Neomyxine biplinicata is an eel-like hagfish. When they sense a threat, they excrete a substance from their pores that turns into a jelly-like fluid when mixed with water. This jelly-like fluid can either trap predators or clog their gills.

Question

Which two systems alert the hagfish to danger and help produce the slime that it uses as a defense?
Integumentary and nervous systems
Nervous and digestive systems
Excretory and reproductive systems
Immune and respiratory systems

Answer 1

The correct answer is Integumentary and nervous systems.

The integumentary system is involved in the production and secretion of the defensive slime, while the nervous system helps detect threats and trigger the release of the slime.
