Ophichthid eel species are abundant and diverse in tropical and semi-tropical seas but there are few studies of snake eel life histories and factors influencing spatial distributions. Here we analyze 12 demersal longline sampling expeditions circumnavigating continental shelves in the Gulf of Mexico (GoM) during 2011-2017. Two Ophichthid eels were dominant components of fish assemblages: king snake eel (KSE), Ophichthus rex, and palespotted eel (PSE), Ophichthus puncticeps. Relative abundance (CPUE) of KSE was highest in the north central GoM, lower in the northwest and southeast and on the West Florida Shelf, and absent from northwest Cuba and the Yucatán Platform. Contrariwise, PSE abundance was highest on the Yucatán Platform, lower in the north central GoM and on the West Florida Shelf, and absent from the northwest and southwest GoM and Cuba. GAM-based species distribution models were fit to presence-absence data from sampled stations using a variety of environmental covariates including water depth, longitude, and sediment type (sand vs mud/silt). Although the two species were caught in similar depths and bottom temperatures, they were only caught together at 1% of the stations. This study extends the record length of KSE to 226 cm (total length). Despite being abundant in areas overlapping the footprint of the Deepwater Horizon oil spill in 2010, concentrations of polycyclic aromatic hydrocarbons (PAHs) and their metabolites were relatively low in KSE, perhaps related to copious slime production which, in other studies, has been determined to be a vector for PAH excretion in fishes.ResumenLas especies de anguilas ofictidas son abundantes y diversas en los mares tropicales y semitropicales; sin embargo existen pocos estudios sobre las historias de vida de las anguilas serpiente y los factores que influyen en sus distribuciones espaciales. En este estudio analizamos 12 expediciones de muestreo con palangre demersal desarrolladas en la plataforma continental de todo el Golfo de México (GoM) durante 2011-2017. Dos anguilas Ophichthid fueron componentes dominantes en los conjuntos de peces: lairón (KSE), Ophichthus rex, y tieso de puntos pálidos (PSE), Ophichthus puncticeps. La abundancia relativa (CPUE) de KSE fue más alta en el centro norte del GoM, menor en el noroeste y suroeste y en la plataforma del oeste de Florida, y nula en el noroeste de Cuba y la plataforma de Yucatán.

热带和半热带海域蛇鳗种类丰富多样，但对蛇鳗生活史及其空间分布影响因素的研究较少。在此，我们分析了2011-2017年在墨西哥湾(GoM)环绕大陆架进行的12次海底延绳钓取样考察。两种蛇鳗是鱼类组合的优势组成部分:王蛇鳗(KSE)，蛇鳗(Ophichthus rex)和白斑鳗(PSE)，蛇鳗(Ophichthus puncticeps)。KSE的相对丰度(CPUE)在墨西哥湾中北部最高，在西北、东南和西佛罗里达大陆架较低，在古巴西北部和Yucatán台地不存在。相反，PSE丰度在Yucatán平台最高，在墨西哥湾中北部和西佛罗里达大陆架较低，在墨西哥湾西北部和西南部以及古巴没有。基于gam的物种分布模型使用多种环境协变量(包括水深、经度和沉积物类型(沙vs泥/淤泥))拟合采样站的存在-缺失数据。虽然这两个物种在相似的深度和底部温度被捕获，但它们只在1%的站点被捕获。本研究将KSE记录长度延长至226 cm(总长)。尽管在2010年深水地平线漏油事件的重叠区域中，多环芳烃(PAHs)及其代谢物的浓度相对较低，但在KSE中，多环芳烃(PAHs)及其代谢物的浓度相对较低，这可能与丰富的黏液生产有关，而在其他研究中，黏液已被确定为鱼类排泄多环芳烃的载体。黄鳝种类丰富多样，有热带和亚热带两种;在美国发行的电影空间中，有许多电影工作室，包括电影制作厂、电影制作厂、电影制作厂和电影制作厂。在2011-2017年期间，对12个观测数据进行了分析，结果表明该观测数据是在陆地上发现的。Dos anguilas Ophichthid fueron components dominantes en los conjuntos de peces: lairón (KSE)， Ophichthus rex, y tieso de puntos pálidos (PSE)， Ophichthus puncticeps。La abundancia relativa (CPUE) de KSE fue mas阿尔塔在埃尔森特罗北▽傻子,menor en el noroeste suroeste y en La组织。这个组织oeste de佛罗里达,y nula en el noroeste古巴y de La组织de尤卡坦半岛。这个组织贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家，贫穷国家。Los modelos de distribución de especies basados en GAM se ajustaron和Los datos de presciia -ausencia de las estaciones必须利用的数据和co变量的环境变量包括la prodididad del agua, la longitude和el tipo de sedimento (arena frente a lodo/limo)。独特的葡萄品种在葡萄的温度和葡萄的相似度上都有显著的变化，单独的葡萄品种占葡萄品种的1%。Este estudio extenende la longitude máxima registrada de KSE长226厘米(总经度)。2010年1月1日，在深海地平线上发现了大量的碳氢化合物(HAP)，并发现了与KSE相关的代谢物(HAP)，发现了与producción相关的微生物(HAP)，发现了与其他研究机构相关的微生物(HAP)，发现了与excreción相关的多环芳烃(PAH)载体(bp)。

