Invertober days 17-21: European glowworm (well, a dragon based on it), Anna’s magnificent sea slug, yellow tube sponge, three-banded lady beetle, and strawberry squid!

[Image description: Five digital drawings.

Image 1: A wingless dragon based on the European glowworm. Most of its body is a pale peachy colour, except for the blunt-tipped horns, claws, and armour scales going down its back which are all dark brown. Its eyes are a bright yellow-green, as are the four-pointed stars on the tip of its thick tail and horns. Text below: Arthropoda • Insecta • Coleoptera • Lampyridae • Lampyris noctiluca

Image 2: An Anna’s magnificent sea slug, a sea slug with a blue and black body surrounded by a yellow and white “fringe”. Its antennae and cerata are orange. Text below: Mollusca • Gastropoda • Nudibranchia • Chromodorididae • Chromodoris annae

Image 3: A yellow tube sponge. It looks exactly as its name would suggest. Text below: Porifera • Demospongiae • Verongiida • Aplysinidae • Aplysina fistularis

Image 4: A three-banded lady beetle, a ladybug with five rectangular bands instead of spots, one going across the middle and two pairs at the sides. Text below: Arthropoda • Insecta • Coleoptera • Coccinellidae • Coccinella trifasciata

Image 5: A strawberry squid. It is red with bright green eyes of different sizes, the left being significantly larger than the right. Text below: Mollusca • Cephalopoda • Oegopsida • Histioteuthidae • Histioteuthis heteropsis

Goniobranchus reticulatus is a species of colorful sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae. There is considerable disagreement amongst experts over the identity of Goniobranchus reticulatus. It has been widely reported from the Indo-West Pacific Ocean, but many of these records are now believed to be of distinct species.

Nudibranch Size comparison 

We’re used to seeing nudies in close-up shots, which can make it difficult to tell their size. Here is a pic of a nudie (likely from the family Chromodorididae) with a thumb for scale. 

NOTE: While this guy is tiny, nudibranchs range in size from 6 mm - 30 cm.

This is the flamant Sechuran Desert Nudibranch (Felimare sechurana), a recent described new species of seaslug from the Sechuran desert coastline of North Perú.

Previously mistaken with the California blue dorid (Felimare californiensis), a genetic and morfometric study found out it was a complete new species. The genetic difference between these two sea slug, could be the result of dispersal of members of an ancestral population across the tropical eastern Pacific during the repeated periods of glaciation during the Pleistocene (approximately 1 - 2 million years ago), followed by isolation.

Nudibranchs, often casually called sea slugs, are marine gastropod molluscs which shed their shells after their larval stage. Are found worldwide, and play a fundamental role as biological controllers of corals, anemones, hydrozoans and marine sponges.
