Gnathonemus translates into string jaw, while petersii is for someone named Peters. (Wikipedia says possibly Wilhelm Peters).
Fun Fact: “Gnathonemus petersii is a demersal species that occurs close to the bottom where it probes for food with the long snout. Territorial and usually aggressive towards members of its own species. This behaviour has been shown to involve electric organ discharge (EOD) activity.” (IUCN)
Habitat: They are endemic to freshwater river ways of the Congo Basin in Central Africa.
Ecosystem Role: They help control populations of aquatic invertebrates.
Cebus means a monkey, while apella appears to translate to without skin
Fun Fact: “Cebus apella can be found in mixed species groups. They are most often found in association with squirrel monkeys (Saimiri sp.). Usually the squirrel monkeys initiate the mixed group interaction, probably in order to find food more efficiently. Squirrel monkeys follow brown capuchin monkeys to new food sources, which saves them foraging time. The association does not seem to benefit capuchin monkeys.” (ADW)
Habitat: They are endemic to rainforests and montane forests from Columbia and Venezuela to northern Argentina.
Ecosystem Role: They help spread seeds with their diet of mostly fruit, but they do consume other vegetation, eggs, and small vertebrates and invertebrates. They provide food for hawks and eagles (like the harpy eagle), and more than likely the jaguar as well.
Clethra means the alder, while alnifolia translates into alder leaf.
Fun Fact: They have a sweet and spicy smell when in bloom, and attract butterflies.
Habitat: They are endemic to woodlands and swamps on the Atlantic Coast from Nova Scotia to Florida.
