When sea angels hunt, they rework into monsters. The free-swimming slugs, lower than an inch lengthy, retailer six jellylike “arms” generally known as buccal cones inside their heads (left). After they sense prey—for instance, a close-by sea butterfly—muscle tissues of their core contract, inflicting the arms to shoot out (proper) and seize the goal, in milliseconds. They will additionally tear a sufferer’s physique out of its shell for simpler consumption. Credit score: Alexander Semenov
Sea angels, telescope fish and blanket octopuses may be actual monsters
BLACKOUT EATER
Reclusive telescopefish stay almost a mile beneath the ocean’s floor, the place they feed on bioluminescent creatures. They orient themselves vertically to pick the silhouettes of prey swimming overhead, then strike with their nasty jaws. Every time they ingest a glowing meal, they danger lighting up from inside, broadcasting their location to their very own predators.

DIVE KINGS
King penguins nest in large colonies—typically with a whole lot of hundreds of birds—on sub-Antarctic islands. They don’t construct nests. As a substitute they hold every egg heat on the highest of their ft. The males take the primary incubation shift, which might final for weeks, whereas the females enterprise to the ocean for a well-earned meal. Measuring about three ft tall, the kings are the second-largest of all penguins, eclipsed solely by the emperors.
