- Field guideHow squid use jet propulsionA squid is a pulsed water pump with fins. It draws water around the head into the mantle cavity, closes that route, squeezes the mantle, and ejects a directed jet through the funnel to accelerate in the opposite direction.
- Field guideHow bioluminescence worksDifferent lineages make, obtain, or host different light-producing chemistries, package them in cells or photophores, and control flashes or glows for camouflage, prey capture, defense, communication, or mating.
- Field guideHow seabirds handle saltKidneys alone cannot efficiently excrete all the salt gained from seawater and marine prey while conserving water. Nasal salt glands actively move ions into a secretion saltier than blood; ducts carry it to the nostrils, where droplets run or are shaken from the bill.
