very year from late April to August, humpback whales migrate north along Australia’s Pacific coast to the warm coastal waters of Queensland and the Coral Sea to mate and give birth. According to Geoffrey Ross, wildlife management officer and coordinator of the Marine Fauna Program for the NSW National Parks and Wildlife Service (NPWS) off Cape Solander south of Botany Bay, humpback whale migration periods are becoming longer annually as their numbers increase.

This Community Education program is for both the Medical Community and the Diving Community. Bringing together nationally and internationally known speakers on topics of dive safety, medicine and training.

"By changing colour to imitate local damselfish communities, dottybacks are able to overcome the predator avoidance behaviour in the juvenile fish they hunt," said Dr William Feeney, co-author of the study from the University of Cambridge's Department of Zoology.

"The dottyback behaviour is comparable to the 'wolf in sheep's clothing' scenario from Aesop's Fables, where distinguishing the predator from the harmless 'flock' becomes increasingly difficult when they look alike - allowing the dottyback to creep up on unsuspecting juvenile damselfish," Feeney said.

Operators claim new federal regulations meant to protect marine mammals could put them out of business. Wally Daudrich, president of the Beluga Whale Tourism Association and owner of the Lazy Bear Lodge in Churchill, Manitoba, claims rules prohibit boats from approaching belugas any closer than 50 metres.
