Common Name: Hawaiian Chub Scientific Name: Kyphosus hawaiiensis
Hawaiian Name: Nenue |
Detailed Description: The Hawaiian Chub is bluish gray, with a darker posterior and light anterior part of its body. Separating these two contrasting colors is a central light stripe.These fish are also black with light colored speckles. It is an oval shaped fish that is about 14-20 inches long. Habitat: This fish lives in small schools of fish, on top of reefs and drop-offs. Hawaiian Chubs are territorial and particular so they are often times found in the same areas over time. These fish prefer to live among coral and reefs, rather than the open ocean. They are found along the main Hawaiian and Line Island groups. There is not too much detailed information about the Hawaiian chubs’ diet because it is a new species. However, its family, Kyphosidae, lives off algae, detritus and small invertebrates. |
Zoology Features: The Hawaiian Chub has pelvic fins that reach its anus. It also has 18 pectoral rays and 12 dorsal rays. The Kyphonsus genus also all have a small terminal head with small teeth to help digest food. Hawaiian Chubs have a bilateral body symmetry, with a skeletal system spilt up, with an Axial skeleton and Appendicular Skeleton and Fins. It is a triploblastic organization and a deuterostome. Basic Growth and Developmental Cycles: Hawaiian Chubs spawn releasing thousands of eggs. These eggs are then covered by sand or gravel. In 2-3 months they hatch as an Alevin. An Alevin is a a baby fish that has the yolk of the egg to feed it for 2 months. After 2 months the Alevin grows into Fry, then to Smolt, which can be compared to a young adult in human growth. After rapid growth, the Hawaiian Chub reaches adulthood.
