Common spider crab (Libinia emarginata)

Common spider crab (Libinia emarginata)

While working in Pleasant Bay in Chatham last week, I saw numerous pairs of common spider crabs (Libinia emarginata) in the shallow water. Spider crabs have quite a different look from other local crabs. Their carapace is rounder with a distinctive beaklike protrusion. Their eight walking legs and two claws are long and narrow giving them a very spider-like appearance. This species is also called “nine-spined spider crab” due to the nine spines, or bumps, running down the center of…

Smooth Cordgrass (Spartina alterniflora)

Smooth Cordgrass (Spartina alterniflora)

Visit a salt marsh anywhere in Massachusetts and what you’ll see is an assemblage of grass species, largely indistinguishable from each other to the casual passerby. Although difficult to tell apart from a distance, and sometimes difficult even up close when their flowers or seeds are not present, salt marshes are generally comprised of a variety of species. One of the most common, however, is smooth cordgrass (Spartina alterniflora). S. alterniflora grows 2 to 6 feet high and is typically…

Beach plum (Prunus maritima)

Beach plum (Prunus maritima)

Beach plums (Prunus maritima) are best known for the fruits they produce in August/September, which are popular in jams and jellies, but they are most easily spotted this time of year, even from a distance, due to their showy displays of bright white flowers. The flowers bloom in May before the leaves emerge. Although these short, densely-branched beach plum shrubs appear rather scraggly-looking prior to leafing out, they will soon fill in with alternate, simple, approximately 2 inch long leaves…

River herring

River herring

Saturday morning I stopped at the Mashpee River fish ladder by the Mashpee Wampanoag Indian Museum on Route 130 to see if the herring were running yet. To my delight, they were. The Mashpee River is approximately four miles long and flows from Mashpee-Wakeby Pond to Popponesset Bay, and then out into the Atlantic Ocean. Each spring, two species of river herring, alewives (Alosa pseudoharengus) and blueback herring (Alosa aestivalis), make their way from the sea back to Mashpee Pond…

Ring-billed gull (Larus delawarensis)

Ring-billed gull (Larus delawarensis)

Gulls are often the most abundant and visible coastal birds, regardless of the season. This is largely because they are remarkably successful at adapting to different environments and are opportunistic feeders. In the winter, ring-billed gulls (Larus delawarensis) are one of the most common gulls in Massachusetts, perhaps even outnumbering Herring gulls and Black-backed gulls. They can be distinguished from these other two species as being the smallest of the three, and adult ring-billed gulls have a fairly short, slim…

Little Skate (Leucoraja erinacea)

Little Skate (Leucoraja erinacea)

On a recent walk along Scusset Beach along Cape Cod Bay, the wrack line was dotted with four-pronged, dark-brown, leathery pouches. These pouches, sometimes called “mermaid’s purses”, “devil’s purses” or “sailor’s purses” are actually skate egg cases. Although many species of skate and shark lay similar egg cases, based on the size, shape and location where they were found, these dried black leathery cases are likely from the Little Skate (Leucoraja erinacea). Little Skates can be found from Nova Scotia…

Wildflower Wednesday: Seaside Goldenrod

Wildflower Wednesday: Seaside Goldenrod

Winter doesn’t mean the end of wildflower identification. Many plants retain easily identifiable seed pods and other features. Although the late summer display of its vibrant yellow flower clusters is over, seaside goldenrod (Solidago sempervirens) is no less interesting in December. Seaside goldenrod is a native perennial aptly named as it is commonly found in dunes and at the edges of salt marshes. It is fairly well adapted to drought conditions, allowing it to survive in the dry, sandy dunes….

Eastern red cedar (Juniperus virginiana)

Eastern red cedar (Juniperus virginiana)

Despite its name, the eastern red cedar (Juniperus virginiana) is actually a species of juniper rather than cedar. Eastern red cedars have two types of leaves depending on the age of the tree and/or the branch. Young shoots and seedlings have predominantly prickly leaves, while mature trees and branches have tightly overlapping scale-like leaves. In fertile soil, eastern red cedars can grow up to 60 feet tall, in a regular conical shape. In sandy soil common to coastal Cape Cod,…

Sanderling (Calidris alba)

Sanderling (Calidris alba)

Although many shorebirds are only found in the Arctic during the breeding season, with the onset of fall, many will start appearing along the Massachusetts coast. One example of this is the sanderling (Calidris alba). Sanderlings are long-distance migrants, breeding only on the far northern Arctic tundra, while dispersing to almost all sandy beaches of the world during the winter, including Cape Cod. Sanderlings are medium sized sandpipers and have fairly distinctive nonbreeding plumage: white belly and breast with grey…

Common Glasswort (Salicornia maritima)

Common Glasswort (Salicornia maritima)

While tall grasses, like Spartina alterniflora, dominate the more frequently flooded lower elevations of a salt marsh, the high marsh areas, which are inundated less frequently, are home to an entirely different and interesting set of plants.  Glassworts, in particular, are exceptionally colorful this time of year. Many people focus on the changing colors of the leaves of various deciduous trees as autumn arrives, but glassworts put on their own colorful fall display. Although almost completely green throughout the spring…
