The piece colors don't look very aquatic to me; polution of the oceans isn't that bad yet... I would more expect something like #C0E0FF and #40D09C.

With pieces that capture as locusts it will be very difficult to checkmate a bare King, and consequently, the game will be very drawish. If my King can reach a corner (and I don't see how you could prevent me from doing that already in the opening) it has become impossible for you to win. None of the pieces can attack the corner, so my King is absolutely safe there. I can abandon all my other pieces, and it would still be draw. You can attack all squares around it, but that would stalemate me if I am in the corner, and just make me step back into the corner otherwise. (Compare the KBPK end-game with Rook Pawn and wrong Bishop.)

Variants with pieces that capture like this usually have an extra rim around the board where you are able to land after such a capture, but cannot otherwise move to (e.g. Roccoco). Of course you could declare stalemate a win. That would solve the safe-corner problem, so that you might be able to force stalemate with two Tritons. Note that Prawns, Seahorses and Nereids can never attack any edge square.

You could also make pieces check the same way as they move without capture, rather than as they capture. But that would make all checkmating of a bare King just normal Chess, which probably is less fun.

To thor: [cQ-mQ] is Lion-Locust, Locust is [cQ-mK]. In Marine Chess, Pawns and Kings are normal, variant where Pawns and Kings are also marine is called Ultramarine Chess (so this variant is actually already exist since around Mark A. Ridley's 40th birthday). If you want to mention the inventor of Marine pieces, it's Giuseppe Brogi. If you want to mention other marine piece then you might want to include Marine Moo which is called Hippocampus {mcafsmK}. Other variant used in chess problem that you might want to include here is Chimaera Chess which is Ultramarine+Chinoise.

To nelk114: Prawn is mentioned in Julia's Fairy Classification – TABULAR

The British Chess Problem Society's Fairy Glossary does list the lot; there the Marine Pawn is just Marine Pawn. Personally, I like your use of Prawn, for both the imagery and the wordplay.

‘Marine’ here is a problemist usage; most of these names do seem to be standard for these pieces in the Problem world (though my go‐to source is in German so there may be differences). ‘Prawn’ for Marine Pawn differs from German usage of ‘Matelot’, or Sailor, but since I don't immediately find any English‐language references to Marine pieces that name the Pawn analogue I'm willing to let it stand.

I'll do a more thorough check later but I don't expect it'll get in the way of publishing this

A great marine style chess variant is called Aquachess. I am using a similar approach in Titanic Chess. And I am using Nereids in my game for a completely different purpose. Maybe your game needed a different name. Let's see what the editors have to say about it.
