A rare moment of hope has emerged in the oceans this year. Slalom, a 44-year-old North Atlantic right whale, has given birth to her 7th known calf. This newborn is the 21st calf of the season, marking a record-breaking milestone for one of the most endangered whale species.

For conservationists, each birth counts. With fewer than 400 North Atlantic right whales remaining, every calf represents a vital step toward recovery. This season’s numbers have sparked cautious optimism across the scientific community.

Who Is Slalom?

Slalom is no ordinary whale. She is the oldest daughter of Wart (#1140). Wart is a legendary matriarch in the North Atlantic right whale population. Over her 44 years, Slalom has survived 7 fishing gear entanglements and injuries that could have ended her life.

Despite these challenges, she continues to reproduce. Her resilience is a rare and inspiring example of survival against the odds. Scientists have closely tracked her life, documenting her growth, recoveries and family lineage.

A Record-Breaking Calving Season

This year’s calving season has produced 21 calves, the highest in 15 years. For comparison, some recent seasons saw fewer than 10 calves. This raise concerns about the declining numbers of the species.

Among the highlights, Slalom’s nieces, Millipede and Bocce, have also become mothers, contributing to a remarkable family legacy. Together, this family line represents 3 generations actively supporting population growth.

BIG NEWS: North Atlantic right whales have now welcomed 21 total calves this season—shattering a 15‑year record! 🎉

How Amazed Are the Scientists?

Researchers describe Slalom’s reproductive success as “astonishing.” They note that few whales survive multiple entanglements and continue reproducing at her age. Scientists see her story as a powerful reminder of resilience and adaptability in the face of human threats.

Is This a First Time Ever?

While individual whales have had multiple calves before, Slalom’s 7th calf at age 44 is unprecedented for her lineage and unusual for the species overall. The number of calves this season is the highest recorded in over a decade. This calf was recorded as the 21st of the 2025–2026 calving season.

A Symbol of Survival

At 44, scarred yet thriving, Slalom represents more than one whale’s life story. She embodies endurance, adaptation and hope for her species. Her seventh calf is not just a statistic. It is a living symbol of the delicate balance between conservation efforts and human impact. Slalom’s story shows that recovery is possible if humanity acts to protect these majestic creatures.
