[Coral-List] seahorse males develop placentas for young

[Douglas Fenner]

Most seahorses live in seagrass beds, but at least one or more tiny species
live on sea fans on which they are super camouflaged and which surely are
on coral reefs.
     If I remember, much of the reproductive biology is shared with
pipefish, which show a series from eggs external and glued on to small
pouch walls to both sides of the eggs, to complete pouch walls that
surround them.
      I remind that some sharks have placentas as well.

Male seahorses grow placentas to incubate their young.

Slashing emissions by 2050 isn't enough.  We can bring down temperature now.
