Kogiidae
Sign in to saveKogiidae is a family comprising at least two extant species of Cetacea, the pygmy (Kogia breviceps) and dwarf (K. sima) sperm whales. As their common names suggest, they somewhat resemble sperm whales, with squared heads and small lower jaws, but are much smaller, with much shorter skulls and more notable dorsal fins than sperm whales. Kogiids are also characterized by a "false gill slit" behind their eyes.

Dwergpotvissen (Kogiidae) zijn een familie van walvissen. Naast het levende geslacht van de echte dwergpotvissen (Kogia) omvat het de fossiele geslachten Kogiopsis, Miokogia, Praekogia en Scaphokogia. Ze zijn nauw verwant aan de potvissen (Physeteridae) en worden vaak tot dezelfde familie gerekend. Er zijn maar twee levende soorten: Dwergpotvis (Kogia breviceps) Kleinste potvis (Kogia sima) De dwergpotvis en de kleinste potvis zijn heel moeilijk te onderscheiden: de kleinste dwergpotvis is een beetje kleiner en blauwer van kleur. De vorm van de kop en lichaam zijn nagenoeg hetzelfde.
