Notacanthidae
Template:Short description Template:Automatic taxobox
Notacanthidae, the deep-sea spiny eels, are a family of fishes found worldwide below Template:Convert, and as deep as Template:Convert.
Their bodies are greatly elongated, though more tapered than in true eels. The caudal fin is small or nonexistent, while the anal fin is lengthy, as long as half of the total body length. They feed on animals attached to or living on the sea floor, such as sea anemones, echinoderms, molluscs, and worms.[1]
Although not true eels, these fish do have a similar leptocephalus larval form. However, while the larvae of true eels are about 5–10% of the length of the adult, those of deep-sea spiny eels can grow considerably larger than the adult, and shrink when they develop into their final form. Thus, while adults range from Template:Convert to Template:Convert in length, larvae of up to Template:Convert have been recorded.[1]
