Remembering Owls Head

Historically harbor seal pup season has always been the busiest, most demanding season for the NMLC animal care team both physically and emotionally. It requires our team to be here round the clock, to serve as surrogates as these abandoned pups must now learn all of their critical survival skills from us without becoming habituated, and due to the fragility of these animals, the team has to be ready for anything- including death.

Marine Mammal Parasite of the Month- March 2021 Answer

Posted by on Apr 1, 2021 in Featured, Under the Microscope | 0 comments

The parasite is known as the Bolbosoma species, a member of the Acanthocephala phylum. Due to its appearance, its common name is “thorny-headed worm”. A Bolbosoma infection can be diagnosed through visible larvae in the fecal matter. An animal with abdominal discomfort can also be in indicator of intestinal worms. Unfortunately, no effective treatment has been found for this infection in marine animals. Most of the information on this mature parasite comes from worms examined after being removed from the dead animals’ intestine. In human...

Marine Mammal Parasite of the Month- March 2021

Posted by on Mar 18, 2021 in Featured, Under the Microscope | 0 comments

This parasite is most commonly reported in cetaceans, but some cases has been seen in pinnipeds, fish and rarely humans. It is distinguishable thanks to their longitudinal rows of overlapping hooks on their proboscis, the hollow retractable extremity used to latch onto its host. This parasite can be as small as 1millimeter long or grow to over 1 meter long! It inhabits the small intestine of its host and cannot complete its life cycle without a vector or intermediate host. Experts can name 14 nominal species of this parasite, each with a...

Since our most recent blog post in November, a lot has been going on here at NMLC! We’ve been kept busy by a record-breaking sea turtle stranding season here on Cape Cod. Here’s a quick rundown of some details from this sea turtle season:  A total of 1174 sea turtles were reported by the Mass Audubon Wellfleet Bay Wildlife Sanctuary this season. Not all of these turtles were still alive when they were found, but this season did see the highest number of live strandings ever recorded in Cape Cod! Sea turtles that were still alive when...

Parasite of the Month- Answer December 2020

Posted by on Dec 17, 2020 in Featured, Under the Microscope | 0 comments

This parasite is Zalophotrema hepaticum, a species of trematode or fluke. Pinnipeds obtain this parasite through the ingestion of infected fish. Although this species is usually confined to the liver, recent studies have found evidence of this trematode migrating to the brain of sea lions, laying eggs, and causing fatal brain damage.     Posted by Meaghan K.

This is a parasite we often find in pinnipeds. Although the most common host is the California sea lion, they are also found in Stellar’s sea lions, northern elephant seals, and Pacific harbor seals. This parasite is usually found in the liver or the adjacent bile duct. It can reach up to 21mm in length and 5mm in width. This parasite also has an oral sucker use for attaching to the host’s organs. What is this parasite and how does it affect pinnipeds?     Posted by Meaghan K.

Heartworm in Phocids

Posted by on Nov 27, 2020 in Featured, Teaching | 0 comments

Phocids, also known as earless seals or true seals, are common coastal marine mammals. Since 1972, seals have been protected under the Marine Mammal Protection Act and are cared for frequently in rehabilitation settings. Beyond human interference, seals encounter a variety of diseases and infections while in the wild. Parasitic infections are regularly found in wild seals and, in some cases, can have detrimental effects on the seal’s health. When trying to maintain healthy population sizes, it is important for animal care professionals to...

A lot has happened here at NMLC since our last update in October. Montauk, a harbor seal who was recently released after restranding due to human interaction, has returned to our hospital for a third time. After being released on Scusset Beach on October 15, 2020 with Marblehead and Derby, two other rehabilitated harbor seals, Montauk was seen for several days around Scorton Creek in Sandwich, MA.

These ova belong to the genus Diphyllobothridea or the tapeworm. Tapeworms have a specialized scolex with suckers used to attach to the intestines of their host and are transferred to pinnipeds who eat infected fish. Using the fecal ova to identify parasites is important to seal rehabilitation at NMLC.     Posted by Meaghan K.
