Of all the videos you've ever posted, this one is by FAR the most recent.

I am an electrician from SF, CA. However, when I was right out of high school I wanted to be an Entomologist!!!! I am still fascinated with insects and animals for that matter with an affinity for pitbulls!!!!! Thanks for the knowledge in all your videos. I wish more ppl wanted to keep their brains sharp. GOD bless x happy holidays

Who needs "aliens" when we already have these bizzarely alien bugs, sea life, fungi, much more.

It's always good to learn something new & it's a safe bet that when a Professor Dave video drops, there'll be plenty for me to learn. Thanks @Professor Dave. You could spend a year expounding on the physiology & behaviours of Insects (Hexapoda), and still not scratch the surface. There are potentially millions of species both alive today & in the extensive fossil record.

Aw man so much serendipity of sorrow of late. I always loved ladybugs and this past week, I found the crushed remains of one beneath my blanket when i awoke, only to ths very next day discover the same, only like a week after seeing one in the kitchen thinking it a sweet unexpected surprise. I collected them as a child, kept as pet (loosely) and designed a character after them and now this although this is positive. I cried, it reminded me of a upsetting incident I had in first grade trying to keep/save 3 caterpillars for my garden, putting them in my cargo short pockets, whilst watching a movie in final hour of school about myth making interacting with animal traits like mosquito whispering in ear or leopard/cheetah fur patternage. I came hom excitedly and opened the pockets to see their dead bodies staring perfectly at me. I threw them away and cried terribly. I have always loved insects, and arachnids of all. I felt wretched during spring cleaning a few years back when I auto reacted to seeing a black widow scurry towards my hand when i was on the ground sweeping my bed cupboard. Such a rare gift to have shared such near by quarters of reprieve and I entirely auto reacted by hitting it. I didn't process it's make until had killed it. I always save insects and especially spiders and try to keep them relocated to woodpile or basement/ garage but I just killed it. I had a empty cup right there. I know just alot from little but the timing of this with the bug bloodshed in bed, besides everything else going on is really depressing synergy though I like this instance the relative lack of distance time wise feels a bad portent. I just feel sad I killed them in the few scraps of sleep I manage from severe insomnia. Especially with such baneful time of year for several reasons. Just sucks. Sorry for obnoxious derailment of your effort. I weren't purposefully tryst to be rude or selfish. Forgive me if abled/wills Thanks regardless for work or clemency if it be your will. Take care.

What I would have said in the video is, Hexapoda-the most diverse subphylum in the entire Arthropoda phylum and a stunning example of evolutionary adaptation and specialization. When we examine Hexapoda, we're looking at a lineage that has not only adapted to nearly every conceivable ecological niche on the planet but has also mastered the art of specialization in form and function. The sheer diversity among insects is nothing short of astounding, with adaptations ranging from intricate flight mechanics to specialized mouthparts, allowing for feeding on an incredible variety of substances. Hexapods, as their name suggests, are defined by their six-legged structure-a body plan that has proven remarkably effective for locomotion and stability on land. This hexapodal structure, combined with their three-part body segmentation (head, thorax, and abdomen), allows for efficient movement, feeding, and sensory processing. The head typically houses highly specialized sensory organs, including compound eyes, antennae for environmental detection, and a range of mouthparts adapted to specific diets. For example, consider the piercing-sucking mouthparts of a mosquito, the sponge-like mouthparts of a housefly, or the strong, grinding mandibles of a beetle-each a masterclass in evolutionary engineering, adapted for particular ecological roles. Hexapods also have an exoskeleton made of chitin, providing both protection and structural support while minimizing water loss, which is crucial for terrestrial survival. This lightweight yet robust exoskeleton, combined with jointed limbs, gives insects an unparalleled range of motion, enabling complex behaviors like burrowing, climbing, and, of course, flight. In fact, insects were the first animals to evolve powered flight, a revolutionary adaptation that not only allowed them to evade predators but also to exploit new habitats and resources with extraordinary efficiency. Moreover, the respiratory system of hexapods is another marvel. Rather than relying on a centralized lung system, they use a network of tracheae-tiny tubes that deliver oxygen directly to cells, bypassing the circulatory system entirely. This adaptation allows for efficient gas exchange, even in tiny, rapidly moving organisms. And, of course, we can’t overlook the hexapod lifecycle itself. Many undergo complete metamorphosis, a four-stage process (egg, larva, pupa, adult) that minimizes competition between young and adult stages by allowing each phase to exploit different ecological niches. In short, the hexapods exemplify the success of modular, specialized structures working in concert-a true masterpiece of natural selection, illustrating how life on Earth continues to refine itself in response to environmental pressures. They are both nature’s engineers and explorers, inhabiting every corner of the globe and adapting to nearly every imaginable habitat, from arid deserts to lush rainforests to the icy reaches of Antarctica. Insects are, quite simply, one of the most profound success stories in the history of life on Earth.

Dave could you make a video debunking Marilyn Vos Savant’s claims on the schooling system making kids dumb? She has the highest recorded iq in history.
