Space poddity

The short-beaked common dolphin, Delphinus delphis, is one of the most wide spread and abundant dolphin species in the world. They're known to be especially social, energetic, and may live in large groups (pods) of a few hundred individuals. The common dolphin will sometimes form "mega-pods", in which thousands of individual dolphins will band together for a time [1]. The short-beaked common dolphin is known to go "bow-riding" alongside waves made by boats, and even some large whales [2].

Today we share the chromosome-length genome assembly for the short-beaked common dolphin, Delphinus delphis! This genome assembly was generated using the $1K strategy with a contig N50=50Kb and a scaffold N50=89Mb. The sample for this genome assembly was provided to us by Barbie Halaska, from The Marine Mammal Center in Sausalito, California. As the world’s largest marine mammal hospital, the Center prides itself on gathering and providing open research data that is free to access, reuse, repurpose and redistribute in service to ocean conservation and marine mammal health. Learn more about the impact of The Marine Mammal Center’s scientific research by visiting the Center's website.

This sample was collected by The Marine Mammal Center under the Marine Mammal Health and Stranding Program (MMHSPR) Permit No. 18786-04 issued by the National Marine Fisheries Service (NMFS) in accordance with the Marine Mammal Protection Act (MMPA) and Endangered Species Act (ESA). The work at DNA Zoo was performed under Marine Mammal Health and Stranding Response Program (MMHSRP) Permit No. 18786-03.
