Stingray vs Skate

Stingrays and skates are both flat, winged fish related to sharks, and both lie on sandy bottoms with eyes and nostrils on top and the mouth underneath. At a glance, they look nearly the same. The tail is the quickest place to look. Their body plan is nearly identical, so look beyond the outline.

The differences are real but come with exceptions. The roughtail stingray carries thorns, for example. The most reliable difference is reproduction, since skates lay leathery egg cases known as mermaid's purses while stingrays bear live young. Defense, teeth, and size also differ. When in doubt, treat any ray as capable of stinging.

When you are looking at which

Stingray

• The tail is long and whip-like, and a barb sits near its base.
• You are wading in warm shallow water, and the ray buried itself in sand.
• It is part of a ray species known to give birth to live pups.
• The animal is a wide cownose-style ray about 3 feet across.

Skate

• The tail is short and stout, with small thorns along the back.
• A black leathery rectangle washed up on the beach nearby.
• It is a small flat fish, 16 to 20 inches long, in cool northern water.
• It has small pointed teeth rather than crushing plates, if you see the mouth.

How this works

The quiz adds up cues for a stingray versus a skate. Tail shape and an egg case are the clearest, while size, water temperature, and range overlap between species. Answer only what you saw, and use I can't tell for the rest, since a skipped cue is better than a guess.

It compares stingrays and skates in general using species such as the round stingray, cownose ray, and little skate. Guitarfish, electric rays, and manta rays are different groups and are not scored. A tie means your answers were split, so check the tail and stay clear of any ray you cannot confirm.
