  • It is recognizable from its large head with rubbery lips.
  • A relatively poor swimmer, the megamouth has a soft, flabby body and lacks caudal keels.
  • Reproduction is ovoviviparous, meaning that the young sharks develop in eggs that remain within the mother's body until they hatch.
  • Megamouth sharks are considered to be a species of "Least Concern" on the IUCN Red List.
