Eavesdropping prawns get more than they bargained for
Marine animals living below the surface have to put up with noise generated by human activity. Heavy shipping traffic can bring a lot of noise. How does the common prawn respond?
Honey, we shrunk the seafood
Atlantic surfclams have gotten smaller over the last thirty years. This modeling study explores how temperature and how we fish can change the average size of individuals in a population.
What makes a male squid put in reproductive effort?
Male squid can vary the effort they put into each mating event. Find out what type of female makes the males put in the most energy.
Variety in the personal lives of triggerfish
Triggerfish don’t all opt for monogamy. Read on to see what mating strategies they use and why there is so much variety.
Sea turtles vs Airguns
As we look for oil beneath the sea floor we cause a ruckus. How do sea turtles react and how can we protect them from the disturbance?
A new king (crab) of the Antarctic
Temperatures are increasing at the poles (and worldwide) and shifting the balance of predator-prey interactions. Predatory king crabs are moving into the Antarctic. How will it change the ecosystem?
As the Caribbean sand heats up female sea turtles rule the beach
The sex of sea turtle eggs depends on the temperature of incubation. What happens when the sand heats up?
How important are claws to stone crabs?
The stone crab fishery does not remove the whole crab, only the claws. How do the clawless crabs fare when returned to the wild?
Tiny lobsters, big problems.
Larval lobsters face potentially dangerous situations, find out how they fare against a couple important environmental stressors (salinity and pH changes).
Sex and parasitism on the open sea and in a fish’s mouth.
Parisites live in fish mouths and undergo opportunistic sex changes.
Marine invertebrates- no backbone just makes them easier to eat.
Invertebrate fisheries are on the rise, invertebrate fishery management needs to rise along with it. This study examines the the impact of fishing invertebrate species on population numbers of animals in the ecosystem.
Seeing in the dark: zooplankton in Arctic winter.
Winter nights are very long and dark near the poles. How well can krill and other zooplankton see to get around?
Sea urchins and their pathogens: a relationship that’s heating up.
The relationship between sea urchin, their amoeba pathogens and their kelp prey is changing with the climate. Find out how!
One fish, two fish, small fish- don’t fish!
Fishery management is complicated, but important. Read more about one way to protect young fish from the Icelandic longline fishery.
Busy penguins strive to find an energy balance.
Penguins find a way to balance the extra work of the breeding season while still finding time to go diving to find food.
Are bigger moms better moms?
We know that larger female fish produce more eggs, but does this really mean they produce more young that grow into the next generation?
Two Crabs and an Alga- a story of protection and evolution.
Tiny mud crabs try to escape big blue crab predators but without the help of evolution to guide shelter choices what will they do?
Sea-ing fewer stars: Virus linked to sea star mass die offs.
Sea stars have been dying by the millions on the Pacific coast of the U.S. and now we have an explanation.
New housing options in unlikely places: Animals and oil platforms.
Real estate in the open ocean is a hot commodity. This research shows how enthusiastically fish and invertebrates take advantage of new habitat.
Parasitic crabs steal food and the possibility of offspring from unsuspecting snails.
Crabs find a home inside sea snails leading to reproductive disaster.
