Description

Timarete punctata sp. A is an infaunal polychaete of the family Cirratulidae. The anterior portion of the body is thickened, but tapered and elongated posteriorly, with a shallow ventral groove. Branchiae resembling strands of spaghetti, extend from all the segments of the body, and are longer on the anterior and middle portions of the body. The prostomium is broad and triangular, and bluntly pointed. Eyes are absent. The peristomium is short, aproximately 1.5 X the length of the prostomium, with two annulations. Tentacular filaments, in groups of 5 are present on chaetigers 3 and 4. Notopodia and neuropodia are poorly developed all along the body. In chaetigers 1-10, branchiae arise just dorsal to the notopodia, but from chaetigers 10-26, they originate closer to the midline of the body. From chaetigers 26 to 42, they move closer to the notopodia,and continue just above the notopodia to the end of the body. Capillary chaetae are present on the notopodium and neuropodium of each chaetiger. Acicular spines, about 1/3 the length of the capillary chaetae, and somehat sigmoid and hook-like, occur first on the neuropodia of chaetiger 6 and on the notopodia of chaetiger 8. Anterior chaetigers bear three acicular spines, and two capillary chaetae on the notopodia and three acicular spines and two capillary chaeta on the neuropodia. The middle chaetigers, bear two acicular spines, and two capillary chaetae on the both the notopodia and neuropodia. Posterior chaetigers have one acicular spine, and one capillary chaeta on the notopodia, and two spines and one capillary on the neuropodia. The pygidium is triangular, and the anal opening is placed dorsally (Cinar 2007). The largest specimen reported was 50 mm with 70 chaetigers, from South Africa. The body of preserved worms is light to dark brown, with black spots on the body, and black bars on the branchiae and tentacles (Day 1967; Cinar 2007; Seixas et al. 2017). Living worms of species A have bright yellow branchiae, and tentacles, with black bars only on the tentacles. Species B has black bars on both the tentacles and branchiae (Seixas et al. 2017).

Molecular analysis indicates that there are two cryptic species under the name Timarete punctata, one of which (species A.) is widely distributed around the world, with very little genetic diversity (Seixas et al. 2007). The type specimen of Timarete punctata was collected by Grube from Christiansted, St. Croix, in the Virgin Islands in 1845 (Cinar 2007). Worms apparently of this species, are known from the tropical Atlantic, Pacific, and Indian Oceans. A genetic survey found that T. punctata species A, was found in Panama, several sites in Brazil, and Hawaii. Sepcies B was found only in Bahia, Brazil (Seixa set al. 2020).

Ecology

General:

Timarete punctata is a marine cirratulid polychaete, most often assoicated with soft sediments, but also found in fouling communtiies and rocky habitats (Cinar 2007). The mode of sexual reproduction is poorly known, though oocytes were found in one specimen. Asexual reproduction through fission and fragmetation is common.. Cittatulid polychaets are associated with soft sediments, but are also found on hard calcarous bottomd, and among tunicates, barnacles, mussels, and sponges in fouling communities (Cinar 2007; Seixas et al. 2017). The specimens in Cevik harbor were found in an old tire (Cinar 2007). Cirratulids are known to be deposit-feeders (Fauchauld and Jumars 1979). Accumulated sediment, feces, and pseudofeces in fouling communtiies are a potential source of food.
