As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change!
Why do northern and southern populations of Atlantic cod have different haemoglobin subtypes? A recent study upsets over 50 years of theory.
A close look at starfish larvae reveals the beautiful patterns they create while moving through the water. These tiny vortex machines can create lots of swirls around themselves to trap food, or they can let the water flow by them smoothly when they want to swim fast.
Like frogs, sea snakes can uptake oxygen through both their lungs and their skin. How will these “bimodal breathers” cope with warm ocean temperatures?
Greenland sharks can live to be over 400 years old. What can they tell us about ageing?
Juvenile bowhead whales put off gaining length and undergo severe bone loss to invest in growing their massive heads and baleen plates.
Happy Shark Week! Today we examine a persistent and interesting biogeographical puzzle: why are there so few deep sea sharks?
The Antarctic climate is changing, and the increasing temperature is wreaking havoc on the physiology of endemic species. Will icefish, the Southern Ocean’s most abundant group of fishes, be able to cope with the metabolic consequence of life in warm water?
The coelacanth keeps surprising us! Rediscovered off the South African coast in 1938, these animals were once thought to have died out 66 million years ago. Newly characterized lung and fatty structures may have been a key adaptation for their survival in deep-water environments.
As human influence in Earth’s oceans increases, so does the background noise. How might dolphins cope with changes in environmental noise levels, particularly in areas where it has seen a substantial, recent increase? Do chattier dolphins have to invest more energy into their aural physiological systems?
Damselfish offspring inherit a trait developed by parents raised in warmer temperatures.
Ever wondered how your lobster behaves before it reaches your dinner plate? Caribbean spiny lobsters take advantage of a unique sensory system to survive in the wild. Recently, the spiny lobster has been hit by a deadly virus that is threatening population size. How do healthy spiny lobsters avoid other individuals with the disease?
