Top 5 Micro Marine Animals in Amed

Whether you’re into Macro Photography or just want to take a closer look at the variety of small underwater creatures: this article might help you to find and identify some of the most fascinating little critters Amed area has to offer.

Nr. 1- Nudibranch and other sea slugs

Starting off with one of the most diverse marine animals in matters of shape, size and colour: the Nudibranch. Their scientific name, Nudibranchia, means ‘naked gills’ and describes the feathery gills and horns that most wear on their backs.

With over 3,000 different species, you will not get bored searching for these beautiful little creatures. Their size can range from 0.25 inches (around half a centimeter) to as big as 12 inches (around 30 centimeters), but their bright, colourful appearance usually makes them quite easy to spot. When muck diving the chances are high to find “nudis” (as most Nudibranch connoisseurs refer to them), but they can also be found on a variety of different corals, rocks or sandy slopes. Amed Wall, Ghost Bay or Tulamben Drop Off are generally great choices for a successful Nudi-Hunt.

Nr. 2 – Frogfish

It is quite more difficult to spot this micro marine creature: the frogfish. They have the ability to “mimic” their surroundings in both form and color which makes them masters of camouflage. These grumpy looking anglerfish are usually found camouflaged in sea fans, sponges, rocks or among the sand. Their colours can vary from yellow, pinkish red, white to full-on red. The best dive spots in Amed for finding frogfish are Ghost Bay (especially at night), Jemeluk Bay, Tulamben Wall or Drop-Off.

Nr. 3 – Squid, Octopus, Cuttlefish

Cephalopods are the most intelligent, most mobile and the largest suborder of molluscs. Squids, Octopuses, Cuttlefish and their relatives display remarkable diversity in size and lifestyle with adaptations for predation, locomotion, disguise, and communication. These “brainy” invertebrates have evolved suckered tentacles, camera-like eyes, color-changing skin, and complex learning behavior. A great variety of them can be found along the coasts of Bali and if you look hard enough and explore each and every crevice you’ll be sure to spot some common reef squids, bobtail squids, pygmy and broadclub cuttlefish, coconut and mimic octopuses or even a blue ringed octopus (makes sure to stay away from this one, as they are extremely venomous and one of the most dangerous animals in the ocean). 

Specifically in the Amed area you should check out Jemeluk Bay or Pyramids by night or day to spot these fascinating creatures.

Nr. 4 – Crabs and Shrimps

Continuing the trend of incredible diversity in this list, let’s take a quick look at some of the crustaceans you will be able to find in Bali. 

You can find them in between various corals, underneath rocks or even hitchhiking on a Nudibranch. Most notoriously found are harlequin shrimp, mantis shrimp, colmani shrimp, anemone shrimp and imperial shrimp (just to name a few favourites). 

As far as crabs are concerned they will most likely hide in sandy slopes or underneath a coral/rock-formation. The possibilities seem endless, as you can find almost anything from orang-utan crabs, reef crabs, porcelain crabs to hermit crabs and many more.

Be sure to visit Jemeluk Bay and Wall, Pyramids or Ghost Bay. A nightdive would be ideal, as crustaceans usually come out of hiding when it’s nice and dark and you’ll have an easier time spotting them.

Anemone Crab can be found on almost all sites

Nr. 5 – Ghost Pipefish and Seahorses

Closing off with probably the hardest to spot category: Seahorses and Pipefish.

They are not only rare but also quite difficult to spot. Seahorses in Amed are mostly very small and well camouflaged. Especially seahorses like the yellow (thorny) seahorse or pygmy seahorse won’t be easy to find, but who doesn’t like a challenge? While seahorses prefer shallow waters and to hide in between algae or different species of gorgonian coral (soft coral), pipefish on the other hand are usually found hanging out inside wrecks or close to mooring buoys. 

Try your luck at one of the world’s most famous shipwrecks, the USAT Liberty Shipwreck in Tulamben or the Japanese Shipwreck in Bunutan (Amed area).

Nudibranch Anatomy

Every diver loves nudibranchs. But do you know your nudibranch?

Kingdom: Animal, Phylum: Mollusca, Class: Gastropoda. Subclass: Heterobranchia,
Clade: Nudipleura.

Nudibranchs meaning “naked gills” are invertebrates. These mostly shell-less mollusks appear in dozens of different shapes, sizes and colours. Up to this day there have been at least 2.000 species of nudibranchs (short: nudis) discovered.

Nudis are amongst macro photographers’ most favourite subjects because of their extraordinary appearance. Generally, nudis can be divided into two classes: AEOLID & DORID NUDIBRANCH

AEOLID NUDIBRANCHIA

Aeolid nudibranchs are characterised by having long, narrow bodies with numerous finger-like projections, called cerata.  They have a pair of oral tentacles, parapodial tentacles, and rhinophores on their head (McDonald 1999).

A) Oral Tentacles are sensory feelers used to help the slug feel its way over the terrain

B) Rhinophores are chemical sensors on the head that are used to detect chemicals in the water (Ellis 2001)

C,D) Cerata are thin, finger-like projections of the digestive gland of the slug. Some nudibranchs have photosynthetic zooxanthellae from the coral in its cerata (Tackett and Tackett 2003).  The Cerata are also used in defense.  The tips of some cerata can contain poisonous substances (D) (Picton and Morrow 1994).  Cerata can also be cast off when the nudibranch is alarmed. 

E) Acid Glands produce defensive acid secretions against predators. 


DORID NUDIBRANCHIA

A) The Branchial Plume allows Dorid Nudis to filter oxygen from the water and breathe

B) Rhinophores are chemical sensors on the head that are used to detect chemicals in the water (Ellis 2001)

C) Oral Tentacles are sensory feelers used to help the slug feel its way over the terrain

D) Nudibranchs are hermaphroditic, meaning they are both male and female at the same time, but they cannot fertilize themselves. For reproduction, nudibranchs stick together in a dance-like act. Eggs are being deposited in each individual. Some nudibranchs have their anus on the same area as where the reproductive opening is located, others have their anus located in between the branchial plume.

E) Acid Glands produce defensive acid secretions against predators.
