Elysia crispata displays variable morphology and coloration; and while intensity of the green pigmentation is due, at least in part, to the diet of the animal (Pierce et al., 2006; Curtis et al., 2007, 2015), the reasons for variation in other characters relating to the foot, parapodia, radula, digestive tubule morphology, habitat tolerances, as well as secondary blue, yellow, orange, and pink colorations, are unknown but likely have genetic components.
Oval-shaped body, about 30 setiger; elytra 15 pairs, with scattered papillae; prostomium with globular ocular lobes; facial tubercle present; long median ante nna with ceratophore; long palps with small scattered papillae; tentacular cirrus long and thin; dorsum without or with very few felted notosetae, elytra visible; harpoon-shaped notosetae absent; notosetae long, notosetae all smooth, of two kinds: stout, smooth sabrelike, long, curved over dorsum and fine capillary setae; neurosetae of anterior few segments with extra teeth, some bipinnate; ventral surface and parapodia covered with globular papillae (Amaral & Nonato, 1982).
The venue of the inauguration, the Ekiti Parapodia Pavillion, constructed by Fayemi in his first tenure from 2010 to 2014, has been decorated and arrangements made for a smooth movement of dignitaries and invited guests to the arena, at New Iyin Road.
Biramous parapodia with a dorsal cirrus longer than ventral cirrus, both filiform.
Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin.
Median parapodia (Figure le) with capillary setae only, 6-9 in the notopodium and 6-11 in the neuropodium, those of the posterior row longer, uniformly thinner, very slender (3-4 [micro]m) and less hirsute, as long as body width.
Nereis virens Solitary worms, elongated with well-developed parapodia. Measures ~40-50 mm in length.
There are many examples of this strategy, such as the expansions of echinoderm larvae, the appendages and prolongations of decapod crustacean larvae, molluskan parapodia and the feathery appendages of many crustaceans.
The new species is characterized, and differs from other species of the genus mainly by the location of the first pair of branchiae, by having dichotomously branched branchiae in the mid-posterior chaetigers, the absence of subpodial papillae and the morphology of the parapodia.
An attempt was categorized by typical sperm donor behavior, in which the head and anterior portion of the foot lean forward between the recipient's parapodia (Leonard and Lukowiak, 1986); however, penis intromission was not observed after the 15 to 30-minute mating period.
In parapodia, chaetae are more abundant and lobes almost equal (to each other)].
