A green chiton attached to a half crab. We observed this alien looking commensal beast while undertaking an intertidal survey on the reefs off Hawera. It made us jump when we first turned over the rock.

I believe this is the first sighting of this plant in St. Mary’s County MD (Precise coordinates are available on request).

Location: A small plateau about 5m above & 10m horizontal to an estuary.

Habitat: A small stand of Pinus virginiana within a dense thicket of Kalmia latifolia, with isolated Quercus bicolor, Quercus falcata (I think), Ilex opaca, and Acer sp. nearby contributing to the leaf litter.

Other Notes: If my nose is to be believed there are at least 3 more populations within a few hundred meters. The odor is similar to cloves, but less spicy and more floral.

Distinctive off-center, puffy spout on the horizon had us flying full tilt despite swells. Yee-haw! Got two nice looks at this rare visitor, with a 40-minute dive in between. Second photos show tooth rake marks on body, perhaps another sperm whale being social or orca or ? This could very well be the same individual first spotted on Oct 1 by the Blackfin out of Monterey - @leptonia on board: http://www.inaturalist.org/observations/4253161

What a treat. Thank you Kate, Jim, and the entire Blue Ocean Whale Watch crew.

UPDATE: This is apparently the 4th sighting of this individual since Oct 1.

This is a picture of Stenocorus cylindricollis at the Hilton Area of Patapsco Valley State Park in Baltimore County, Maryland.

Cap: Highly reflexed as if folded upward in half. 4-1/2 inches at widest, 2" at narrowest, surface dry, soft, rubbery, cream color with brown patches, appearing partially translucent in some areas. Margin free of gills about 1/16" and folded in and out.Gills: Dark brown, very close, adnexed, covered in small particles of sand, edge appears to glow gold in some photosStalk: 1-1/4" long with 1-1/4" bulb, total stalk and bulb length 2-1/2".Stalk covered with brown scales, darker at top, flaring slightly at gills. Annulus at top of bulb, white, papery thin with ragged edges, one piece 1/2" long. Bulb pointed w/o apparent mycelium.Strong mushroomy odor. Stipe turns bright meat-red instantly when cut, then dull brown. Context color unchanging when cut. Context and cap unchanging in KOH, Ammonia, and FeSO4. Alkalis prevented red reaction on cut stipe.The following observations (with herbarium specimens)from same location: http://mushroomobserver.org/79686?q=1XDLN (2011-10-16)http://mushroomobserver.org/112572?q=1XDLN (2012-10-06)http://mushroomobserver.org/113628?q=1XDLN (2012-10-16)http://mushroomobserver.org/116165?q=1XDLN (2012-11-08)

NUMBER: 20221107
SPECIES: Blue Crab, Callinectes sapidus Rathbun, 1896[1]
COLLECTION: Commercial crabbing by Craig Miller
BILATERAL GYNANDROMORPH: Half male (Fig. A, Left), half female apron (Right), blue-tipped male claw (left), and red-tipped (female) claw (right).[2] Lemaitre and Reed (2013) noted 3 bilateral gynandromorph (half female, half male) specimens from Virginia in 1979, Chesapeake Bay (Otto, 1979), and northern Gulf of Mexico in 2005, (Louisiana?). Only one was scientifically reported (Otto, 1979). Cargo (1980) noted 1 from Chesapeake Bay; Johnson and Otto (1981) found normal female and male organs and that the specimen bred as a female and as a male; Fahrenthold (2005) reported 1 from Gwynns Island, lower Chesapeake Bay, 21 May 2005; Pollitt (2021) reported 1 from Chesapeake Bay. Thus far 7 specimens have been reported, 5 from Chesapeake Bay, 1 from nearby in Virginia, and 1 from the northern Gulf of Mexico, possibly Louisiana. The number in Chesapeake Bay is skewed by the intense fishing pressure, attention, and interest there. Two other species of crabs, other crustaceans, butterflies, and birds are known to have this condition.

[1]Identification was peer-reviewed, text edited and condensed. The entire, original text is in our available reprint [710]. [2]A genetic chimera is a single organism composed of cells with more than one distinct genotype. In animals, this means an individual derived from two or more zygotes, which can include possessing subtle variations in form (phenotype). Animal chimeras are produced by the merger of multiple fertilized eggs. Often considered minor curiosities, but Williamson (2013) considers them responsible for the origins of major groups of animals.
