Humpback Whale Calves Born Farther South Than Previously Known
Imagine humpback whales having babies while they're on a long trip.
Scientists thought these babies were born in specific spots, but they've now found baby whales much farther south, in places like Tasmania and New Zealand.
This means the whales' nursery is bigger than they thought!
These babies, still learning to swim, now have to travel longer distances and face more dangers.
The discovery came after a marine guide spotted a newborn calf in a busy port.
Because of this, scientists are now trying to protect these new areas where the whales give birth.
It's like discovering a new playground for these giant, gentle creatures, and now we need to keep it safe.
Researchers discovered humpback whales are giving birth in new areas, challenging prior beliefs.
Calves have been observed as far south as Tasmania and New Zealand during migration.
This expands the known calving range by up to 1,500 kilometers.
Most live calf sightings have occurred since 2016, with a majority in the last two years.
Findings emphasize the need for expanded conservation efforts to protect vulnerable calves.
