Abstract:
Understanding the growth dynamics of an organism is central to understanding its ecology and biology. Sponges often dominate many subtidal habitats, however, determining their growth dynamics is often difficult owing to the plastic and amorphous morphologies that occur in many species. Two sympatric Haliclonid sponge species were examined using a novel photogrammetric technique to understand how environmental and competitive influences affect their growth. Sponges of both species were tagged and monitored over a 14-month period. Haliclona sp. 1 (green Haliclona) showed little variation in grow

Abstract:
Two new marine sponges, Haliclona ieoensis sp. nov. and Haliclona sumenyoensis sp. nov. from the south Korea are described. Morphologically distinct from each other, both species are assigned to the genus Haliclona subgenus Haliclona. Haliclona ieoensis sp. nov. individuals are thickly encrusting to massive, beige colour and have small oscules flush on surface. Haliclona sumenyoesis sp. nov. individuals have a cylindrical tube with flexible stalk morphology, ivory colour, and large oscules. The description of these two new species brings the species of Haliclona (Haliclona) in Korea to five.

Abstract:
Two new marine sponges, Haliclona (Reniera) oceanus sp. nov. and Haliclona (Reniera) juckdoensis sp. nov. of the family Chalinidae were collected from Ieodo Ocean Research Station, Ulleung-do Island, Korea by SCUBA in 2016-2017. Morphologically distinct from each other, both species are assigned to the genus Haliclona subgenus Reniera. Haliclona (Reniera) oceanus sp. nov. is similar to H. (H.) ieoensis Kim et al. 2017 in shape, habitat, growth form, but it differs in color, ectosomal, choanosomal skeleton and spicule size. Haliclona (Reniera) juckdoensis sp. nov. is similar to H.

Abstract:
Marine sponge genus Haliclona, one of the most prolific sources of natural products, contains over 600 species but only a small part of them had been classified and chemically investigated. On the basis of extensive literature search, this review firstly summarizes 112 nitrogenous secondary metabolites from classified and unclassified Haliclona sponges as well as from their symbiotic microorganisms. Most of these substances have only been found in Haliclona sponges, and display diverse bioactive properties with potential applications in new drug discovery.

Abstract:
[Truncated abstract] Sponges have an invaluable ecological importance through the provision of shelter and habitat, consolidation of reefs, bio-erosion, and in benthic-pelagic coupling processes. In addition, sponges are known to be an incredible source of compounds with bio-medicinal and commercial applications. Despite their ecological and economic importance, our understanding of the processes which maintain and structure sponge populations is severely lacking compared to other sessile invertebrates (e.g. Cnidarians). This study examines the processes which help maintain and the factors whi
