Cucullanus bulbosus, scanning electron microscopy. Cucullanus bulbosus is a species of parasitic nematodes. [1] [2] It is an endoparasite of carangid fishes.In 1916, Lane [1] described a new cucullanid species, Bulbodacnitis bulbosa, from the bluefin trevally Caranx melampygus off Sri Lanka and established the new genus Bulbodacnitis to accommodate it, because he considered the presence of a ...
Enoplea (enopleans) is a class, which with the classes Secernentea [1] and Chromadorea make up the phylum Nematoda in current taxonomy. [2] [3] [4] The Enoplea are considered to be a more ancestral group than the Chromadorea, and researchers have referred to its members as the "ancestrally diverged nematodes", compared to the "more recently diverged nematodes" of Chromadorea.
The nematodes (/ ˈ n ɛ m ə t oʊ d z / NEM-ə-tohdz or NEEM-; Ancient Greek: Νηματώδη; Latin: Nematoda), roundworms or eelworms constitute the phylum Nematoda. Species in the phylum inhabit a broad range of environments. Most species are free-living, feeding on microorganisms, but many are parasitic.
The Vedda minority in Sri Lanka may become completely assimilated. [6] Most speak Sinhala instead of their indigenous languages, which are nearing extinction. It has been hypothesized that the Vedda were probably the earliest inhabitants of Sri Lanka and have lived on the island since before the arrival of other groups from the Indian mainland ...

Another theory is that the nittaewo could have been a Sri Lankan population of Negritos, a race native to the Philippines who are about 2 in (51 mm) shorter on average than the Veddahs, who he suggests may have inhabited Sri Lanka before the arrival of the Veddahs. South and Southeast Asia were subject to a great number of racial migrations ...
In the Vedda people of Sri Lanka it reaches its highest frequency of 13.33% (subclade U7a). It is speculated that large-scale immigration carried these mitochondrial haplogroups into India. [26] Chaubey states that "considerable number of maternal lineages of Sri Lanka is shared with India, more precisely with southern part of India." [27]
This is a list of reptiles of Sri Lanka. The reptilian diversity in Sri Lanka is higher than the diversity of other vertebrates such as mammals and fish with 181 reptile species. All extant reptiles are well documented through research by many local and foreign scientists and naturalists.
