Learning about eels

Don showing us the size of an eel he caught


Last week on the 22nd of March Don an eel scientist came to talk to the Batten team.
We learnt that there were three different types of eel in New Zealand.
There is the Longfin eel the Shortfin eel and the Australian Longfin.
Most of the stuff he told us we already knew but he was just confirming
# the facts that we had learned.

Eels don't need to eat everyday because they eat (inhale) large chunks of food.
Sometimes young ducks only have one leg because eels have arrow sharp teeth
facing backwards.
Not only do they not need to eat but nor do they have to move to
get water through their gills unlike
other fish.

Australian Long Fins are only found in the North Island.
Eels go to Tonga to breed. The female eels lay their eggs
and the males fertilise the eggs.
They can between lay 7 - 50 million
eggs.
The biggest eels can grow to two metres LONG, and can live to 112 years old.

The way you can age them (after they have died) is by cutting the head in half
take out the ear bone and count the rings.
