Acanthochondria Cornuta
''Acanthochondria cornuta'' is a species of parasitic copepod from the northeast Atlantic Ocean, and the type species of the genus ''Acanthochondria''. It infects the gills of several species of flatfish, particularly the European flounder ('' Platichthys flesus''). Copepodids and immature females infect the holobranch of the host, while adult females prefer the pseudobranch and the internal wall, suggesting they migrate upstream in the gills of the host as they mature. Reproduction Males in this species are several times smaller than the females, and attach themselves permanently onto special 'nuptial organs' on their mates. These organs are paired, and therefore a single female can sometimes hold two males. In Portuguese waters, reproduction happens year round, and at least two generations are seemingly produced per year, a summer-autumn generation, and a winter-spring generation. Females of the former are smaller and produce less eggs, while those of the latter are larger and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poecilostomatoida
Poecilostomatoida are an suborder of copepods. Although it was previously considered a separate order, recent research showed it to be nested within the Cyclopoida Description The classification of these copepods has been established on the basis of the structure of the mouth. In poecilostomatoids the mouth is represented by a transverse slit, partially covered by the overhanging labrum which resembles an upper lip. Although there is variability in the form of the mandible among poecilostomatoids, it can be generalized as being falcate (sickle-shaped). The antennules are frequently reduced in size and the antennae modified to terminate in small hooks or claws that are used in attachment to host organisms. Life cycle As with many crustaceans, larval development is metamorphic with immature forms differing greatly from those of adults. Embryos are carried in paired or single sacs attached to first abdominal somite (as seen in the illustration of the female '' Sapphirina darwinii ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
