Abstract A new assessment of the global biodiversity decapod Crustacea (to 31 December 2022) records 17,229 species in 2,550 genera and 203 families. These figures are derived from a well-curated dataset maintained on online platform DecaNet, subsidiary World Register Marine Species (WoRMS). Distinct phases recognised discovery process (as measured by descriptions) corresponding to major historical geopolitical time periods, with current rate descriptions being more than three times higher...
The evolution of symbiotic relationships involving reef corals has had much impact on tropical marine biodiversity. Because their endosymbiotic algae (zooxanthellae) can grow fast in shallow seas where they form reefs that supply food, substrate and shelter for other organisms. Many coral symbionts are host-specific, depending particular species existence. Some these animals have become popular objects underwater photographers aquarists, whereas others hardly noticed or considered pests....
Botanical and zoological collections may serve as archives for historical ecological research on the effects of global change human impact coral reef biota. Museum harbour old specimens reef-dwelling species that have become locally extinct. Such also help to determine whether early records invasive can be obtained from times when they were not yet recognized such. A case study (2006) involving Saba Bank, Caribbean Netherlands (former Antilles), suggests fauna here impoverished compared with...

The ninth assigned to genus. It can be separated congeners by anterolateral orientation cornea, carapace shallow transverse depressions, lacking longitudinal smooth dorsal margin fifth female pereiopod carpus. distinctive...
Fluorescence is a notable adaptation in marine environments, helping to counteract the loss of longer wavelengths as light diminishes with depth. Studied some extent cnidarians and reef fish, its presence functions crustaceans are less understood. Recently, fluorescence was discovered gall crabs (Cryptochiridae). To investigate evolutionary significance these coral-dwelling decapods, we combined multivariate examination 27 fluorescent morphological traits phylogenomic analysis across 14 crab...
ABSTRACT Species' occurrence rates are the backbone of many ecological studies. Sampling species occurrence, however, can come with challenges and might prove more difficult than anticipated. Logistical difficulties, limited funds or time, elusiveness rarity sampling environments all examples scenarios that contribute to (undesired) small sample sizes. In order help circumvent some these difficulties uncertainties, we present SAMPLE, an R package aims inform user whether amount conducted up...
Coral-associated invertebrates dominate the biodiversity of coral reefs.Some associations involving symbiotic remain unknown or little studied.This holds true even for relatively wellstudied reefs, like those in Caribbean Sea.Coral gall crabs (Cryptochiridae), obligate symbionts stony corals, form a much-overlooked component reef communities.Most recent studies on Atlantic members Cryptochiridae have been conducted off Brazil and data become available from region.During fieldwork Curaçao...
In order to demonstrate how scleractinian corals contribute marine biodiversity by their host function, information on associated fauna was gathered during a biological survey at St. Eustatius, eastern Caribbean. This knowledge is especially urgent for coral such as Helioseris cucullata (Agariciidae), which has undergone strong declines in abundance various Caribbean localities and poor record of fauna. New records H. are presented the gall crab Opecarcinus hypostegus (Cryptochiridae),...
Layang-Layang is a small island part of an oceanic atoll in the Spratly Islands off Sabah, Malaysia. As reef coral fauna this South China Sea poorly known, survey was carried out 2013 to study species composition scleractinian families Fungiidae, Agariciidae and Euphylliidae. A total 56 recorded. The addition three previously reported brings 59, consisting 32 22 Agariciidae, five Of these, are new records for Layang-Layang, which include rarely species, i.e., fungiids Lithophyllonranjithi,...
Abstract Gall crabs are obligate associates of stony corals in which they induce skeletal modifications. In some cryptochirid species, females live open depressions accessible to males; while others, rather isolated semiclosed galls, necessitates elaborate sperm storage capabilities by the female. this study we investigate female gross morphology and reproductive systems Fungicola syzygia lodged flattened pits, Opecarcinus cathyae with semiopen pits Pseudocryptochirus viridis from shallow...
The enigmatic gall crab family Cryptochiridae has been proposed to be phylogenetically derived from within the Grapsidae (subsection Thoracotremata), based on analysis of 16S mtDNA one cryptochirid, Hapalocarcinus marsupialis, among a wide array thoracotremes, including 12 species Grapsidae. Here, we test monophyly and phylogenetic position using same gene, but with an extended representation cryptochirids spanning nine in eight 21 genera, addition further thoracotreme representatives....
Abstract Coral‐associated fauna is a relatively understudied topic. Hence, the nature of relationship between an associated organism and its host usually unknown. In present study, obligate associations gall crabs (Decapoda: Cryptochiridae) mushroom corals (Scleractinia: Fungiidae) are reviewed from phylogenetic perspective. Based on field surveys, examination museum material literature review, total 35 fungiid species have been found that act as hosts for four crab species....
Mushroom corals of the Indo-West Pacific Fungiidae (Scleractinia) provide habitats for a rich associated fauna, including three species gall crabs (Cryptochiridae). During course present study were sampled from many different fungiid hosts. Based on this ‘reversed’ approach - by studying coral symbionts host perspective previously unnoticed specificity pattern was detected. The sampling crab fauna per combined with molecular analyses H3 nDNA, 16S and COI mtDNA revealed cryptic closely...
Photosynthetic animals produce oxygen, providing an ideal lens for studying how oxygen dynamics influence thermal sensitivity. The algivorous sea slug Elysia viridis can steal and retain chloroplasts from the marine alga Bryopsis sp. months when starved, but chloroplast retention is mere weeks they are fed another green alga, Chaetomorpha To examine plasticity in tolerance changes net exchange starving, slugs each were acclimated to 17°C (the current maximum temperature which exposed nature)...
Abstract Coeloplanidae, the largest family of benthic ctenophores, comprises 33 species, all described based on traditional morphological characteristics, such as coloration, length, and number aboral papillae, which are highly variable can be affected by fixation methods environmental conditions. Thus, there is a need for reliable genetic markers to complement identifications at species level. Here, we analyzed 95 specimens from 11 morphologically distinct ctenophores Red Sea Sulu Sea,...
The Phyllidiidae (Gastropoda, Heterobranchia, Nudibranchia) is a family of colourful nudibranchs found on Indo-Pacific coral reefs.
