Greenland Sharks Are in Can't Get Enough Shark Stuff by Kelly Hargrave

Summary: Greenland sharks are in Can't Get Enough Shark Stuff by Kelly Hargrave and Andrea Silen even as Arctic thaw affects them as climate change therein.

"God talks to human beings through many vectors: through each other, through organized religion, through the great books of those religions, through wise people, through art and music and literature and poetry, but nowhere with such detail and grace and color and joy as through creation. When we destroy a species, when we destroy a special place, we're diminishing our capacity to sense the divine, understand who God is and what our own potential is." Robert Francis Kennedy Jr., April 19, 2023, Boston Park Plaza Hotel, Back Bay, Boston, Massachusetts.

“And there’s many people out there who want us to move to the next planet already and I’m like, hang on, let’s not give up on this planet yet," William, Prince of Wales, July 31, 2023, Sorted Food food truck, London, England, United Kingdom.

The Irminger Sea, a marginal sea of the North Atlantic Ocean located east of southern Greenland, the Reykjanes Ridge, a northern part of the Mid-Atlantic Ridge located near southwestern Iceland, favor Greenland shark pupping sites, according to Julius Nielsen, a Greenland shark specialist and marine biologist with the Department of Fish and Shellfish, Greenland Institute of Natural Resources, Nuuk, Greenland, and with the History Museum of Denmark, University of Copenhagen, Copenhagen, Denmark, in "Spatial Distribution of Greenland Shark Somniosus microcephalus (Bloch & Schneider, 1801) Life Stages Across the Northern North Atlantic," a research article with 14 co-authors published in Ecology and Evolution, volume 15, issue 7 (Jul 2025; https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece3.71564); Nielsen et al. also identified Skagerrak, a strait located between North Jutlandic Island (Danish: Nørrejyske Ø; northernmost continental Denmark), the east coast of Norway and the west coast of Sweden as connector of the North Sea with the Kattegat sea; Nielsen et al. considered ". . . only the deepest parts of Skagerrak (> 400 m), which connect to the continental shelf break, . . . and not the much shallower inner waters of Denmark and Sweden" as potential, suitable nursing habitats for Greenland sharks; "Caption: Greenland shark from NW approx. 2.5 m caught and released from the Greenland Institute of Natural Resources' research vessel RV Sanna in the area around Uummannaq, NW Greenland.

Greenland sharks are in Can't Get Enough Shark Stuff by Kelly Hargrave and Andrea Silen, for National Geographic Kids, even as Arctic thaw affects them as climate change and as Greenland thaw.

Co-authors Kelly Hargrave and Andrea Silen begin their book with a world map where "supercold" (Hargrave/Silen"18) waters of Arctic and North-Atlantic Oceans bathe Greenland sharks. Arctic-Ocean cold, dark depths call Greenland sharks to Baffin Island and coastal-north Greenland and to waters north of coastal-north Iceland and north-archipelagic Norway and European Russia. The coastal waters off eastern North America and coastal-eastern Baffin Island; Greenland; Iceland; United Kingdom; coastal-north Europe; Norway; coastal-northeast Finland; and European Russia domicile Greenland sharks.
