About Lindaspio polybranchiata

Lindaspio polybranchiata is a species of polychaete worm in the family Spionidae. It is known for its unique multiple branchial filaments, which aid in respiration and feeding. This species is typically found in deep-sea environments, often inhabiting soft sediments where it constructs burrows. Like other spionids, it uses its specialized palps to collect organic particles from the surrounding water and sediment, serving as a deposit feeder. Its adaptations to low-oxygen environments and its role in benthic ecosystems make it an important species for studying deep-sea biodiversity and ecological processes.

Original Name

Lindaspio polybranchiata Sui, Dong, Wu & Li, 2023

Key Reference Paper

1. Sui J, Dong D, Wu X, et al.  A new species of the genus Lindaspio Blake & Maciolek, 1992 (Annelida, Spionidae) from a cold seep near Hainan Island, China[J]. ZooKeys, 2023, 1153: 105. (Sui et al., 2023)

Description

Total length 55 mm, maximum width 4 mm, including chaetae. More than 350 crowded chaetigers. Color pale in alcohol. Prostomium incised, developed into two frontal lobes or weak horns; caruncle present or absent; occipital tentacle absent. Peristomial wings absent. Notopodia of chaetigers 2–4 with fascicles of heavy spines. Anterior neuropodial spines present. Dorsal branchiae starting from chaetiger 2; ventral branchiae starting from an anterior segment, branchiae closely associated with parapodial lamellae, continuing to posterior end. Chaetiger 1 reduced, with notopodia reduced to single lamellae lacking notochaetae. Following notopodia and neuropodia with capillaries and hooded hooks. Pygidium simple, conical, lacking cirri.

Etymology

The species is so named because it has more neuropodial branchiae than the congeners.
