The Horseshoe Crab Network

Did you know?

Horseshoe CrabsThe horseshoe crab, Limulus polyphemus, at one time were considered true crustaceans, thus the name "crab." However, these dark brown Arthropods are only distantly related to such crustaceans as the true crabs, shrimps and lobsters. By examining their underside, we can clearly see many similarities between the horseshoe crabs, members of the class Merostomata and spiders, scorpions and ticks, which belong to the class Arachnida.

There is recent concern that a species that has been in existence for over 350 million years may be in jeopardy. The Horseshoe Crab habitat covers the coast of Maine to Florida, with Long Island and Fire Island normally hosting a large population. There is expert concern about a significant decline in the horseshoe crab population over the past decade.

The Horseshoe Crab Network (HSC) headed by Dowling College's Dr. John T. Tanacredi, will conduct a Super-inventory of the horseshoe crab population and YOUR HELP is urgently requested.

Anyone sighting a horseshoe crab is asked to call the HSC Hotline at 631-244-3394

Callers should leave their name, address, telephone number and the time of call and a representative of the HSC network will meet them to view the HSC habitat, count the crabs, measure them and record the site on a regional map of Horseshoe Crab habitats.
