Tropical ocean invertebrates such as sea jellies, comb jellies and others...

Class Scyphozoa: 'True Sea-jellies'

Order Semaeostomeae

These jellyfish usually have four arms, but are most recogniseable by the long long wispy tentacles trailing from the bell. The edges of the domed bell are scalloped.

Family Ulmaridae

(Kakaban, Indonesia)

Aurelia aurita, 'Moon Jellyfish'.

Order Rhizostomae

These sea-Jellies have eight 'fluffy' divided arms hanging from the bell, rather than the thin wispy tentacles seen on other jelly fish.

Family Mastigiidae

(Kakaban, Indonesia)

Mastigias papua, 'Spotted Jellyfish'.

(Kakaban, Indonesia)

Cassiopeia ornata, 'Upside-down Jellyfish'.

My first trip after the virus is as Expedition leader in Tasmania with Coral Expeditions (March), followed by my role as biologist guest lecturer on the Great Barrier Reef (April) and Expedition Leader in the Kimberley (May-September). If you can't go travelling until everything settles down, then until then, here I am doing online guided walks for Noble Caledonia and online lectures for Silversea.
