Striped Pyjama Squid

(Sepioloidea lineolata)

also known as the Striped Dumpling Squid, Despite it’s name it is actually a cuttlefish of the order (Sepiida). They are native to the Southern Indo-Pacific centered around Southern Australia. while it may look cute it is actually fairly poisonous, it is pretty small and grows up to 2 in in length. they tend to bury themselves in the sand where their heads are only visible probably for protection/hunting.

Reticulated Hillstream Loach (Sewellia lineolata)

Also known as the Tiger Hillstream Loach, the reticulated hillstream loach is a species of river loach that is native to Vietnam.  Like other hillstream loaches S.lineolata is a rheophile, an animal that inhabits rapids, and is often seen clinging to rocks with its modified ventral fins. Reticulated hillstream loaches are active during the day and will feed mostly on algae but are known to eat small benthic invertebrates as well.

I follow you because you like pokemon too, reblog quality content, write real well, and seem like a pretty kickass person. As an added bonus, following you also gives Duran aneurysms for having irl and internet friends in the same place at the same time.

I keep trying to tell myself that making my good friends uncomfortable is supposed to be a bad reason to do something

But this is one of those cases where I just have to smile and high five you.

Kick ass! Adamant is a great nature for a metang too!

Tbh I don’t know much about Natures, but I know Adament is one of the “good” ones so I might keep him and use him on my Black2 team????

Philinopsis lineolata

…is a species of headshield slug that is distributed throughout the Tropical Indo-West Pacific. Like other members of Aglajidae this species is a carnivore and will usually feed on other molluscs and marine worms. Its ‘headshield’ holds a muscular buccual bulb which it uses to catch prey.

Striped Pyjama Squid, Sepioloidea lineolata.

Let’s talk about how Pyjama squids are being misrepresented as cuttlefish. They aren’t - they’re actually sepiolids! Members of the sepiolid family are commonly known as squids (Pyjama Squid, Bobtail Squid, etc.) but they are closer to cuttlefish. However, they lack a cuttlebone and so are not true cuttlefish. They may also be known as stubby squid or dumpling squids.

Part 19 of my documentary, “Mucky Secrets”, about the fascinating marine creatures of the Lembeh Strait in Indonesia.

In this video we study how sea slugs (including nudibranchs) feed and mate.

All known nudibranchs are carnivores. The biggest family of nudibranchs, the chromodoridids, feed exclusively on sponges.

Most sea slugs have a ribbon-like tongue covered in microscopic teeth called a radula to help them consume their prey. The form of the radula varies greatly and is important as a basis for taxonomic classification.

We see a pleurobranch, Pleurobranchus forskalii, a different type of sea slug, feeding on an ascidian, or “sea squirt”, a type of tunicate.

Nembrotha nudibranchs also feed on ascidians. We see a Nembrotha lineolata feeding on a blue club tunicate. The ascidian feeds by filtering plankton from the water with its delicate, blue, sieve-like interior enclosed in a clear outer sac, its tunic. The sea slug everts its proboscis, its oral tube, out of its mouth and, with ruthless efficiency, sucks this fleshy interior right through the tunic. The radula teeth enable the slug to deal with the tougher parts of the sea squirt’s intestines.

Most sea slugs are quite specific in their choice of food, and so they are often drawn towards the same place. This increases the chances of encountering others of the same species and finding a mate. As they have no vision, nudibranchs locate each other initially through smell then touch.

During copulation, they line up their genitals which are on the right side of their body. All sea slugs are hermaphrodites and contain both male and female reproductive systems. During mating, each nudibranch receives sperm from the other.

We see a pair of Nembrotha purpureolineata nudibranchs mating. The penis, which is off to the side, is covered in tiny, sharp barbs which lock it into the vagina, which is at the centre of the stalk. The male organs often mature before the female ones. Small nudibranchs with an immature female reproductive system can store the sperm they receive until they start producing fertile eggs.

We also encounter a mating pair of Hypselodoris bullocki nudibranchs. Their genitals are also covered in tiny spines that anchor them together during copulation.

After fertilisation, a mucus-bound ribbon of eggs is laid in a spiral, often on or near the species’ food source. Most egg masses are toxic to predators and are abandoned by the parent.

Hypselodorid nudibranchs often follow each other around, top to tail. The reason for this ‘trailing’, or “tailgating” behaviour is a mystery. It’s thought to be a prelude to mating, but in some cases the trailing slug might simply be getting an easy ride in the search for food.
