Depth: shore to 331 m (to 170 fm).<br />
Habitat: from hard bottoms (shell, rock, or coral); usually carries a sponge<br />
or compound ascidian over the dorsal carapace. Uncommon to rare in many<br />
Gulf areas, but Hildebrand (1955) reported this crab as common on the pink<br />
shrimp grounds of Campeche, Mexico, in 6 to 16 fm (11 to 29 m) of water.<br />
Remarks: Rathbun (1937) reported ovigerous females in winter, spring,<br />
and summer from Florida and the West Indies, and she also listed specimens<br />
with infestations of bopyrid parasites. Williams (1965) noted crabs that carried<br />
zoanthoid polyps; specimens from Alligator Harbor in northwest Florida carried<br />
the ascidian, Eudistoma capsulatum (Wass, 1955). Regional lists include<br />
Florida (Dragovich and Kelly, 1964; Abele, 1970; Menzel, 1971), Mississippi<br />
(Franks et al, 1972), Texas (Hildebrand, 1955; Parker, 1959; Leary, 1967),<br />
and Mexico (Hildebrand, 1955). Felder (1973a) indicates that this species is<br />
common on Seven and One-Half Fathom Reef, off Texas; Chace (1956) listed<br />
this species from several Gulf stations of the R/V Oregon. Listed from French<br />
Guiana by Guinot-Dumortier (1959) and from Brazil by Coelho and Ramos<br />
(1972). Larval development under laboratory conditions was studied by Rice<br />
&Provenzano (1966).<br />

Range: North Carolina to southern Florida; Dry Tortugas; west coast of Florida<br />
; St. Thomas, Virgin Islands; Surinam to ELspirito Santo, Brazil.<br />
Depth: 2 to 40 m (1 to22fm).<br />
Habitat: sand and shell substrates. Williams (1965) notes that this species is<br />
always found with a lamellibranch mollusc shell, usually a clam, which it carries<br />
over its back by its claws and fourth and fifth walking legs.<br />
Remarks: Listed from Florida by Wass (1955), Dragovich and Kelly (1964),<br />
Abele (1970), and Menzel (1971). Kircher (1970) studied larval development<br />
under laboratory conditions.<br />

Range: off North Carolina; Florida Keys and Dry Tortugas; off Texas; Jamaica;<br />
Guianas; Moranhao to Bahia, Brazil.<br />
Depth: 1 to 90 m (to 49 fm).<br />
Habitat: from sand, shell, and coral bottoms; Williams (1965) states that the<br />
habits of this crab are similar to those of H. arcuata, but that it is a much rarer<br />
species.
