Spiders are among the world’s largest and most diverse animal lineages. They have diverse behaviors. For example, some families build webs for prey capture whereas others are active hunters that stalk their prey using vision. These behaviors correlate with differences in their visual systems. The number, complexity and arrangement of spider eyes vary across spider families. Spiders thus provide an opportunity to undertake comparative studies. In particular, very little is known about the neurobiology of spider brains. Spider brains are very different than those of insects and even other chelicerates, such as scorpions and harvestmen. Due to the absence of a dedicated olfactory/chemosensory appendange, spiders lack the associated neural processing regions found in most other arthropods. Spiders are also the only known chelicerates that lack immunoreactivity to proteins involved in arthropod learning and memory found in other arthropods. Instead, most of a spider’s protocerebrum, the first segment of its fused nervous system, is dedicated to visual processing. The size and organization of the visual processing regions of the protocerebrum varies across spider families.
Comments
Awkward Sentence
I think you did an awesome job with this paragraph and I love the topic you chose! My only comment is on your second sentence, "They have diverse behaviors". It is so brief that I feel like you could combine it with another sentence or expand more on the thought.
I also think this was a good
I also think this was a good paragraph. I agree that you could combine the second sentence with another because it is short. You could also add an oxford comma to the list "number, complexity, and arangement"
continuing thought
Adding onto rmmcondald's comment on your second sentence, I think that sentence could have been added to the end of the first sentence, and then further explain your thought in a second sentence. Also, after you mention that spider brains are different when compared to other insects, continue your thought! In what ways do they differ? How are they similar? "An absence of a dedicated olfactory/chemosensory appendage" when compared to who?
define
I appreciate the use of scientific terminology here, it really improves the paragraph as a whole. However I think you should include definitions for some of the more challenging or study-specific words such as chelicerates. Imagine someone outside the course of study reading this and trying to understand what it's about. You want your paragraph to be informative but also easy to understand, hopefully so the reader doesn't have to look up the information you are conveying to them. Overall very interesting (I love arachnids)
