Pleurosicya micheli

The physical appearance of a ghost goby is that of a tiny fish with a max length of 2.5 cm.^[2] The body of this species is translucent with a reddish-brown mid lateral internally; and also has white stripe markings above the vertebral area with red/blue fluorescent eyes.^[4] The outer layer of this fish also has a reddish-brown hue along the sides of the fish and the face.^[4] The body depth at the anus measures between 5 and 7.1 times in standard length.^[2] The total dorsal fin is 6–7 spines and 7–8 soft rays, while anal fin has 1 spine and 7–9 soft rays.^[2] Furthermore, the sides of the nape have 8–12 scale rows, and there are 22–28 scales in the longitudinal series.^[2] The species also lacks predorsal scales but has scales extending on the sides of the nape.^[2] Pleurosicya micheli also lay their eggs inside ascidians, which are also commonly called sea squirts.^[3]

Pleurosicya micheli can be found in a tropical marine environment in Indo-west Pacific: from the Seychelles to Fiji and the Hawaiian Islands.^[2] This species typically inhabits coral reef slopes at depths of 10 to 50 meters,^[3] residing in hard coral reefs that provide a place for them to live as well as a protection from potential threats.^[3] They usually live in an environment that has temperatures of 24.8 degrees Celsius to 29.3 degrees Celsius.^[3] Hard coral reefs can be used as a protection for them because they are tiny species that can hide inside the crevices of a hard coral reef if there is a predator that is trying to harm them.^[3] They can occasionally also be found inside a clam's mantle.^[3]
