Mighty, Mighty Horseshoe Crabs

Horseshoe Crabs: A Story of Beach Trysts and Blue Bloods comes to Island libraries.

Wildlife Abundance

Abundance is a difficult thing to judge. Changes to the abundance of a particular species are relative to our perception of its abundance when we first observe the species. Our first observations become our baseline against which we measure changes in our natural world. Is this appropriate? Consider horseshoe crabs.

Full Moon Fever, Chronicling Horseshoe Crab Couplings

At approximately 11:30 p.m. on Tuesday, June 25, the tide in Lake Tashmoo reached its highest point and began to roll back. Susie Bowman, a naturalist and teacher at Mass Audubon’s Felix Neck wildlife sanctuary, was there to mark the change with her husband, Woody. After Mrs. Bowman marked the tide’s apex, she began measuring out five-meter by five-meter quadrants in which they would search for pairs of mating horseshoe crabs. This is the couple’s fifth year of horseshoe crab surveying at Lake Tashmoo.

Kayakers Get an Intimate View Of Sengekontacket Pond’s Beauty

Leading a tour of the Sengekontacket, Felix Neck guide Emily Smith rounded Sarsons Island Friday in her red kayak and stopped. Something in the pond had caught her eye. She backtracked, peered into the water for a few moments and then pulled out a horseshoe crab. The kayakers on the tour crowded around for a look, bumping their boats together as they packed in. She flipped the crab over to show its small legs squirming in the air and began spelling out facts about the creature.

Mystery of the Missing Horseshoe Crabs

By the miracle of instinct and enormous exertion, a little bird, the red knot, migrates from the Canadian low arctic to the tip of South America and back each year.

But a decade or so ago, their number dropped dramatically. And the reason for it makes for one of those scientific detective stories that illustrates the interrelatedness of things to each other, and to us.

Fishermen Feud Over Horseshoe Crab Protection

Among all the species taken by fishermen in this part of the world, horseshoe crabs have, until now, enjoyed a dubious distinction: they were the only ones targeted while in the act of reproducing.

The easiest way for many to catch them was to walk the beaches at the times of the full and new moons in May and June and simply pick them up as they came into the shallows to spawn.
