Introduction


 Currently (November 2017) 43 seahorse species are recognised.

Characterised by long tubular snout and long bony shell.

Exceptional brood care:

The male has a brood pouch in which up to 150 eggs are laid by the female,

which are then fertilised and incubated for three weeks.

The smallest species Hippocampus denise is only 13.5 mm in size,

the largest species Hippocampus abdominalis

and Hippocampus bleekeri grow to 35 cm.


Hippocampus bargibanti

Bargibant's seahorse or Pygmy seahorse

 Maximum length: 1 - 2 cm

Depth: 25 - 50 m

This species lives on various soft corals, which are also its food.

It seems as if the corals live symbiotically in the skin

and produce short stings and wart-like bumps on their bodies.

This gives them perfect camouflage, they are very difficult to see,

magnifying glasses are helpful.

Hippocampus kuda

Common seahorse, Estuary seahorse, Yellow seahorse

or Spotted seahorse

 Maximum length: 20 cm

Depth: 0 - 70 m

Thanks to Muelly from Meereslexikon for the identification,

as the kudas are not recognised as such,

as identification is difficult for the layman.

The animals usually have small threads of skin on their snout.

Pontoh's pygmy seahorse or Weedy pygmy seahorse

Maximum length: 1 cm

They live in close association with invertebrates

They can be distinguished from previously identified seahorses

by their body proportions, the different body appendages and their colour.

They have only one gill opening on each side.
