Linda Whitehurst, 52, was paddling her sea kayak near the eastern resort town of Byron Bay, about 375 miles north of Sydney, when the shark lunge d at her, knocking her into the water, the paddler and police said.

琳达。怀特赫斯特，52岁当时正在东部胜地拜伦海湾划船，拜伦海湾在悉尼北部375英里处，涉水者和警察说，当时白鲨在换气，把她从船上撞到了水里。

There also I have found, in considerable quantities,curious balls, composed apparently of fine grass or roots, of pipewort perhaps, from half an inch to four inches in diameter, and perfectly spherical.
