Praise be to Allaah.
Among the blessings that Allaah has bestowed upon us is the fact that
He has made our religion easy for us, and has not made it too difficult or unbearable. He
has allowed us many things that were forbidden according to previously-revealed laws.
Allaah says (interpretation of the meaning): “… Allaah intends for you ease,
and He does not want to make things difficult for you…” [al-Baqarah 2:185].
Hence all kinds of food from the sea are permissible, whether they are
plants or animals, alive or dead. Allaah says (interpretation of the meaning): “Lawful
to you is (the pursuit of) water-game and its use for food – for the benefit of
yourselves and those who travel…” [al-Maa’idah 5:96]. Ibn ‘Abbaas
said: “ Sayduhu (lit. hunting, pursuit) refers to whatever is taken from it
alive, and ta’aamuhu (lit. its food) means whatever is taken dead.”
There are a few things – certain types of water animals –
which some scholars exclude from the permission outlined above. These are:
Crocodiles. The correct view is that eating these is not allowed,
because they have fangs and live on land – even though they may spend a lot of time
in the water – so precedence should be given to the reason for forbidding it (it is a
land animal that has fangs).
Frogs. It is not permitted to eat them because the Prophet
(peace
and blessings of Allaah be upon him) forbade killing them, as is reported in the hadeeth
of ‘Abd al-Rahmaan ibn ‘Uthmaan, who said that the Messenger of Allaah
(peace and blessings of Allaah be upon him) forbade the killing of frogs. (Narrated
by Imaam Ahmad and Ibn Maajah; see also Saheeh al-Jaami, 6970). The
rule is that everything which we are forbidden to kill, we are not allowed to eat; if we
are allowed to eat it we are allowed to kill it.
Some scholars exclude sea snakes, but the correct view is that as they
live nowhere except in the water, we are permitted to eat them, because of the general
nature of the aayah (interpretation of the meaning): “Lawful to you is (the
pursuit of) water-game and its use for food – for the benefit of yourselves
…” [al-Maa’idah 5:96].
Otters and turtles. The correct view is that to be on the safe side, it
is permissible to eat them after slaughtering them properly, because they live both on
land and in the sea. Here the rule is that in the case of animals that live both on land
and in the sea, the rules concerning land animals should be given precedence, to be on the
safe side, so they must be slaughtered properly, except for crabs which do not need to be
slaughtered, even though they live both on land and in the sea, because they do not have
blood.
Everything that can cause harm is forbidden as food, even if it comes
from the sea, because Allaah says (interpretation of the meaning): “… And do
not kill yourselves (nor kill one another). Surely, Allaah is Most Merciful to you.”
[al-Nisa’ 4:29] and: “… and do not throw yourselves into
destruction…” [al-Baqarah 2:195].

And Allaah knows best.
