Realistic sea humanoids

+0
−0

bucking the trend of mermaids I've decided to take a different approach with my mermaids. A long time ago a group of Australopithecus diverged from us taking to the sea. some characteristics of these pseudo-mermaids" are:

  • are 149.3cm (4.9ft) tall
  • are a grayish color
  • have a thick layer of blubber
  • have human level intelligence
  • have webbed hands and feet
  • have some type of echolocation but can communicate like humans (optional)
  • are omnivorous (but lean more to the carnivorous side)
  • have slit like noses (lacking a sense of smell)
  • thighs have started to become fused
  • can hold their breath for up to 15 minutes (but still need to resurface for air)

Given these characteristics could such a hominid realistically exist?

NOTE: magic does not exist in my story
