Thousands of seal fetuses found dead

Several thousand dead seal fetuses have been washed ashore at Pelican Point in Namibia, several international media outlets report, including The Independent.

The bodies were discovered by the organization Ocean Conservation Namibia, which sent a drone out to the seal colony on October 5, and could count several hundred of them lying in the sand.

– All the red circles show dead baby braces. A rough estimate is more than 5,000 in this colony alone. This is tragic, as it accounts for a large proportion of the newborn baby seals that were expected at the end of November, the organization writes on Twitter.

The dead fetuses must be African fur seals. The species lives primarily along the coasts of Namibia and South Africa.

Researcher worried

Tess Gridley at Stellenbosch University is part of the research team that monitors the situation for seals in the area. She tells The Guardian that it is normal to find dead baby braces at this time of year, but not on this scale.

She is said to have discovered several dead fetuses already in August. Around 150 have also been found at the Cape Cross colony further north. She says that the estimate of 5,000 is uncertain, as many carcasses are probably eaten by scavengers.

– This may mean that the ordinary gestation cycle is disturbed for the affected colonies. Usually the females will give birth to one offspring each year, before they quickly become fertile and mate again. If the females miscarry, they can become fertile earlier, while the males have not prepared for the mating, she says, and adds:

– The females are also very thin, and may be unable to reproduce, she says.

Gridley cites food shortages, diseases and toxins as possible causes, but points out that they do not currently have data confirming this.

Researchers are now working to collect data to analyze the cause of miscarriages.