Indo-Pacific sun corals (Tubastraea spp.) are aggressive competitors capable of disrupting the structure and function of natural reef habitat in the western Atlantic. Sun corals observed on rope debris entangled on an artificial reef in the Florida Keys suggest a potential dispersal mechanism for the colonization of natural reef habitat.

Through variance decomposition, we investigated the impact of the rate of development and utilization intensity of coastal areas and the economic and industrial structure and spatial location on the environmental quality of seawater. The water quality of coastal waters of Liaodong Bay was evaluated using the comprehensive water quality evaluation index, Nemerow index, and principal component analysis. Dalian and Huludao were found to have significantly better water quality than Panjin, Yingkou, and Jinzhou near the Liaohe Estuary. Marine functional areas and seawater quality index were spatially correlated, and the intensity of sea area development and utilization had a significant positive correlation with the comprehensive evaluation index of seawater quality and Nemerow index. The per capita gross domestic product of coastal cities and seawater quality index followed an “inverted U-shaped” Kuznets curve. Variance decomposition analysis showed that the intensity of sea area development and utilization cumulatively explained 42.3% of the changes in the quality of the seawater environment, while the economic and industrial structure cumulatively explained 31.8%. The direct impact of the intensity of development and utilization of the sea area and the economic and industrial structure contributed 16.5%, while interaction between the natural geographical location and sea area development and utilization intensity and economic and industrial structure cumulatively explained 58.9% of the changes. Our results strongly support management and control of sea reclamation, comprehensive management of coastal waters, and optimization of coastal industrial structure to improve the environmental quality of coastal waters.

Soft coral (Octocorallia: Alcyonacea) farming has been widely used to decrease the fishing pressure on wild populations harvested for use in the ornamental trade and studies related to natural products. With a soft and flexible body, only a few attempts have been made to quantify the growth rate, either in the field or in aquarium systems. In this study, the planar area measurement approach was applied and evaluated for its applicability to soft corals. All fragments of Sinularia penghuensis and Cladiella hartogi were placed on individual tiles (10 × 10 cm) and randomly distributed in the mesocosm. Two treatments were applied: (1) finger touch treatment, and (2) air exposure for one minute to avoid the influence of morphological flexibility caused by the hydroskeleton before taking photographs underwater. Two independent tests were carried out including (1) applying two treatments before taking photographs for four sides (only for S. penghuensis), and (2) comparing the planar area and linear measurement with its dry weight (for both species). Since the shape of C. hartogi is stable through time, the first test was not required for C. hartogi. The photographs were taken twice per day (11:00am and 8:00pm), and five pictures were taken for each side. The results showed that there was no significant difference between one and five pictures used (P > 0.05). Furthermore, taking photographs of two sides that are perpendicular to each other is recommended to provide sufficient statistical power. Meanwhile, the air treatment made the fragments less flexible during the photographing process which should be used in this standardized 2D image analysis. Our results also showed that planar area was strongly correlated (P < 0.001) with its dry weight (R2 = 0.929 for S. penghuensis and R2 = 0.945 for C. hartogi). In addition, the air exposure treatment was consistently similar during both times (daytime and nighttime). Based on the results, we suggest this standardized 2D method to measure the growth of soft corals by measuring planar area changes through time.

In the southeastern Pacific off Chile, coralliophilid snails have only been cited from offshore islands at the Juan Fernández Archipiélago and from Easter Island. In this work we describe a new coralliophilid species, Coralliophila ceciliae sp. nov., from shallow subtidal waters at a few locations in the Región de Atacama, northern Chile. This new species represents the first record for the subfamily Coralliophilinae, and for the genus Coralliophila, in the coasts of continental Chile. The new species differs from all other known eastern Pacific Coralliophila species in terms of shell shape, thickness, aperture color, and sculpture details, and it represents the first report of a coralliophilid species associated with actiniarians in the eastern Pacific.ResumenEn el Pacífico suroriental frente a Chile, caracoles coralliophilidos solo han sido citados de islas oceánicas en el archipiélago de Juan Fernández y en la Isla de Pascua.

