. Elements of zoölogy. Zoology. 220 BACKBONED Fig. 265.—Green turtle. The eye-openings are placed vertically. They attain a length of eight feet, and a weight of twelve hundred pounds.* The loggerhead \ is nearly as large. Its shell is made up of scales. They breed upon Loggerhead Key, Florida, and other lo- calities, bury- ing their eggs in the sand, leaving the sun to hatch them. The digging and covering is done by the hind-flippers. The green turtle (Fig. 265) is somewhat similar, though more delicate, the head and flippers smaller. They feed upon algae, particularly Zos- tera ?na

The hawkbill % (Fig. 266) is distinguished * The gigantic extinct Protostega gigas was allied to the Sphargis. It measured seventeen feet between the fore-arms or flippers, and was remarkable for the rudimentary character of the bones in the adult. f The loggerhead is extremely powerful, and I have found it diffi- cult to turn one with the help of two men. By seizing them by the shell just over the head I have been carried a long distance in the water at a rapid rate. The steeds thus experimented upon were kept in an inclosure half a mile long and eight feet deep, and when asleep on the bottom could generally be caught by diving. Owing to their sluggish natures they often fall a prey to sharks to the extent of their flippers. I have caught them in the Gulf Stream with these organs entirely bitten off. \ Though the hawkbill is a vegetable feeder as a rule, they some- times attack the Physalia (Fig. 19). One, two feet long, was found by the author floating on the surface, insensible, its head covered by the blue tentacles. By scraping them off with a knife the turtle recovered, and was kept as a pet for a long Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Holder, Charles Frederick, 1851-1915;
