"Umbrella Crab" (Cryptolithodes sitchensis)

Also known as the Sitka crab or the Turtle Crab, the umbrella crab is a species of lithodid crab that is native to coastal regions of the northeastern Pacific, ranging from Sitka, Alaska to Point Loma, California. C. sitchensis is noted for having a unusual half-moon shaped carapace that extends over its walking legs and chelipeds, this serves as a form of camouflage allowing C. sitchensis to blend in with the rocks around it.  The color of C. sitchensis’s carapace is highly variable and often matches the color of the coralline algae with C. sitchensis feeds on.

An absolutely gorgeous tropical earwig, couldn’t find a species name anywhere. Earwigs have always been some of my favorite insects, it’s really unfair how much people loathe them when they really can’t harm people at all, nor are they significant household or garden pests.

I think it might be Allodahlia scabriuscula?
(Also important PSA about earwigs :D)

"Giant Sea Spider" (Colossendeis colossea)

…a large species of sea spider (not a true spider but distantly related) that has been observed in deep waters worldwide. True to its name C. colossea is the largest species of pycnogonid known to science, with individuals reaching leg spans of around 2 ft! Like other sea spiders this species is a carnivore/scavenger and likely feeds on sessile invertebrates by inserting its proboscis into them and sucking out their insides.

Pachyloidellus goliath

…a species of tropical harvestman that is native to Argentina in South America.  P.goliath is mainly active at night and is a generalist predator and has been observed feeding mostly on earthworms and a variety small insects. Like other harvestmen species when threatened P.goliath can secrete a defensive secretion which produces a strong odor in attempt to deter potential predators.

Tasmanian Live-bearing Seastar (Parvulastra vivipara) - Requested by Anonymous

The Tasmanian Live-bearing Seastar is a tiny, uniformly orange-yellow seastar, up to 15 mm across. It is endemic to south-east Tasmania. Parvulastra broods juvenile starfish in a brood chamber (aka “live birth” aka viviparity). That, is the adult “carries” either internally or externally several tiny juvenile starfish with it until they are ready to move off on their own as full adults.

But what motivates the exit? Those juvenile starfish are cannibals! So, as soon as the brooded juveniles develop a mouth they begin feeding on their siblings in the body cavity! Byrne speculated on one reason that juveniles may vacate in order to avoid being fed upon by their larger siblings. Thanks to the intragonadal cannibalism however, sometimes you get a really big one which continues to grow inside the parent. Ultimately reaching a size at which it cannot physically escape on its own.

Spider-tailed Horned Viper (Pseudocerastes urarachnoides)

In 1968, the Second Street Expedition across Iran collected what appeared to be a Persian Horned Viper with a Wind Scorpion attached to its tail. Examination of the specimen in 1970 revealed the apparent arachnid was actually a growth, but it could not be determined if it was some sort of reaction to a parasite, a tumor, or caused by genetics. A second specimen bearing a pseudo-arachnid was captured in 2001, and it became apparent that an entire species possessed this trait — Pseudocerastes urarachnoides (Bostanchi et al. 2006). Two live specimens were collected in 2008 and the tails were filmed in action.

An unnervingly convincing Wind Scorpion probably doesn’t seem very appealing to most humans but Bostanchi et al. (2006) hypothesized the heavily modified tails are used as lures.

Oarfish (Regalecus glesne) - Requested by Anonymous

The strange-looking oarfish is the longest bony fish in the sea. The origin of the oarfish name is unknown, but may refer to the oar-shaped body or the long, oar-like pelvic fins. Because of its long, thin shape, the oarfish fish is sometimes known as the ribbonfish. It is also commonly referred to as the king of herrings.

Even though it is a deep water species, it is not too uncommon to see an oarfish. These unusual creatures have been known to wash ashore on beaches after storms, providing endless hours of fascination for curious onlookers. They also have a habit of floating near the surface of the water when they are sick or dying. Because of this, it is believed that the oarfish may be responsible for many of the legendary sightings of sea monsters and sea serpents by ancient mariners and beach goers.

Although it is fished for sport as a game fish, the oarfish is not usually fished commercially because its gelatinous flesh is not considered edible.
