Abstract:

Injuries to the hand by sea urchin spines are not commonly seen in the United Kingdom. There are many varieties of sea urchins (Echinoidea) throughout the world. They have a spherical calcium carbonate exoskeleton covered with spines. Certain varieties may be venomous, in particular the flower urchin ( Toxopneustes pileolus) found in the Indo-Pacific oceans. Injury may also be caused by the urchin spines or pedicellaria (delicate seizing organs equipped with jaws) ( Auerbach, 1991 ; Smith, 2002 ). A small number of hand injuries associated with sea urchin spines have been reported in the liter

Abstract:

Injuries caused by venomous and poisonous aquatic animals may provoke important morbidity in humans. The phylum Echinoderma include more than 6000 species of starfish, sea urchins, sand dollars, and sea cucumbers some of which have been found responsible for injuries to humans. Initial injuries by sea urchins are associated with trauma and envenomation, but later effects can be observed. Sea urchin granuloma is a chronic granulomatous skin disease caused by frequent and successive penetration of sea urchin spines which have not been removed from wounds. The authors report a typical case of sea

Abstract:

Sea urchins mineralize Mg-calcite skeletons, both, within their exoskeletons as well as in their spines. In this study we have investigated sea urchin spines of the species Amblypneustes pachistus. The spines are round and consist of several wedges that extend from the base to the tip of the spine. The wedges are connected to each other by porous calcite. Rocking curves of the spines show a distribution of 0.5° of the 110 reflection, with the domains being misoriented by 0.1° to each other. In our EBSD system the average mean angular (MAD) deviation is 0.3°. This is higher than the signal that

Abstract:

Neuromorphic engineering is the approach to intelligent machine design inspired by nature. Here, we outline possible robotic design principles derived from the neural and motor systems of sea urchins (Echinoida). Firstly, we review the neurobiology and locomotor systems of sea urchins, with a comparative emphasis on differences to animals with a more centralized nervous system. We discuss the functioning and enervation of the tube feet, pedicellariae, and spines, including the limited autonomy of these structures. We outline the design principles behind the sea urchin nervous system. We discus

Abstract:

Sea urchin aggregation is a common phenomenon in coastlines. However, it remains controversial whether sea urchins form resource aggregations or behavioral aggregations in a non-spawning season. To clarify, we studied the aggregative responses to food and predators in the sea urchin Mesocentrotus nudus when high fitness areas (HFAs) were scarce versus sufficient. By taking the occupied area of each sea urchin (test diameter + spines = 4.5 cm) as a square (4.5 cm × 4.5 cm), we set scarce HFAs for the sea urchins in Experiment 1 (the squares of HFAs: the area occupied by experimental sea urchins

Abstract:

Sea urchins, Echinoidea, are widely known for their defensive spines and pedicellariae, with some species having co-evolved venom in conjunction with those appendages. Despite this, their venomous arsenal remains poorly understood. Research has predominately focused on pedicellariae venom, while the spines have been largely neglected within studies. This review consolidates current knowledge of the venom systems (spines and pedicellariae) of sea urchins, focusing on the morphology, known venom components, and their functional effects. While early studies have established the bioactivity of cru

INTRODUCTION: Injuries caused by sea urchins are the most common caused by marine animals in humans in Brazil, with the black sea urchin (Echinometra lucunter) causing the most injuries to bathers. METHODS: This study observed 314 human wounds with emphasis on the early observation of clinical signs and symptoms and their implications on the recommended treatment. RESULTS: All the injuries were caused by black sea urchins and were observed in bathers. The lesions and the pain were associated with penetration of the spines; there was no early inflammation or pain without pressure on the wounded

Abstract:

Caribbean sea urchins are marine invertebrates that have experienced a decline over the years. Studies on sea urchins have focused primarily on the microbiome of the coelomic fluid or the gut microbiota. In this study, the epibiota community associated with four wild Caribbean sea urchin species, Lytechinus variegatus, Echinometra lucunter, Tripneustes ventricosus, and Diadema antillarum, was characterized for the first time. Using 57 sea urchin animal samples, we evaluated the influence of animal species, trophic niches, and geographical location on the composition of the epibiotic microbiota

Abstract:

Two species of sea urchins (Colobocentrotus atratus and Echinometra mathaei) commonly co-occur on wave-swept intertidal shores in the Indo West Pacific. E. mathaei is a typical spiny urchin and is confined to cavities in the rock. In contrast, C. atratus has an unusual morphology, in which the spines are much reduced, and is found on substrata fully exposed to wave-induced velocities and accelerations. Previous researchers have suggested that spine reduction may therefore be a morphological adaptation to hydrodynamic forces. However, measurement of the drag, lift and accelerational forces on s

Les couleurs vives observées dans les biominéraux provenant d'oursins adultes, allant du violet au vert, sont attribuées à la présence de molécules de naphtoquinone polyhydroxylée (PHNQs). Ces PHNQs sont intégrés dans la calcite, probablement au cours de la croissance cristalline, se produisant via l'intermédiaire de précurseurs de carbonate de calcium amorphe (ACC). La formation de minéraux chez les oursins s'accompagne de changements de couleur dépendant du stade de minéralisation.

The sea urchin Diadema antillarum is a keystone herbivore in the Caribbean and its functional extinction due to an epidemic in 1983 had a marked effect on coral reef health. Recovery of D. antillarum has been associated with improvements in reef health but has been unexpectedly slow and patchy with many populations persisting at low abundance on the reefs. This thesis investigates possible reasons for low and variable recovery of D. antillarum on the reef using combined techniques of population dynamic modelling, meta-analysis and field experimentation.

Abstract:

In Tasmania, arrival of the long-spined sea urchin (Centrostephanus rodgersii) has presented economic opportunity along with ecological change where they occur. Over the last half century, C. rodgersii has undergone climate driven range-extension and is now distributed along the entire east coast of Tasmania. The highest densities of C. rodgersii occur in northern Tasmania around the St Helens region and become less abundant along latitudinal gradients. This pattern of distribution has resulted in a developing fishery for C. rodgersii being mostly focused between ‘The Gardens’ and ‘St Helens I

Each group forms mineralized hard parts. In the Echinoidea the skeletal elements are fused together to form a rigid test, whereas in the Asteroidea, Ophiuroidea and Crinoidea the

Abstract:

“Respect for life” is a rallying cry among many animal rights activists. They target the use of animals in research, the wearing of fur coats, the hunting of wolves and whales, and more. They deplore, too, dissection in biology classes (essay 26). Ironically, in many of these high-profile cases, “respect for life” seems to mean not a universal respect for all life, but rather a narrow “respect for life-like-us.” The values seem associated primarily with mammals. A little knowledge of biology might broaden the scope of such sentiments, with perhaps some stunning consequences. We observe life in
