stingray (fish, Dasyatis pastinaca)
Sed nūllum usquam execrābilius quam radius super caudam ēminēns trȳgōnis, quam nostrī pastinācam appellant, quīncunciālī magnitūdine: arborēs īnfīxus rādīcī necat, arma ut tēlum perforat vī ferrī et venēnī malō.But nothing anywhere is as detestable as the spine projecting above the tail of the sting ray, called by us 'parsnip', of five twelfths of a foot in size: it kills trees when driven to the root, punctures weapons like a sword with the force of iron and the evilness of venom.77 CE – 79 CE, Plinius Maior, Naturalis Historia 9
