Migratory
Spawning
Conger eels have seasonal migrations, moving between their feeding and spawning grounds.
During the mating season, Conger eels migrate to spawning grounds, where they engage in courtship rituals and mate.
Non-migratory
Egg-laying
Pair bonding, both parents care for eggs and fry
Cookiecutter Sharks have been observed to undertake vertical migrations, moving from deeper waters during the day to shallower depths at night. This pattern is believed to be related to their feeding behavior.
During mating, male Cookiecutter Sharks use their specialized teeth to bite the females and hold onto them. This behavior is called 'sucked-in mating'.
Male guards the eggs until they hatch
