Can be specialists or generalists: specialists: adaptations for eating specific food. Stylet: use to puncture the vascular tissue. Detection of food via sensory adaptations (cid:494)sight(cid:495) (cid:494)olfactory(cid:495) (cid:494)taste(cid:495) (cid:494)hearing(cid:495) (cid:494)touch(cid:495) Physically overpower prey: predators and prey are equal sizes. Venom: prey often larger than predators. Hypostome: facilitates nutrient acquisition digestive lining over entire body on (cid:494)teeth(cid:495) You can be amazing at finding and capturing food but if you can(cid:495)t keep a hold of it long enough to eat it why waste the energy: handling food, eat really fast, protect your food, store it.
