  • Lousy sockeye are lousy competitors
    A key discovery has been made regarding Fraser River sockeye's vulnerability to sea lice. Their recently published research indicates that juvenile Fraser River sockeye salmon that are highly infected with sea lice are 20 percent less successful at consuming food than their lightly infected counterparts.
  • Coal-tar-sealant runoff causes toxicity and DNA damage
    Runoff from pavement with coal-tar-based sealant is toxic to aquatic life, damages DNA, and impairs DNA repair, according to new research. Rainwater runoff collected as long as three months after coal-tar-sealcoat application caused 100% mortality to minnows and water fleas, which are part of the base of the food chain.

  • Tropical marine ecosystems most at threat from human impact
    An international team of scientists has used the fossil record during the past 23 million years to predict which marine animals and ecosystems are at greatest risk of extinction from human impact. The researchers found those animals and ecosystems most threatened are predominantly in the tropics.

Ethan Daniels

ethan_danielsFollowing a recent trip to the Dominican Republic, Photojournalist and Underwater Photographer Ethan Daniels has provided ReefID with some fantastic shots of Humpback Whales (Megaptera novaeangliae) to add to the database.


img_837816835The Humpback Whale is one of the largest species of baleen whales ranging from 12-16 meters and weighs approximately 36,000 kilos.  It is an extremely acrobatic animal that often breaches and slaps its tail making it extremely popular with whale watchers.

 
Found in oceans and seas around the world, the humpback is a traveler.  They typically migrate up to 25,000 kilometers from polar waters where they feed in the summer to tropical or sub-tropical waters to breed and give berth in the winter.

 

Ethan uses his extensive background in marine biology and photography to lead informative and fun trips to see these majestic animals as well as many other fantastic creatures through Wilderness Travel.  He has also produced the books "Under Cape Cod Waters" and "Coral Triangle Seascapes" along with his personal website www.oceanstockimages.com .
