Plumularia setacea (Linnaeus, 1758). are identified as a species of Hydrozoans belonging to the family Plumulariidae[1]. Better known as 'Glassy Plume Hydroid' The species plumularia setacea are sometimes also know as ‘little sea-bristles[2].’  They are a colony of polyps that can get up to 15cm in height[3]. While not harmful, they can produce a mild sting on bare skin[4]. They have a very wide spread distribrution, globally and can be found almost anywhere[5]. They are distinguishable by their feather-like appearance[6], not to be confused with the species Kirchenpaueria similis[6], which is very similar.

General Description

edit

First discovered in 1758 by Linnaeus[1], the sessile marine hydroid Plumularia setacea is a single species belonging to the Plumularriidae family[1]. Genetic diversity within the species is high but widely dispersed, with numerous similar species. Characterized by its feather-like appearance, it features a brown central stem with alternating forms of side branches[6]. The colonies are connected by stolons at the base of the species[4].

These branches vary. One being a longer joint, which is made up of hydrotheca and nematothecae. The shorter branch consists only of nematophores[6]. Along the side of one of the side branches are the feeding polyps, which are attached directly[3]. These hydroids lack a medusa stage[7] and are primarily benthic. The colonies form a flat, two-dimensional plane, with a potential height of up to 15cm[3].

Ecology

edit

Plumularia setacea are a marine species. Plumularia setacea are nearly cosmopolitan[8] as they are widely dispersed and have a high tolerance to environmental conditions. The species is mainly found in tropical to temperate waters[9], usually at depths of 1–30 meters. They can be found almost everywhere besides the Arctic and Antarctic oceans.

The species has been recorded in the north-east Atlantic, British Isles, South America, Norway, New Zealand, and Southern Australia[7]. Commonly found in coastal habitats and can be abundant in semi-sheltered areas[4].

Reproduction

edit

Typically, colonies of the species become sexually mature in the spring and summer but are the most fertile in July. Normal months of breeding for this feather-like hydroid are June to September and once colonies reproduce, they die[7]. Along the main stem of the species ,there are polyps in the hydrothecae[9]. They have gonothecae. Notably, the gonothecae exhibit sexual dimorphism, with those of male are narrower and smaller than their female counterparts[9].

The species Plumularia setacea are gonochoristic and produce larvae rather than eggs[2]. The sperm swim from the male gonophores to the gonophores of the female, faciliting reproduction of the species[2].

Feeding

edit

Most hydrozoans are filter feeders, as are the species, Plumularia setacae. They mainly feed on zooplankton or particles[4]. They are a carnivorous species[7].
