The relationship between sea cucumbers (Holothuriidae) and pearlfishes (Carapidae) is a relatively unknown system. In this study, we set out to answer questions regarding the nature of this relationship; i.e. parasitic, mutualistic or commensal. The Holothuridae species we studied were Thelenota ananas and Bohadschia argus and the Carapidae species we examined were Encheliophis Boraborensis and...

Two new triterpene glycosides, scabraside A (1) and B (2), and a structurally known compound (3), were isolated from the sea cucumber Holothuria scabra (Holothuriidae) collected from the South China Sea. Structure of these compounds was elucidated by spectroscopic and chemical methods. The glycosides 1 and 2 exhibit the same common structural features, i. e., the presence of 12- and 17-hydroxy ...

Marine reserve networks have become important tools for mitigating these pressures, and one of the most critical factors in determining their spatial design is the degree of connectivity among different populations of species priorit...
