Sea angels, telescope fish and blanket octopuses might be actual monsters
Reclusive telescopefish stay practically a mile under the ocean’s floor, the place they feed on bioluminescent creatures. They orient themselves vertically to select the silhouettes of prey swimming overhead, then strike with their nasty jaws. At any time when they ingest a glowing meal, they threat lighting up from inside, broadcasting their location to their very own predators.

As a substitute they preserve every egg heat on the highest of their toes. 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 toes tall, the kings are the second-largest of all penguins, eclipsed solely by the emperors.
