Parasite Claims Beloved Monk Seal in Hawaii
26 Jun
Summary
- Toxoplasmosis parasite confirmed as cause of death for Hawaiian monk seal Ka'ale.
- Parasite, reproducing in cats, spreads through contaminated feces and water.
- Sixteen Hawaiian monk seals, including Ka'ale, have died from the disease.
A beloved Hawaiian monk seal, known as Ka'ale, has died from toxoplasmosis, a parasitic disease that is a significant threat to the recovery of endangered monk seals and other native wildlife in Hawaii. Federal wildlife officials confirmed the cause of death through autopsy and histopathology results.
Ka'ale, also identified as RH32, was last seen in early March exhibiting normal behavior and was found deceased in May. The 10-year-old seal had previously survived a hooking injury in 2018, receiving rescue and veterinary care.
Toxoplasmosis is caused by the parasite Toxoplasma gondii, which reproduces in cats and spreads via feces. Infection occurs through ingestion of contaminated food or water, impacting both wildlife and humans. The parasite can cause severe inflammation in vital organs, including the brain, heart, liver, and lungs.
NOAA reports that toxoplasmosis is a primary threat to Hawaiian monk seals, with at least 16 known fatalities, including Ka'ale. The actual number is likely higher, as seals often show few symptoms before the disease is advanced, making intervention difficult.
The parasite also threatens other Hawaiian species like spinner dolphins, nene, and alala. Hawaiian monk seals are endemic to the islands, with an estimated 1,600 remaining in the wild. NOAA urges the public to report seal sightings and injuries to aid conservation efforts.
