pelican eel lifecycle.

Question

how does a pelican eel change in life??!!

Answer 1

their olfactory organs grow, and their jaw and teeth degenerate, and their stomach cavity shrink due to the development of their testes.

Answer 2

The lifecycle of the pelican eel (Eurypharynx pelecanoides) involves a distinct reproductive strategy and post-mating death. Similar to other eels, they begin as transparent, thin larvae (leptocephalus) before transitioning to a juvenile stage. Males undergo significant changes during maturity, including enlarged olfactory organs for mate finding and degeneration of teeth and jaws. Females remain relatively unchanged. It's believed that the eels die soon after mating, possibly as a strategy to maximize the likelihood of offspring survival. 

Elaboration:

• Larval Stage: Pelican eels, like other eels, start as transparent, thin larvae called leptocephalus. 
• Juvenile Stage: They transition into a juvenile stage before reaching maturity. 
• Male Maturation: Sexually mature males undergo notable transformations, including:
  • Enlargement of olfactory organs (responsible for smell) to help locate mates. 
  • Degeneration of teeth and jaws. 
  • Development of defined reproductive organs. 
• Female Maturation: Females do not undergo significant changes as they mature. 
• Post-Mating Death: It's widely believed that pelican eels die shortly after reproduction. This may be a strategy to ensure their resources are focused on producing viable offspring rather than prolonged survival. 
• Reproduction: The eggs are believed to be planktonic, meaning they float in the water.
