  • Ready for mating at the right time: How pheromones signal mating cues in tilapia
    Fish rely on pheromones to trigger social responses and to coordinate reproductive behavior in males and females. Scientists have now identified such a signal molecule in the urine of male Mozambique tilapia: this pheromone boosts hormone production and accelerates oocyte maturation in reproductive females.
  • How the zebrafish gets its stripes: Uncovering how beautiful color patterns can develop in animals
    The zebrafish, a small fresh water fish, owes its name to a striking pattern of blue stripes alternating with golden stripes. Three major pigment cell types, black cells, reflective silvery cells, and yellow cells emerge during growth in the skin of the tiny juvenile fish and arrange as a multi-layered mosaic to compose the characteristic color pattern. While it was known that all three cell types have to interact to form proper stripes, the embryonic origin of the pigment cells that develop the stripes of the adult fish has remained a mystery up to now. Scientists have now discovered how these cells arise and behave to form the 'zebra' pattern.

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 .
