Great news from South Georgia, where an Antarctic blue #whale photographed in 2019 has been re-sighted in 2026! Whale “Magrathea” comes from a small but growing photo-ID catalogue (42 individuals) of this Critically Endangered whale at #SouthGeorgia, collected by visitors & researchers
Side-on photograph of an Antarctic blue whale in the water. There is a white mark around the dorsal fin. Photograph taken by Taryn Lawson, HX Expeditions. Image of the dorsal fin and flank of an Antarctic blue whale swimming away from the camera. A white mark is visible around the dorsal fin and lower on the back.

Learn how to draw a North Atlantic Right Whale at the Science Museum of Virginia. Sad thing is that enough kids draw these each day to represent the entire population (c. 375) 😔 🦑
Four steps to draw a North Atlantic Right Whale. 1) Start with basic shapes. 2) Add flipper shapes, mouth and eye. 3) Add facial features and markings. 4) Add details and shading.
