Where other bugs fear to tread: seals carry superdiving lice

Seals carry their lice everywhere they go, including their deep dives in the ocean. But how do seal lice fare under the crushing water pressure? Miraculously, they live, which makes them the only insects known to survive under the sea. Anastasia YandulskayaI am a PhD candidate at Northeastern University in Boston. I study regeneration of […]

Threats to Cetaceans: There’s More than Meets the Eye

Researchers spent seven years specifically studying deceased, stranded cetaceans along the coastline of the Canary Islands in Spain to figure out what most likely caused their deaths. They found that while human activity accounted for a large portion, something else was responsible for a much larger percentage of cetacean death. Rishya NarayananRishya is a multimedia […]

Grunts and Gnathiids: One Fish’s Daily Migration to Escape Parasites?

Animals move for a number of reasons. The French grunt leaves the coral reefs at night for seagrass. A group of scientists proposes and provides good evidence for why they might do that! Read on to discover whether they’re leaving to avoid being parasitized? Rebecca FlynnI am a graduate of the University of Notre Dame […]

Can being sick be a good thing for surviving ocean acidification?

Scientists (myself included!) have been doing a lot of work on how marine animals respond to rising carbon dioxide (CO2) levels, but CO2 alone isn’t the only problem. This study looks at how having a parasite affects survival in marine snails exposed to high CO2 – do they survive longer in those conditions with or […]

Passive Sampling for Antiparasitics near a Chile Salmon Farm

An increase in the number of positive cages and cage-level abundance of sea lice in southern Chile was shown since 2004. The prevalence of sea lice in the fish farms was 53.4%, and the average sea lice abundance was 11.8 per fish (poor salmon)! In order to gain control over parasites, synthetic pyrethoid has been […]
