Scott Kraus and Moira Brown were in Canada，eating pizza with some coworkers．Suddenly，the restaurant’s owner came into the dining room and asked，“Is there a Scott Kraus?There’s a phone call for you．They were in southern Nova Scotia，about l50 kilometers(93 miles)southeast of Main It was practically the middle of nowhere，Kraus thought 0 could possibly know he was there，and what could be so important？

After taking the call，he returned with terrible news．A dead right whale had been seen near Grand Manan island，on the western side of the Bay of Fundy．This is near the border between Maine and Canada．

Kraus and Brown are biologists with the New England Aquarium in Boston．They study the North Atlantic right whale，one of the world’s rarest species．Some cruise(游弋)along the coastlines of North America others live off Europe．Together，their numbers totaled fewer than 350 in l 992，so losing even one was troubling．

The next mornin9，the scientists set sail to view the whale，hoping they could figure out how it died．As her carcass came into view，they sadly recognized that they knew this whale．It was one they had earlier named Delilah．

It appeared the l3一meter-long animal had been accidentally hit by one of the ships that regularly salt through the Bay of Fundy．The biggest ones can be as tall as l0一story buildings，span more than 300 meters and weigh tens of thousands of tons．These ships cruise much faster than a 37metric-ton right whale can swim．

Later that day，one storekeeper brought out pictures he had taken biologists could make out a small baby whale in the photos．It had been swimming beside Delilah’s body．
