- Title
- Trophic Ecology of the Slender Snipe Eel, Nemichthys scolopaceus (Anguilliformes: Nemichthyidae).
- Creator

- Abstract/Description
-
Roughly 92% of the total volume of Earth's oceans is considered deep sea. The eel species, Nemichthys scolopaceus, inhabits these waters, and little is known of its diet, its place within pelagic food webs, and its overall ecological impact. In this study we quantitatively estimate the abundance, feeding and predation impact of this key predator. Specimens were collected in 2004 along Georges Bank as part of the Census of Marine Life Gulf of Maine project. Gut contents were analyzed,...
Show moreRoughly 92% of the total volume of Earth's oceans is considered deep sea. The eel species, Nemichthys scolopaceus, inhabits these waters, and little is known of its diet, its place within pelagic food webs, and its overall ecological impact. In this study we quantitatively estimate the abundance, feeding and predation impact of this key predator. Specimens were collected in 2004 along Georges Bank as part of the Census of Marine Life Gulf of Maine project. Gut contents were analyzed, revealing thirteen prey types, primarily euphausiids and decapod crustaceans. Other potential prey (i.e. fishes) were absent from the diet, suggesting a fairly selective feeding preference. Of the 85 fish species collected, N scolopaceus ranked second in abundance and first in total fish biomass. Therefore, this species is not only a large biomass contributor, but perhaps cycles a great deal of macrocrustacean carbon through deep-pelagic fishes in this, and likely other, ecosystems.

- Abstract/Description
-
Atlantic spotted dolphins (Stenella frontalis) and bottlenose dolphins (Tursiops truncatus) are two sympatric species resident to the Bahamas. The visibility of the Bahamian water provided a unique opportunity to study spotted dolphin communication during aggression. This study’s main focus was to decipher any similarities or differences in the behaviors used by spotted dolphins during interspecific and intraspecific aggression. Both similarities and differences were discovered. Biting,...
Show moreAtlantic spotted dolphins (Stenella frontalis) and bottlenose dolphins (Tursiops truncatus) are two sympatric species resident to the Bahamas. The visibility of the Bahamian water provided a unique opportunity to study spotted dolphin communication during aggression. This study’s main focus was to decipher any similarities or differences in the behaviors used by spotted dolphins during interspecific and intraspecific aggression. Both similarities and differences were discovered. Biting, following, and chasing behavioral events were used more during interspecific aggression, while the display behavioral class was used more than the contact behavioral class during intrabut not interspecific aggression. This study showed that spotted dolphins use more energy intensive and risky behaviors when fighting interspecifically. This could result from having to fight and defend females from a larger species, trying to avoid sexual harassment from bottlenose males, or needing to use behaviors that are more overt and easily understood during interspecies communication.
