begins.
The Triceratops (figure 1) was and herbivore that lived in the late Cretaceous period, which was around 125 million years ago. The Triceratops existed at least 66 million years ago. It was a Rhinoceros-like dinosaur that had a sturdy body structure. It had four legs, three horns, and big eyes. Triceratopses were very complex.

You probably think horseshoe crabs are crustaceans, but you’d be wrong. They actually aren’t crabs at all, and there’s more about the horseshoe crab that you wouldn’t believe. This weird-looking marine animal survived two mass extinctions and lived in the Ordovician Period.
Crustacea is a large subphylum of Arthropoda, consisting of almost 52 000 described species, including animals like crabs, lobsters, shrimp and barnacles. The majority of these are aquatic, living in marine or fresh water environments, though some have adapted to living on land like some crabs and woodlice. Most crustaceans are relatively small, though there are some exceptions. All of them have a hard, strong exoskeleton, divided into two parts, which has to be shed in order to allow the animal itself to grow. They have a large circulation system, where blood is pumped around the body by the heart. Only some crustaceans have sexes separate, and those that are usually mate seasonally and lay eggs. The study of Crustacea is called carcinology.
1906 was the start of the longstanding feud that later resulted in World War one. In 1914, the war finally broke out between the Triple Alliance and the Triple Entente. The Triple Alliance consisted of Germany, Austria- Hungary and Italy. Britain, France, Russia and Australia (Later on America joined) were then known as the Triple Entente, which was run by the British Empire. There were many factors that led to this war that were short term and long term.
