16. The Deep-Sea Dumpling Squid (Euprymna berryi)
The Deep-Sea Dumpling Squid is a charming oddity, recently observed at depths deeper than ever before. Its compact, rounded body and scattered bioluminescent spots give it an almost whimsical appearance, setting it apart from its relatives. These glowing patterns not only help it hide from predators but also make it a standout among deep-sea cephalopods. Find additional information about this peculiar squid at Science News.
