I have a summer tradition. Every year, as close to the first day of summer as possible, I hop onto one of the many whale-watching tours that depart from Boothbay Harbor, Maine, and spend an afternoon on the ocean. On a good day we can end up seeing a dozen or so whales. On a [...]

Citizen Scientists, Funding Needed to Help Hawaiian Monk Seal Research Project

Endangered Hawaiian monk seals (Monachus schauinslandi) have a bad reputation among some local fishermen, who accuse the 200-kilogram mammals of eating the fish that the humans catch for their livelihoods. A new project aims to find out if that notoriety is deserved and the public—in particular, teens—has a chance to participate. The National Marine Fisheries [...]

More than 30 years after 50 critically endangered Hawaiian monk seals (Monachus schauinslandi) died of suspected algal toxic poisoning, the presence of ciguatoxins in living seals has finally been confirmed through a new, noninvasive test. Ciguatoxins are produced by dinoflagellates, which live near coral and seaweed. The dinoflagellates are eaten by small fish, which are [...]

Who Eats Whom under the Arctic Sea Ice [Video]

Nereid

San Francisco — Although polar bears and seals have become the poster children for vanishing sea ice in the Arctic, they have thrived for a long time. The bears eat the seals, but what do the seals eat? Maybe fish, although in many parts of the Arctic fish are few in number. Even then, what [...]

Seals, the early years

stem-pinniped-slide-1-600-px-tiny-June-2014-Tetrapod-Zoology

It’s the moment you’ve all been waiting for… stem-pinnipeds at Tet Zoo. Or, probable stem-pinnipeds anyway. This minimum-effort post is brought to you on the back of work showing that pinnipeds (seals, sea lions and walruses) are monophyletic, not diphyletic, and that the taxa shown here – Potamotherium, Puijila and so on – really are [...]
