• The Albatross is the largest sea bird of the world. Some species have bodies that are up to 1 m long, weigh up to 9 kg and have a wing span width of up to 3.4 m. Ashore they look rather clumsy, waddling along. Although most of the time they sit on their nests, as breeding and rearing youngs is their only on land activity.

    But don't let the albatrosses on-land performance fool you. As soon as they take off from a cliff into a stiff wind they become the most elegant gliders. Out over the ocean with their long

  • Atlantic Cod (Gadus morhua) used to be one of the most eaten fish in temperate regions of the western hemisphere. It was ubiquitous from the Baltic Sea, via North Sea throughout the whole north Atlantic. Adults live mainly in deeper, colder water, while juveniles are more likely to be close to shore, in 10-30 m depths. Cods migrate between breeding, feeding and overwintering grounds, but the migration paths are usually not very long ones – usually less than 200 km. Thus, local factors can highly influence a population. Cod feeds on invertebrates and small fish like herring. In their

  • The marine food web is based on microalgae, which are eaten by small algae-eaters (algaevores), mostly small, drifting animals (zooplankton). Free-swimming algae (phytoplankton) and zooplankton are food for plankton-eaters (planktivores) of different sizes. The smaller planktivores, like reef fish, are preyed upon by bigger carnivores, which are eaten by even bigger carnivores.

    The monk seals are one of Hawaii's iconic species. But for how much longer? They are at the brink of extinction. Numbers are decreasing every years, due to too many pups and youngsters dying. But there is hope, as the numbers are actually increasing in part of the archipelago. How can the rudder be turned for the total population to grow again? A short overview.

    Correction: The Monk Seals DO NOT eat half their body weight per night! That is a tremendous exageration.

  • In the context of the International Building Exhibition IBA 2013 in Hamburg, Germany, the first algae bioreactor house was build. Algae-filled solar panels are the center of the house's energy cycle. One one hand, they produce heat by absorbing solar energy, which is used to heat the house and produce warm water.On the other hand they produce biomass for biogas production, which is used to provide electrical energy and more heat.How the energy cycle and thus the house works, we explain in this short video.

  • Boxfish are often compared to helicopters. Their box-like shape reminds of some helicopters, the "rotation" of the pectoral fins remind of helicopters. And like helicopters, the heavily armored boxfish can hover, move slowly, at medium speed, or fast. How they do that, you can see in this OceanQuicky.


  • Sea cows are aquatic mammals feeding on plants, while all other fully aquatic mammals are predators or filter feeders. As order the sea cows, Sirenia, are more than 60 million years old. While some species are only known from fossil findings, five species were known to humans. The largest one with up to seven meters body length, Steller’s sea cow, was extinct less than 3 decades after being discovered in the 19th century. Today, four species remain: one dugong and four manatees.


  • At almost every coast, which is inhabited by humans, mackerels are fished. Sometimes overfished. Mackerles, Makrelen, or Macarelas are distributed from the cold northern Atlantic to the tropics, from the surface to 1000 m depth, from open water to coral reefs. But it is not just one species of fish. At least 23 different species hide behind this name in different parts of the world, and in different languages. Here a small overview over the diversity of mackerels.

    There are a number of animals in the sea, named after musical instruments. Or are the names a coincidence? I don't think so! The first fish described on Amocean, which falls in this category, has to names reminding of instruments: Flutemouth or Bluespotted Cornetfish:

  • In the last few years I often heard or read about drugs derived from marine organisms as argument for ocean conservation: We should not destroy our own cure, so let’s careabout oceans and prevent the destruction of coral reefs! 

    I don’t like such anthropocentric reasoning, which only allows organisms to live when they directly serve the human species. But
