A team of 102 scientists spent a year surveying a small area of the San Lorenzo rain forest in Panama to count the number of species of arthropods living there. After collecting 129,494 specimens—using nets, traps, shovels, tree-climbing harnesses, helium balloons, and other creative gear—it took the team eight years to sort and identify the arthropods. Which of the following nested groups best describes the taxonomic context for the San Lorenzo project? a. Animalia > Bilateria > Arthropoda > Ecdysozoa b. Protostomia > Lophotrochozoa > Ecdysozoa7 Arthropoda c. Arthropoda > Protostomia > Ecdysozoa > Bilateria d. Bilateria > Protostomia > Ecdysozoa > Arthropoda

Hello everyone and welcome to today's video. So which of the following provides the most accurate taxonomic information about spiders. Remember that spiders are going to be arthropods and within arthropods there are a sub group called arachnids. Now that we know this, let's jump into the answer choices so that we can solve the problem. Beginning by answer choice A. Here in answer choice A something very interesting happened. We have crustaceans. Now here, spiders are not going to be a type of crustaceans, crustaceans are usually craps and other organisms are aquatic spiders are not crustaceans. So we're going to cancel this out and we're going to do the same with answer choice B. Because we also have crustaceans here. Now answer choices C and D. Only differ by whether the organism or spiders are going to be Protestants or debtor stamps. If you remember these systems are going to be either taking another matter or core data. Arthropods are going to be Protestants, which is what we see in answer choice C. So we're going to highlight that as the final answer to our question. I really hope this helped you and I hope to see you on the next one.
