Dykning med Haveslangeål

Der er 35 arter af Haveslangeål i familien Heterocongrinae, hvoraf de fleste findes i det indiske Stillehavsområde, og to af dem kan man finde, mens man dykker på Koh Lanta.

De har lange, slanke kroppe, hvor både bryst- og halefinnen er reduceret eller fraværende. Disse ål har ingen skæl.

Haveslangeål forekommer i kolonier i sand, hvor de lever individuelt i huler, hvorfra de stikker op for at spise plankton. Når de rejser sig op for at spise, ligner de en blidt bølgende have af planter.

Mange arter af haveål er farvestrålende mønstrede, og de fleste bliver ikke mere end 60 cm lange.

Parring og gydning foregår uden langvarige vandringer.

Spotted Garden Eel

(Heteroconger hassi)

The spotted garden eel is a small fish that can reach a maximum length of around 40 cm. It has a long, thin body, and the head is the same diameter as the body. The head appears shortened because the large mouth is close to the also large eyes. Adults are around 14mm in diameter.

The body is white and covered with many small black spots. The spotted garden eel has three larger distinctive black spots; the first identifies the gills opening and the position of the tiny pectoral fins, the second is located in the central part of the body and the third one surrounds the anus. Juveniles have a very thin black body.

The spotted garden eel lives in colonies on sandy bottoms that are exposed to currents, ranging from 8 to 45 meters.

As in other garden eel species, individuals rarely leave their burrow once it is finished, but will move burrows closer together during breeding season until contact between partners is possible.

Once the eggs are fertilised, they will grow into juvenile eels within the plancton, before becoming large enough to start living on the sandy bottom of the seabed.
