Eulimids (Gastropoda, Eulimidae) on the Sea Cucumber Holothuria mexicana (Ludwig, 1875) (Holothuroidea, Holothuriidae) in Belize [PDF]
This study presents new records for 4 eulimid species (Gastropoda, Eulimidae) including Melanella eburnea (Megerle von Mühlfeld, 1824), Melanella hypsela (Verrill & Bush, 1900), Melanella sp., and Eulimostraca encalada Espinosa, Ortea ...

A Holothurian Triterpene Glycoside Holothurin A (= Echinoside A) Isolated From the Starfish
A triterpene glycoside identified as holothurin A 2 (= echinoside A) was isolated from the extract of the tropical starfish Choriaster granulatus and identified by extensive nuclear magnetic resonance (NMR) spectroscopy and electrospray ionization (ESI ...

Qualitative and Quantitative Saponin Contents in Five Sea Cucumbers from the Indian Ocean
To avoid predation, holothuroids produce feeding-deterrent molecules in their body wall and viscera, the so-called saponins. Five tropical sea cucumber species of the family Holothuriidae were investigated in order to study their saponin content in two ...

Holothuria leucospilota Population in Satang Besar Island, Sarawak, Malaysia
Holothuria leucospilota or locally known as “Patola” is currently considered the most abundant sea cucumber species in Malaysia. This coral reef‐dwelling species is not in danger of extinction in comparison to commercial sea cucumbers such as “gamat.” However, overfishing activities in addition to lack of fishing regulations in Malaysia could put this ...

Asexual Reproduction in Holothurians
Aspects of asexual reproduction in holothurians are discussed. Holothurians are significant as fishery and aquaculture items and have high commercial value. The last review on holothurian asexual reproduction was published 18 years ago and included only 8 species.

The stone fish (Actinopyga lecanora) ethanolic and methanolic tissue extracts were investigated for total phenolic contents (TPCs) as well as antioxidant activity using 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH•) radical scavenging activity and ferric reducing antioxidant power (FRAP) assays. Both extracts showed low amount of phenolics (20.33 to 17.03 mg of
