Now we got bad blood: Oxygen binding is not affected by haemoglobin subtype in Atlantic cod

Why do northern and southern populations of Atlantic cod have different haemoglobin subtypes? A recent study upsets over 50 years of theory.

What killer whales tell us about menopause

Killer whales, or orcas (Orcinus orca), are amazingly intelligent and social animals. What can they tell us about the evolution of menopause?

Warm water curtails sea snakes’ dives

Like frogs, sea snakes can uptake oxygen through both their lungs and their skin. How will these “bimodal breathers” cope with warm ocean temperatures?

Swashbuckling spiders sailed the high seas

Long before the Vikings reached North America, a group of coastal spiders was already sailing around the world using prevailing winds, currents, and rafts.

Long-lived sharks challenge ageing theory

Greenland sharks can live to be over 400 years old. What can they tell us about ageing?

Do algal blooms kill whales?

Since 2005, southern right whale calves have been found dead in historic numbers off the Patagonian coast in Argentina. Scientists investigate whether harmful algal blooms may be to blame.

Pet trout: domestication rapidly alters gene expression

The impact of domestication can be detected within one generation in steelhead trout, and may involve adaptation to highly crowded conditions.

Young whales build baleen out of ribs

Juvenile bowhead whales put off gaining length and undergo severe bone loss to invest in growing their massive heads and baleen plates.

A lot of interesting work has been doing on sea turtle nests, some of which has been covered on Oceanbites. Did you know warm nests produce more females?  Or that rising sea levels hinder hatching success?  [Flickr - Jeroen Looye]

With a little help from my friends: sea turtles hatch together to save energy

Sea turtle hatchlings face long odds when they emerge from their buried nests. But at least they don’t have to dig themselves out alone.

Happy Shark Week! Today we examine a persistent and interesting biogeographical puzzle: why are there so few deep sea sharks?

Why don’t sharks go deep?

You look like your mom: parental effects in Atlantic salmon

In honour of our Mother’s Day theme week, we’ll look at how the environment experienced by parents during reproduction and their early life history influences their offspring.

Turtles turn heat exchange topsy-turvy

Counter-current heat exchange is a classic example of an elegant anatomical solution to this physiological problem. Leatherback sea turtles do things just a little bit different.

Oxygen favours the bold

It takes personality for the African sharptooth catfishes to breathe air. But they also consider their surroundings before visiting the surface. Photo: Wikimedia.

Trawling selects for faster fish

A new study suggests that differences in exercise performance make some individuals more vulnerable to capture by trawling than others, and that this may drive the evolution of commercially-important fishes (Photo: Wikimedia).

Icefish can’t keep their cool in warm water

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 and its leftover lung

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.

Sound waves: dolphins in a noisy ocean

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?
