Key terms mentioned in this video: Annelids Segmentation Arthropods Coelem Cephalothorax Crustacea Insect (Population compared to other organisms) Summary of this video: While humans and chordates may be pretty complex species, we could not have been so mighty without insects. On a side note, insects topple all other organisms combined. That being said, we must learn about these insects to get a better understanding of ourselves. Across the Disciplines: Angiosperms ("flowering plants") required the use of insects to evolve.

I feel I need to personally thank you Hank for these videos. I know they are mostly for biology students and such, but I make my kids watch them. They are 7, 6, 4, and 2, and the LOVE them. A few days after watching this video my husband and I went out and left the kids with a sitter. Imagine her surprise when my 2 year old made a worm out of blocks, pointed to it and told her "Look it's segmented!" Your crash course videos are making my homeschooling even more effective! Thank you!

I find it funny how in my culture people despise insects and say that people who eat them are dirty and gross. Yet everyone here likes to eat shrimps, crabs and lobsters…
@MysteriousAsteria
@MysteriousAsteria 8 лет назад
Everything should be okay, as long as the animal eaten is treated well before consumption and as long as if it's edible (obviously). An animal's cuteness or beauty should not be a reason not to consume it. Though I can see why eating a butterfly could be nonsensical. But in some regions people eat grasshoppers though. And where I live we eat lots of cute cows, goats, pigs and birds. I find it silly when people say they don't like it when beautiful animals are eaten, as if it were only okay when an animal is "ugly". Also I doubt a butterfly is beautiful for a reason. After all beauty is a human concept and not an inherent quality created by nature.

@moth9442 9 лет назад
pretty spot on, but, in partial metamorphosis often a key difference between adults and nymphs is that the nymphs always lacks wings, while the adults may have them (although in some cases the wings are not suited for flight.) Examples include mantids, stick and leaf insects, and cicadas, to name a few. So, the difference between partially metamorphosing nymphs and adults is not just limited to size.
