Sponge morphological plasticity has been a long-standing source of taxonomic difficulty. In the Caribbean, several morphotypes of the sponge Callyspongia vaginalis have been observed. To determine the taxonomic status of three of these morphotypes an

Consumer-mediated indirect effects at the community level are difficult to demonstrate empirically. Here, we show an explicit indirect effect of overfishing on competition between sponges and reef-building corals from surveys of 69 sites across the C

Symbioses often exist along a mutualism–parasitism continuum, and the classification of any given relationship requires a careful examination of costs and benefits for both symbiont and host. It has been proposed that deposit-feeding by the obligat

On coral reefs off the Florida Keys (USA), the obligate sponge-dwelling brittlestar Ophiothrix lineata lives almost exclusively in the tube sponge Callyspongia vaginalis. We examined chemotactic recognition by O. lineata to assess sponge host prefere

The structure of Caribbean coral reef communities has been altered by numerous anthropogenic and natural stressors. Demographic studies of key functional groups have furthered efforts to describe and understand these changes. Little is known, however

Fundamental theories of resource allocation for terrestrial plants predict that species investing in chemical defenses should be slow growing or less fecund, while undefended species should mitigate consumer effects by diverting energy to growth and

The Caribbean cirratulid polychaete, Cirriformia punctata (Grube, 1856), is bright orange and burrows just below the surface of fine carbonate sand with only its filamentous tentacles and gills exposed to potential predators. In addition to its consp

It is well documented that biotic effects play an important role in determining the distri- bution and abundance of sponges on Caribbean coral reefs: predation by fishes restricts some species to refugia, and allelopathic interactions result in a com
