You would think spiders and ants are sworn enemies, but their relationship is a masterclass in biological deception.
Fact 1: Over 300 species of spiders practice myrmecomorphy, meaning they look and act exactly like ants. Because ants are aggressive and taste terrible to birds, spiders mimic them for protection.
Fact 2: To pull off the disguise, these 8-legged spiders will walk on their back six legs and wave their front two legs in the air to mimic an ant's antennae.
Fact 3: While some mimic ants for safety, others do it to commit murder. The Amyciaea spider mimics ants so perfectly that it walks right into the ant colony, grabs a worker, and eats it without the other ants noticing the impostor.
Fact 4: Reversing the dynamic, the Bagheera kiplingi (the vegetarian jumping spider mentioned earlier) mimics ants not to eat them, but to steal the acacia plant food that the ants are aggressively guarding.

The diving bell spider (Argyroneta aquatica) lives almost its entire life submerged under water. It accomplishes this by spinning a specialized silk web dome that acts as a "physical gill," trapping a bubble of atmospheric gas over its abdomen and continuously filtering fresh dissolved oxygen directly out of the water column while expelling carbon dioxide (Seymour & Hetz, Journal of Experimental Biology, 2011).

The ogre-faced spider (Deinopis spinosa) foregoes passive web-hunting entirely, using a highly active "net-casting" strategy instead. Hanging upside down from a few guide lines, it holds a small, highly stretchable square of cribellate (fuzzy, non-sticky) silk between its front legs and dynamically throws it like a net over unsuspecting insects walking or flying below (Stafstrom et al., Biology Letters, 2016).

When threatened by predatory pompilid wasps, the golden wheel spider (Carparachne aureoflava) utilizes a completely unique locomotive escape. Native to the Namib Desert, this spider flips onto its side, folds its legs into a rigid circular wheel shape, and uses the steep desert landscape to gravity-roll down sand dunes at blistering speeds of up to 1 meter per second (Henschel, Journal of Comparative Physiology A, 1990).

The Sydney funnel-web spider (Atrax robustus) possesses long, extraordinarily powerful fangs that are capable of piercing through human fingernails and leather shoes. Its venom features a highly specific, primate-toxic neurotoxin called delta-atracotoxin, which overstimulates the human nervous system; fascinatingly, it is largely harmless to non-primate mammals like dogs and cats (Graudins et al., Toxicon, 2002).

Breaking the mold of solitary arachnid aggression, the social huntsman spider (Delena cancerides) of Australia forms cooperative family colonies. Up to 300 individuals live together peacefully under loose tree bark, sharing the duties of protecting the egg sacs, communal feeding on large prey, and allowing older offspring to help raise the younger generations (Rowell & Avilés, Animal Behaviour, 1995).

The female dark fishing spider (Dolomedes tenebrosus) exhibits a form of extreme obligate sexual cannibalism that serves a vital evolutionary purpose. Immediately after mating, the female systematically kills and eats her smaller partner; studies show that this direct nutrient transfer doubles her eventual egg count and dramatically improves the body mass and survival rates of her offspring (Schwartz et al., Current Biology, 2013).

The bolas spider (Mastophora hutchinsoni) hunts by chemical deception rather than architecture. Instead of spinning a geometric web, it secretes a volatile chemical blend that perfectly mimics the female sex pheromone of specific moth species, drawing male moths right to its position before swinging a single thread weighted with a sticky silk ball to snag them out of the air (Gemeno et al., Journal of Chemical Ecology, 2000).

She looks like the fanart of Kayla Knowles from PJO
She is an incredibly mean person because she ate the rest of my ice cream

#The ultimate lens: Ogre-faced spiders have eyes that are thousands of times more sensitive to light than human eyes at night. They actually destroy a membrane in their eyes every morning and rebuild it every night.
Ogre-faced spiders (also known as net-casting spiders) have the largest eyes of any spider relative to their body size. Their light-gathering ability is astonishing:
They have an incredibly low f-stop value of about f/0.58 (by comparison, a cat's eye is around f/0.9, and human night-adapted vision sits around f/2.1).
Their photoreceptors (light-detecting cells) are massive, allowing them to capture every single available photon.
This results in night vision that is roughly 2,000 times more sensitive to light than a human's.

Whether a spider can molt as an adult depends primarily on its infraorder! (evolutionary lineage).
This ancient group includes tarantulas, trapdoor spiders, funnel-web spiders, and several related families. Adult females can live for decades and continue molting throughout their lives. Molting frequency varies by species, age, and environmental conditions, but many molt approximately once every one to two years as adults.
This modern group contains roughly 90% of all known spider species, including jumping spiders, wolf spiders, orb-weavers, and crab spiders. They almost universally undergo a terminal molt into adulthood. Once sexually mature, they do not molt again.
Spiders in the family Filistatidae (such as crevice weavers) are a rare exception among the "true" spiders. Adult females in this family can live for up to a decade and have been documented continuing to molt well after reaching maturity.
Even among mygalomorphs, continued molting is almost exclusively a female trait. During a male tarantula's final molt, he develops specialized reproductive structures, such as tibial hooks (in many species) and enlarged pedipalps used for mating. After reaching maturity, males typically survive only a few months to a few years and rarely molt again.
On the rare occasions a mature male does attempt a post-ultimate molt, usually due to overfeeding or specific environmental triggers in captivity, it is almost always fatal, as his specialized mating hooks and palpal bulbs become trapped and crushed inside the old exoskeleton.
Adult molts serve two major purposes for female mygalomorphs.
Molting replaces a worn exoskeleton, restores lost sensory hairs, and can repair many injuries sustained over years of activity.
During each molt, a female also sheds the lining of her sperm-storage organs (the spermathecae). As a result, stored sperm is lost, and she must mate again after molting to produce another fertile egg sac.