The Atlantic horseshoe crab, Limulus polyphemus , is an ecologically and commercially important species occurring across the south and northeastern coast of the United States. However, populations of this species are experiencing declines due to overcollection, use as bait, and other anthropogenic factors. Citizen science holds great potential as a useful complementary tool to traditional monitoring efforts, so we evaluated horseshoe crab observations uploaded to the citizen science platform iNaturalist. Across 10,094 observations, the majority of which occurred primarily during summer months, the number of observations increased annually from 2008 to 2022, presumably as this platform is gaining popularity in overall use by citizen scientists. Analyzing a subset of images from this dataset, we found evidence of scavenging, ranges in the number of individuals, and additional organisms (mollusks or barnacles) attached to specimens, with 52.7% live versus 38.9% dead, and most images showing a complete specimen (61.6%) and adult life stages (80.3%). Most observations were taken on sand (75.7%), with some in shallow water (9.4%) or in vegetation (7%). We recommend researchers incorporate this freely available database as a complementary conservation tool to document presence and natural history and to monitor population trends both in this species and other marine species.

The historic thesis of Albin O Ebersbach (1887–1915), describing the internal and external anatomy of cirrate octopods Grimpoteuthis and Stauroteuthis, is herein translated to enable its important morphological insights into cirrate octopods to be better accessed and appreciated by the teuthological community. A biography of Ebersbach is briefly covered, and the identification of his specimens is discussed, given apparently overlooked morphological details of his specimens including the presence of a distinct radula and posterior salivary gland in his Grimpoteuthis material. Additional taxonomically informative states in cirrates are needed, and as a result of this translation additional internal morphological details are proposed that may be of systematic importance.

Albin O Ebersbach(1887-1915)的历史论文描述了环状章鱼Grimpoteuthis和Stauroteuthis的内部和外部解剖结构，本文对其进行翻译，以使其对环状章鱼的重要形态学见解能够更好地被动物学界获取和欣赏。简要介绍了Ebersbach的传记，并讨论了他的标本的鉴定，考虑到他的标本明显被忽视的形态学细节，包括在他的grimpotethis材料中存在一个独特的radula和后唾液腺。在cirrates中需要额外的分类信息状态，并且由于这种翻译，提出了可能具有系统重要性的额外内部形态学细节。随着非侵入性成像技术的使用增加，这些状态的评估可能越来越实用。

A biography of Ebersbach is briefly covered, and the identification of his specimens is discussed, given apparently overlooked morphological details of his specimens including the presence of a distinct radula and posterior salivary gland in his Grimpoteuthis material. Additional taxonomically informative states in cirrates are needed, and as a result of this translation additional internal morphological details are proposed that may be of systematic importance.

In the Caribbean Sea and adjacent areas, squids of the genus Abralia are a key component in the cephalopod community. However, the distribution and abundance of their paralarvae in this region are unknown, as well as their morphology in early development, making their identification difficult. In this study, paralarvae of Abralia spp. from surface Neuston, subsurface Neuston, and multiple opening and closing nets and environmental sensor system (MOCNESS) (0–58 m) tows carried out in the Caribbean Sea were identified, describing the horizontal and vertical distribution of their abundance and their morphology and molecular identity. The greatest abundance of Abralia spp. was recorded in subsurface tows, distributed mainly off Chinchorro Bank, Cozumel, and Honduras, and in a stratum of 38–48 m depth in MOCNESS tows. Paralarvae showed evidence of ontogenetic migration with larger sizes distributed at greater depths. Sixty eight percent of Abralia spp. had sizes of 1.1–2.0 mm mantle length (ML), indicating that the Mesoamerican Barrier Reef System is an important area in the spawning and development of the genus. Fourteen paralarvae were sequenced using the Cytochrome Oxidase I gene (COI) resulting in the presence of two species: Abralia redfieldi and Abralia veranyi (99.01%–100% similarity), which could not be individually identified using the morphological analysis. However, we confirmed their geographical overlap along the Caribbean Sea and described the general morphology of the paralarvae between 1.1–6.0 mm ML.

Once one of the predominant reef-building corals in the region, Acropora cervicornis is now a focal species of coral restoration efforts in Florida and the western Caribbean. Scientists and restoration practitioners have been independently collecting phenotypic data on genets of A. cervicornis grown in restoration nurseries. While these data are important for understanding the intraspecific response to varying environmental conditions, and thus the potential genetic contribution to phenotypic variation, in isolation these observations are of limited use for large-scale, multi-institution restoration efforts that are becoming increasingly necessary. Here, we present the Acropora cervicornis Data Coordination Hub, a web-accessible relational database to align disparate datasets to compare genet-specific performance. In this data descriptor, we release data for 248 genets evaluated across 38 separate traits. We present a framework to align datasets with the goal of facilitating informed, data-driven restoration throughout the Caribbean.
