Hydra is a genus of small, fresh-water organisms of the phylum Cnidaria and class Hydrozoa. They are native to the temperate and tropical regions. Biologists are especially interested in Hydra because of their regenerative ability — they do not appear to die of old age, or indeed to age at all.
Salamanders are a group of amphibians typically characterized by a lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All present-day salamander families are grouped together under the order Urodela. Salamander diversity is most abundant in the Northern Hemisphere and most species are found in the Holarctic ecozone, with some species present in the Neotropical zone.
The Sipuncula or Sipunculida is a group containing about 162 species of bilaterally symmetrical, unsegmented marine worms. The name Sipuncula is from the genus name Sipunculus, and comes from the Latin siphunculus meaning a "small tube". Traditionally considered a phylum, Sipuncula seems to be closely related to Myzostomida and Annelida, and may be a subgroup of Annelida, based on recent molecular work. Sipunculans vary in size but most species are under 10 cm (4 in) in length.
Onychophora, commonly known as velvet worms or more ambiguously as peripatus, is a phylum of elongate, soft-bodied, many-legged panarthropods. In appearance they have variously been compared to worms with legs, caterpillars, and slugs. They prey upon smaller animals such as insects, which they catch by squirting an adhesive slime.
Nuda is a class of ctenophores or comb jellies. The class contains a single family, Beroidae, with two genera, Beroe and Neis, and the group is more commonly referred to as the "beroids". They are distinguished from other comb jellies by the complete absence of tentacles, in both juvenile and adult stages. Beroe is found in all the world's oceans and seas, and the monotypic Neis occurs only near Australia; all beroids are free-swimmers that form part of the plankton.

Capas, officially the Municipality of Capas,, is a 1st class urban municipality in the province of Tarlac, Philippines. According to the 2015 census, it has a population of 140,202 people.
The broom hare is a species of hare endemic to northern Spain. It is restricted to the Cantabrian Mountains in northern Spain between the Serra dos Ancares and the Sierra de Peña Labra. This region is about 230 km (140 mi) from east to west and 25–40 km (16–25 mi) from north to south. It lives in mountains at elevations up to 2,000 m (6,600 ft), though it descends during the winter to avoid the colder temperatures and snow. Its preferred habitat is heathland, containing mainly Erica, Calluna, and Vaccinium, with much shrub cover of Cytisus, Genista, and Juniperus. It also inhabits clearings in mixed deciduous forests of oak and beech.
The Council of Australian Postgraduate Associations (CAPA) is the peak representative body for postgraduate students in Australia. CAPA's members are 33 postgraduate associations and the National Aboriginal & Torres Strait Islander Postgraduate Association (NATSIPA). CAPA provides member associations with representation to the Federal government, and peak bodies such as the Australian Research Council and Universities Australia, on issues affecting postgraduate students in Australia. In 2017, Australia had over 400,000 postgraduate students, representing one quarter of all tertiary students in Australia.
Scinax castroviejoi is a species of frog in the family Hylidae. It is found in valleys of the Eastern Andes in southern Bolivia, and controversially, in Argentina. Its type locality is Laguna de Bermejo. It is similar to Scinax fuscovarius but differs in call characteristics. The specific name castroviejoi honors Javier Castroviejo Bolívar, a Spanish zoologist.
An arthropod is an invertebrate animal having an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Euarthropoda, which includes insects, arachnids, myriapods, and crustaceans. The term Arthropoda as originally proposed refers to a proposed grouping of Euarthropods and the phylum Onychophora. Arthropods are characterized by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. The rigid cuticle inhibits growth, so arthropods replace it periodically by moulting. Arthopods are bilaterally symmetrical and their body possesses an external skeleton. Some species have wings.
Batoidea is a superorder of cartilaginous fish commonly known as rays. They and their close relatives, the sharks, comprise the subclass Elasmobranchii. Rays are the largest group of cartilaginous fishes, with well over 600 species in 26 families. Rays are distinguished by their flattened bodies, enlarged pectoral fins that are fused to the head, and gill slits that are placed on their ventral surfaces.
Amphilochus is a genus of crustaceans in the Amphipoda order, containing the following species:
Anguciana is a village in the province and autonomous community of La Rioja, Spain. It is situated in the northwest of the province. It depends on the judicial administration of Haro. The municipality covers an area of 5.05 square kilometres (1.95 sq mi) and as of 2011 had a population of 471 people.
Haplosyllis spongicola, the sponge worm, is a species of polychaete worm in the family Syllidae. It was previously classified as Syllis spongicola and is part of a species complex of closely related species that are difficult to distinguish morphologically and where the demarcation between them is unclear. It is found in shallow temperate, subtropical and tropical seas worldwide, wherever its host sponges are found.
Pionosyllis serratisetosa is a polychaete from the family Syllidae. The body of the worm exists as a head, a cylindrical, segmented body ending in a tail. The head consists of a prostomium and peristomium and a pair of appendages.
Erinaceusyllis, previously known as Sphaerosyllis, is a genus belonging to the phylum Annelida, a group known as the segmented worms. This genus consists of several species that were previously described as Sphaerosyllis and as Sphaerosyllis erinaceus sub-species, differing by the compound chaetae.
Syllis ramosa is a species of polychaete worm in the family Syllidae. It is found in the deep sea where it lives within the tissues of a sponge. It was the first branching polychaete worm to be discovered, with each worm having a single head and multiple anuses.
Syllis prolifera is a species of polychaete worm in the family Syllidae. It has a cosmopolitan distribution. It was first described in 1852 by the Russian/German zoologist August David Krohn who gave it the name Syllis prolifera.
Acromegalomma interruptum is a bristle worm from the Sabellidae family. The body of the worm consists of a head, a cylindrical, segmented body and a tailpiece. The head consists of a prostomium and a peristomium and carries paired appendages.
