Harbor porpoise calves ingest toxic chemicals through their mother’s milk

Persistent organic pollutants (POPs), though banned, remain a threat to marine ecosystems, particularly damaged the harbor porpoises in the North Sea. A study found that these porpoises consume high concentrations of such pollutants while feeding, compromising their health and reproduction. Transferred from mothers to calves through lactation, these chemicals, such as PCBs, pose a major concern for the future population of these marine mammals. This calls for enhanced conservation strategies and more responsible individual actions.

Preying on marine mammals might be threatening the survival of Icelandic orcas

Scientists have for a long time thought that orcas in Iceland specialized in eating fish (like herring). Recently, however, experts have noticed that some Icelandic orcas seem to enjoy another type of snack: marine mammals. This could be a problem, and eating marine mammals could threaten the long-term survival of these orcas. In this post, …

Orca Awareness Month: Southern Residents (Part Two)

Make sure to read Part 1 before you read this post. Regrettably, Part 2 is a bit of a downer but is necessary to address. The SRKWs population has been drastically decreasing. The most recent population estimate indicates a total of 73 individuals remaining. Scientists have identified three main threats to the SRKW population: starvation, …
