The story of the word

ἰχθύς gave the early church its fish sign, because the five letters work as an acrostic for Ἰησοῦς Χριστὸς Θεοῦ Υἱὸς Σωτήρ, Jesus Christ, Son of God, Saviour. The scientific word arrives in the 1640s, when European naturalists were still arguing about what counted as a fish and whales and shellfish were both on the list. Fossil hunters later used the same root for Ichthyosaurus, the fish-lizard.
