STONY BROOK, N.Y., Dec. 6 (UPI) -- Female sharks return to their birthplace to give birth, like salmon and sea turtles, U.S. researches report at the end of an almost 20-year study.
Begun in 1995, the study involved the capture, tagging, release and tracking of more than 2,000 baby lemon sharks. The ongoing project yielded the first confirmation of the "homing" behavior in sharks, the researchers reported.
