“…Host colonisation in the marine realm is driven by stochastic mechanisms and it has been proposed as a major process that increases parasitic biodiversity when food resources overlap between actual and potential new hosts in evolutionary time (Gibson and Bray, 1994;Hoberg and Klassen, 2002;Palm and Klimpel, 2006;Raga et al, 2009). In fact, studies of several helminth taxa, including cestodes, nematodes and acanthocephalans, strongly suggest that the helminth fauna of cetaceans has resulted from host switching events (Hoberg, 1995(Hoberg, , 1997Mattiucci and Nascetti, 2008;García-Varela et al, 2013).…”

“…According to Raga et al (2009), female individuals of Pennella mainly burrow, generally on the back and belly of marine mammals to anchor their heads. In cetaceans vein vessels are more superficial in the back and abdominal parts for thermoregulation (Ponganis 2002).…”

“…Although other species of the genus are found embedded in the muscles of numerous marine hosts, Hogans (1987) reported that Pennella balaenopterae (Koren and Danielssen 1877) is the only species in this genus that parasitises marine mammals (Abaunza et al 2001). According to Raga et al (2009), Pennella species are probably transmitted to pelagic cetaceans from oceanic fish.…”

First report of infestation by a parasitic copepod (Pennella balaenopterae) in a harbour porpoise (Phocoena phocoena) from the Aegean Sea: a case report

An adult, female harbour porpoise (Phocoena phocoena relicta) was found stranded on the southern Aegean Sea coast of Turkey. Thirteen holes made by copepods were observed on the lateral sides of the porpoise. The copepods were identified as Pennella balaenopterae, based on the morphological characteristics and measurement. Tissue samples were collected from embedded parts of parasites, histopathologically examined and panniculitis findings were observed. Although this parasite copepod had been reported on several marine mammals, this is the first report in the harbour porpoise, and in the Aegean Sea.

“…was based on molecular sequencing of the cox1 gene and did not allow for morphological identification to species level. Species of Bolbosoma are one of the two acanthocephalan genera known to parasitize marine mammals (Raga et al 2009). Euphasiids and copepods act as first intermediate hosts (Hoberg et al 1993, Gregori et al 2012, and fishes act as paratenic or transport hosts (Raga et al 2009).…”

Mesopelagic fishes represent significant ecological links between mesozooplankton and the larger pelagic squids, fishes, and marine mammals. As such, these fishes also play a significant role as intermediate or paratenic hosts for parasites that require a crustacean intermediate host and mature in marine mammals or pelagic fishes. We examined a total of 208 individuals representing 5 species of Sternoptychidae and 88 individuals representing 2 species of Phosichthyidae from 20 locations in the northern Gulf of Mexico (nGOM). Six of the 7 species we examined are mesopelagic and one species was benthopelagic. We found the larval stages of Anisakis brevispiculata, Anisakis typica, Hysterothylacium fortalezae (all Nematoda: Ascaridoidea); Bolbosoma sp. (Acanthocephala: Polymorphidae); and Tetraphyllidea (Cestoda) plus an immature specimen of Brachyphallus sp. (Digenea). Molecular sequencing was used to identify the ascaridoids and Bolbosoma sp. and to confirm the identification of 3 host sternoptychid species. The mesopelagic fishes hosted Anisakis brevispiculata (that matures in pygmy and dwarf sperm whales) and Hysterothylacium fortalezae (that matures in pelagic fishes, primarily mackerels), whereas the benthopelagic species was parasitized by Anisakis typica (that matures in dolphins). We suggest this pattern of infection indicates a pelagic life-cycle for Anisakis brevispiculata and Hysterothylacium fortalezae and a demersal life-cycle for Anisakis typica. Our study represents the first published sequences from the nGOM for the fishes Argyropelecus aculeatus, Maurolicus weitzmani, and Polyipnus clarus and the first molecular identification of larval ascaridoids from mesopelagic fishes in the nGOM.
