Humpback Whale Lunge Feeding Technique
November 4, 2011 by staff
Humpback Whale Lunge Feeding Technique, U.S. Coast Guard was monitoring the waters of Santa Cruz, where a group of whales has established an unusually close to shore and drawing crowds threatening the safety of kayakers and other boaters trying to catch a glimpse of the creatures.
Humpback whales, each measuring about the length of a school bus have reached a mile from the land in search of food.
A woman floating on a surfboard and a pair of kayakers only yards away when two of the whales suddenly emerged from the water during the last week of October 2011. He was captured on tape. “Early Show” co-host Chris Wragge and Rebecca Jarvis discussed the incident on Friday.
The Monterey Bay National Marine Sanctuary, said no one has been affected so far, but at least a sailboat was damaged this week when he collided with a whale.
“The large number of people crowding around the whales is not just a problem for the whales themselves, but also public safety,” said Paul Michel, the superintendent of the sanctuary, the San Francisco Chronicle. An estimated 100 people took to the sea kayaks and paddleboards last weekend to take a look.
He worried that the curious might affect the whales while they eat and leave without enough energy to make their migration to Mexico.
This week, the Coast Guard issued warnings sanctuary for people to stay at least 100 meters of the whales or face fines of at least 2500 and the harassment of whales.
Don Croll, professor of ecology and evolutionary biology at the University of California at Santa Cruz, said that whales are good to avoid people while eating, but getting too could pose security risks. He said that whales are “lunge feeding”, which consists of dropping your jaw and swimming just below the surface capture everything in its path.
Croll said watching a show – from a safe distance – is an emotion.
“Lunge feeding is probably one of the biggest events of biomechanics on the planet. It’s a very, very big for people to see,” he said.
Feeding areas for humpback whales are usually far from the coast, but the researchers cautioned that the weather years have brought closer to the ground anchovies, and whales have been followed.
The whales are likely to continue in Santa Cruz for a few weeks before moving south.
