Acrochaetlum spp. Species of Acrochaetlum of uncertain identity 



were frequently found as epiphytes on larger algae and seagrasses 

 as well as on rock on the reef and the algal plain. Randall 

 (1967) recorded Sparisoma rubripinne and Melichthys niger as 

 consumers of Acrochaetium sp. 



Acrochaetlum sargassi B^rgesen. Found once on Gracilaria cylindrica 

 in 22 m depth 30 m from the face of the reef. Originally 

 described from the Virgin Islands. 



Amphiroa fragilissima (Linnaeus) Lamouroux. Occasionally mixed with 

 other algae on the algal plain in 15 to 20 m depth. Randall 

 (1964) found this species in the stomach contents of the queen 

 conch, Strombus gigas , and (1967) in the following fishes: 

 Abudef duf taurus , Acanthurus chirurgus , A. coeruleus , Alutera 

 scripta , Balistes vetula , Blennius cristatus , Cantherhines 

 macrocerus , C^. pullus , Eupomocentrus fuscus , E^. variabilis , 

 Melichthys niger , Ophioblennius atlanticus , Scarus coelestinus , 

 S^. guacamai . 



Asterocystis ramosa (Twaites) Gobi. Occasional as an epiphyte on 

 larger algae ( Laurencia , Acanthophora , Lobophora , Sargassum ) 

 on the algal plain in 15 to 23 m depth, and found once on Udotea 

 in a seagrass bed ( Syringodium ) in 10 m depth. Randall (1967) 

 found this species in the stomach contents of Blennius mar mo reus 

 and Eupomocentrus fuscus . 



Callithamnion byssoides Arnott in Hooker. Found on Chrysymenia 



enteromorpha and Gracilaria cylindrica on the algal plain in 

 20 m depth, and once on Syringodium in 10 m depth. Randall 

 (1967) found Callithamnion sp. in the stomach contents of 

 Ophioblennius atlanticus , and the queen conch, Strombus gigas 

 (Randall, 1964). 



Centroceras clavulatum (C. Agardh) Montagne. Occasional throughout 

 the algal plain as an epiphyte on Gracilaria cylindrica, 

 Halimeda incrassata , Udotea conglutinata , and on shell in 15 

 to 20 m depth, and found once at the base of a coral head on 

 the reef, once as an epiphyte on Syringodium in 10 m depth. 

 Taylor (1960) reported this species from shallow water to at 

 least 20 m depth. Randall (1964) found _C. clavulatum in the 

 stomach contents of the queen conch, Strombus gigas . In 1967 

 he reported this species in the diet of the following fishes: 

 Abudefduf taurus , Acanthurus bahianus , A. chirurgus , A. 

 coeruleus , Cantherhines macrocerus , Eupomocentrus fuscus , E^. 

 planifrons , Diplodus caudimacula , Micro spa thedon chrysurus , 

 Pomocanthus paru , Scarus croicensis and S_. guacamaia . He 

 further reported Centroceras sp., almost certainly C^. clavulatum , 

 from Scarus coelestinus , S^. croicensis , S_. taeniopterus , S_. 

 vetula , Sparisoma aurofrenatum , S_. rubripinne , and S^. viride .
