Why was "tantrum" trending last week?
any of four species of small, tropical marine fishes of the family Centriscidae (order Gasterosteiformes), found in the Indo-Pacific. The name razor fish derives from the shrimpfishes' characteristic sharp-edged belly. Shrimpfishes are nearly transparent, long-snouted, shrimplike fishes, flattened from side to side and covered with a cuirass of fused, transparent armour plates. The armour ends in a long spine (one of the dorsal fin spines), beneath which are the tail and the rest of the dorsal fins.
