Birch Aquarium at Scripps Institution of Oceanography at UC San Diego recently announced the birth of ravioli-sized Big Skate babies. Visitors will soon have an up-close experience with these newborns of North America's largest skate species, as they are due to be moved from their nursery to other locations within the aquarium.
Big Skates are unique creatures. Their flat bodies and sandy coloration allow them to blend effortlessly into the seafloor, camouflaging themselves from potential predators. Furthermore, two large, black spots on their fins imitate oversized eyes, contributing to a larger and more intimidating appearance to fend off threats. Knowingly, they are harmless as they lack stingrays’ stinging barbs.
Despite not being listed as endangered by the International Union for the Conservation of Nature and Natural Resources (IUCN), Big Skates are vulnerable to overfishing due to their large size and slow growth rate. To mitigate this, Birch Aquarium participates in SAFE: Sharks & Rays, an Association of Zoos and Aquariums (AZA) initiative that promotes the protection of sharks, rays, and skates.
Conservation initiatives such as SAFE: Sharks & Rays play crucial roles in raising awareness about the dangers threatened species face. While the IUCN lists numerous species of skates and rays as "Least Concern," some, like the Barndoor Skate, previously faced endangerment due to overfishing. Stricter fishing regulations helped to revive the species that was at one point on the brink of extinction. This underscores the significance of sustainable management and conservation efforts in the survival of marine species.
