Sewing a Horseshoe Crab

Sewing instruction and cutting pattern designed by Conservation Sew Mates:  www.facebook.com/CSVsewmates
www.csvsewmates.com.hk;  Collaborating with Conservation Sew Mates, OPCFHK organised workshops for the public and students to make their own horseshoe crab plush toys.

Partnering with NGOs, Conservation Sew Mates conduct livelihood projects in the form of workshops for the local community in areas where conservation awareness is being introduced and developed. This creative process, which covers pattern making, cutting, sewing, stuffing and then selling is our way of encouraging participants to work together in generating revenue through ecotourism.

Horseshoe crabs have existed for 475 million years, since the Upper Ordovician period. We hope this fascinating marine creature will be around in another 475 million years.

The Count: Conserving Long Island’s Horseshoe Crabs

Leslie Von Pless, 2015.  http://wakemultimedia.com/2015/06/22/the-count-conserving-long-islands-horseshoe-crabs/   (11:25)

documentary on the process and significance of collecting data by surveying spawning horseshoe crabs on Long Island, including interviews with several researchers and citizen scientists;  emphasizes the critical connection of sustaining horseshoe crab populations to Red Knots, a shorebird species recently federally listed as “threatened” that depends on horseshoe crab eggs for food during its spring migration.

Horseshoe Crab Documentary

Nick Bakers “Weird Creatures” Series

Comprehensive, compelling and creatively-conceived look at horseshoe crabs from Nick Baker “Weird Creatures” series.  Using the unifying theme of its long evolutionary history of survival, the film brings in various HSC experts, along with extensive footage of spawning on Delaware Bay to explore interesting aspects of HSC anatomy, life cycle, ecology and importance to man.  Includes a nice piece about halfway through on the biomedical use of HSC blood, and another segment further along featuring HSC vision expert Dr. Bob Barlow describing the eyes.  The final third of the video documents the use of HSCs for bait and the key linkage HSC eggs provide to hemispheric shorebird migration. In closing, a strong case of concern is made for potential threats to that survival posed by human activities today.  (47:07)

It’s not an Alien! Meet the Horseshoe Crab.

Epic Wildlife

Quick & simple introduction to the anatomy, life cycle, ecology & values of the HSC from Epic Wildlife TV series.  Point of interest:  The opening shots of the strange wildlife form from Russia (that was used to justify the HSC for inclusion in the piece) is actually not an HSC at all (appears to be a Triops crustacean)!  (2:33)
