What is the size of an orange and looks like a squishy finger puppet with a smile on its face?

Helicocranchia pfefferi, the Piglet Squid! Thanks to a unique pattern of its pigment cells, this little deep sea creature looks like a cuddly character from a children's book. The squid's body is mostly transparent, except for patches of pigment-bearing cells in its skin giving it its happy-face pattern. Although not much is known about the creatures, researchers take their body shape as a hint. Rather than darting about as many squid do, the Piglet Squid are more likely to bumble along in the currents below 100m (320 ft) and catch whatever small prey happens to swim by. According to the UK-based Telegraph, this specimen, about the size of an orange, was collected by the Cabrillo Marine Aquarium where director Mike Schaat managed to capture it on film.
