  • Fish consumption advisories for expecting mothers fail to cover all types of contaminants
    Fish consumption advisories for expecting mothers are ineffective in reducing infant exposure to contaminants like persistent organic pollutants. The researchers' model estimates that women who stop eating fish shortly before or during their pregnancy may only lower their child's exposure to POPs by 10 to 15 per cent.
  • How vision makes sure that little fish do not get carried away
    Our eyes not only enable us to recognize objects, they also provide us with a continuous stream of information about our own movements. The world glides by us and leaves a characteristic motion trace on our retinas. Seemingly without effort, our brain calculates self-motion from this "optic flow." This way, we can maintain a stable position and a steady gaze during our own movements. Scientists have now discovered an array of new types of neurons, which help the brain of zebrafish to perceive, and compensate for, self-motion.

  • Ocean acidification robs reef fish of their fear of predators
    Research on the behavior of coral reef fish at naturally-occurring carbon dioxide seeps in Milne Bay in eastern Papua New Guinea has shown that continuous exposure to increased levels of carbon dioxide dramatically alters the way fish respond to predators. 

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 .
