Here are three vintage clip art illustrations of sea creatures.
The first illustration features the Heart-Cockle (Cardium cardissa). A Spiral Heart-Cockle (Isocardia cor.) and a Tuberculated Cockle (Cardium tuberculatum) are included in the image. The second illustration features illustrations of a Broad-Claw Porcelain Crab (Porcellana platycheles) and a Common Plated Lobster (Galathea strigosa). The third illustration features a striped fish swimming in the ocean. The scientific name of this fish is Semilunar Holocanthus (Holocanthus semicirculatus) I scanned the illustrations from Wood’s Illustrated Natural History – Reptiles by Rev. J. G. Wood.
I scanned several additional illustrations from the book to create a printable set of vintage sea creatures for my Etsy shop. Both the printable pages and the individual files are included. Please see additional previews in my Etsy shop for the full set of illustrations as they are not all included in this preview. Image is linked to my shop.
