Macro Photography and Video

From Boxer-Crab to Honeycomb butterfly sea slug

You don't always see big fish when diving. It's always worth taking a look at the many little creatures crawling around.

Many are only a few millimeters in size.

The video was filmed in the vicinity of Gangga Island.

Some excerpts from the video

Identifying the species of the animals isn't easy for me, as I'm not an expert. Dive guides are a great help here. Internet help is also available, but it's often difficult to find the right species.

If you find any discrepancies, please let me know. The best way is via E-Mail.

**Nudibranch** probably a Dermatobranchus

**Sapsucking Slug** Ercolania endophytophaga
A tiny, sucking sea slug (Sacoglossa), known for its unique way of feeding: It eats the inside of large bladder algae such as Struvea plumosa, by breaking into the algal cells without destroying them, earning it the name “algal cell eater”.
