Calappa springeriVia\hhun, 1931.<br />

This species proved to be identical to C. sulcata Rathbun, 1898 when examined<br />

by Holthuis (1958) and so this name is a junior synonym. Rathbun's earlier<br />

description was based on a juvenile of the species and her later description, as<br />

C. springeri, was based on an adult form.. Many of the earlier Gulf of Mexico<br />

faunal surveys list C. springeri and these can all be referred to Calappa sulcata.<br />

Calappa sulcata Rathbun, 1898 (Bull. Lab. Nat. Hist. State Univ. Iowa 4: 289)<br />

Common Names: Yellow Box Crab; Shame-faced Crab; Parrot Crab.<br />

Range: North Carolina; Chesapeake Bight; Dry Tortugas; Alabama to south<br />

Texas; Tabasco, Mexico; Puerto Rico; Venezuela to Surinam; Amapa to Sergipe,<br />

Brazil.<br />

Depth: shore to 183 m (to 100 fm).<br />

Habitat: sand and sand-mud bottoms.<br />

Remarks: Listed from the Gulf of Mexico (some under C. springeri) by Chace<br />

(1956) and Fotheringham and Brunenmeister (1975), from Mississippi (Franks<br />

et al, 1972), and off Texas (Gunter, 1950; Hildebrand, 1954; Leary, 1967).<br />

Hildebrand (1954) reported ovigerous females from Texas in May and that<br />

claws of this crab were occasionally served at restaurants in Port Aransas. A<br />

report of mollusc shell-opening by this and other Calappa species (Shoup, 1968)<br />

provides one of the few behavioral studies. Listed from Chesapeake Bight by<br />

Musick and McEachran (1972) and from Brazil by Coelho and Ramos (1972).<br />

Habitat: sand, rock, coral, and shell bottoms; buries in sand.<br />

Remarks: Guinot-Dumortier & Dumortier (1961) described a stridulatory<br />

apparatus in this species and within the genus. Juvenile forms of this crab from<br />

Brazil were described by Rodrigues da Costa (1968b) and this species is also listed<br />

from Brazil by Coelho and Ramos (1972) and by Fausto Filho (1974).<br />
