The sea- sonal timing of reproduction and aspects of the settlement and development of brooded offspring are reported. Precise locality data extend the bathymetric range to waters as shallow as 10 m, and the geographical range east to the Avalon Peninsula (Newfoundland, Canada). We differentiate it from other known northern, externally brooding species of sea anemone. Morphological characters, including verrucae, decamerous mesenterial arrangement, and non-overlapping sizes of basitrichs in tentacles and actinopharynx, agree with a generic diagnosis of Urticina Ehrenberg, 1834 rather than Epi- actis Verrill, 1869. Key words: Brooding, Epiactis, Epigonactis Introduction Since its original description in 1899 based on two preserved specimens, no subsequent collection of the species currently known as Epiactis fecunda (Verrill, 1899) has been reported in the literature, nor have details of its life history nor descriptions of the live animal. -

DEVANEY,3 and BARRY ROTH 4 ABSTRACT: Anatomy and cnidae distinguish two species of deep-sea ac tinians that produce coiled, chitinous shells inhabited by hermit crabs of the genus Parapagurus. The actinian type species, Stylobates aeneus, first assigned to the Mollusca, occurs around Hawaii and Guam with P. dofleini. Stylobates cancrisocia, originally described as Isadamsia cancrisocia, occurs off east Africa with P. trispinosus.

As such, they are essential components of neuromuscular and neuronal systems, and are targeted by toxins from a wide variety of phyla, including the cnidarians.

A. radians n. sp. is characterized by a yellow-whitish and brown checkerboard-like pattern on the oral disc, adhesive verrucae along the entire column and a series of marginal projections, each bearing a brightly-colored acrorhagus on the oral surface. This is the seventh species of Anthopleura described from the South Pacific Ocean; each one distinguished by a particular combination of differences related to their coloration pattern, presence of zooxanthellae, cnidae, and mode of reproduction. Some of these species have not been reported since their original description and thus require to be taxonomically validated. -

The giant Caribbean sea anemone, also called the pink or purple-tipped anemone, as well as giant golden anemone has a distinct purple or pink colour at the tip of its tentacles (Zahra, n.d.) (Fig. 1). Contrastingly, behind its tip straight down to its base, the tentacles are brown or greenish in colour. This organism may possess either male or female reproductive organs, or more rarely both (hermaphrodite). Its size is estimated at 15cm high and 30cm wide with a disc as wide as approximately 40cm (Wikipedia, 2015). This large column-shaped animal has 100 or more tentacles (free floating) around its mouth which is hidden at the centre of all the tentacles on an oral disc, leading to the gastrovascular cavity. Cnidocysts (stinging organelles that inject poison) are present in the tentacles (Hickman et al., 2002, 119). The basal disc is UWI The Online Guide to the Animals of Trinidad and Tobago Ecology firmly connected to the substrate causing the organism to be sessile or fixed into location (Zahra, n.d). The giant Caribbean sea anemone lacks a medusa (jellyfish-like) stage in the life cycle. DISTRIBUTION.

They are a colourful and diverse group, and we hope you enjoy using this guide to explore them further and identify them in the field. ADORABLE ANEMONES is a fully illustrated working e-guide to the most commonly encountered shallow water species of Actiniaria, Corallimorpharia, Ceriantharia and Zoantharia, the anemones of New Zealand. It is designed for New Zealanders like you who live near the sea, dive and snorkel, explore our coasts, make a living from it, and for those who educate and are charged with kaitiakitanga, conservation and management of our marine realm. It is one in a series of e-guides on New Zealand Marine invertebrates and algae that NIWA’s Coasts and Oceans group is presently developing. The e-guide starts with a simple introduction to living anemones, followed by a simple colour index, species index, detailed individual species pages, and finally, icon explanations and a glossary of terms. As new species are discovered and described, new species pages will be added and an updated version of this e-guide will be made available. Each anemone species page illustrates and describes features that will enable you to differentiate the species from each other. -
Sea Anemone (Cnidaria, Anthozoa, Actiniaria) Toxins: an Overview

Received: 31 May 2012; in revised form: 9 July 2012 / Accepted: 25 July 2012 / Published: 22 August 2012 Abstract: The Cnidaria phylum includes organisms that are among the most venomous animals. The Anthozoa class includes sea anemones, hard corals, soft corals and sea pens. The composition of cnidarian venoms is not known in detail, but they appear to contain a variety of compounds. Currently around 250 of those compounds have been identified (peptides, proteins, enzymes and proteinase inhibitors) and non-proteinaceous substances (purines, quaternary ammonium compounds, biogenic amines and betaines), but very few genes encoding toxins were described and only a few related protein three-dimensional structures are available. Toxins are used for prey acquisition, but also to deter potential predators (with neurotoxicity and cardiotoxicity effects) and even to fight territorial disputes. Cnidaria toxins have been identified on the nematocysts located on the tentacles, acrorhagi and acontia, and in the mucous coat that covers the animal body. -
